Night Flight Calls

The most recently received Mail is at the top.

Well, I'm glad people still consider "Out of the blue" a useful  
publication, but it was never meant as a comprehensive guide. In fact  
it was a 25th anniversary present to Dutch Birding subscribers. It  
only covers some families and lacks, for example, hirundines,  
accentors, finches and most non-passerines. It was also very much  
orientated towards diurnal migration, although it should be useful  
for nocturnal migration too. Unfortunately supplies of "Out of the  
blue" are running low, and I think it is only available to new  
subscribers of DB. We've been collecting recordings for a more  
thorough replacement for some time but at least two other projects  
need to be completed first.

There is also a much older cassette/CD publication by Claude Chappuis  
called Migrateurs et hivernants, which contains many interesting  
recordings of migrants. It is pretty accurate with a handful  
exceptions. Chappuis has also published a north African sound guide,  
which is highly accurate, covers most of Europe as well, and is  
useful for learning migration sounds too.

all the best,

Magnus

Hello, Everybody.
 
The basic reference for Europe, as far as I am aware, is the 2-CD set,
"Out of the Blue: Flight Calls of Migrants and Vagrants." It's by Arnoud
van den Berg, Mark Constantine, Magnus Robb, and The Sound Approach
(2003).
 
Magnus, you out there? Do you want to say anything specific about this?
All I can say, from my rather distant perspective, is that I've greatly
enjoyed listening to the recordings on "Out of the Blue." Next time I
hear a Lesser Short-toed Lark on nocturnal migration over central
Colorado, I'll be prepared...

Hello all, 

Plainly out of curiosity, I'm wondering what types of resources are
available 
to those who are interested in learning more about NFCs of European
migratory 
passerines.  Are there any recording sets that would be recommendable,
or 
literature (with spectrograms?) as well?  

Thank you and happy spring migration,

Snow Geese were the most audible migrants locally 3/15-17. Each March, about 
10% of the ~one million Greater Snow Geese stage in about 5 counties in se 
PA. There was a mass exodus since the end of the monster storm Monday, 3/15. 
For example, the estimated number at Middle Creek WMA in Lancaster Co. was 
120,000 3/16; today the number was <10,000. Many people in these counties 
reported hearing Snow Geese the last few nights; don't know if they showed 
up on radar or anyone's recording equipment. They are heading ne toward 
Quebec.

Hi Andrew,

Great discussion. As a person recording NFCs from a "hobbyist" 
perspective, I really appreciate the knowledge you and others bring to 
the list.

Question about Brown Creeper NFCs. The Evans/O'Brien Flight Call CD 
mentions that Brown Creepers are "not known to call at night." Can I 
assume this knowledge has changed since the CD was published?

Hi all,
Just a few comments to catch up on all of these threads.  And a big
welcome back to all of those checking this list regularly!

Broadly, no, I don't think so - this week should see some nice
movements given the return flow that's been building since the
nastiness of last weekend moved past.  However, if you're hoping for a
flight with the magnitude and diversity of some spectacular fall
movements, probably not.  Such large calling events appear to be
generally rarer in spring than in fall; they can occur, especially in
places like coastal Florida and Texas certainly in May; and it's quite
possible that larger calling events occur with some greater regularity
even this early in the season - honestly, not enough data to say,
because most nocturnal acoustic monitoring programs start after the
first Song Sparrows and American Tree Sparrows and such (and
waterfowl) begin moving north!

To follow up on these questions and on what David and Brian were
discussing and additionally to frame in terms of vocal behavior. . .
I agree, winds are of great interest (and annoyance sometimes)! In the
modeling for BIRDCAST about 10 years ago (and in Sid Gauthreaux's and
Ken Able's modeling 30 years prior to that), we found that wind speed,
direction, its decomposition into vectors at the surface were useful,
without question, in predicting radar reflectivity in simple (!)
regression models for the mid-Atlantic and Northeastern US.  Not
surprisingly, the position of pressure centers, presence and
distribution of rain, temperature and relative humidity measurements
(all surface level) were correlated in various ways and related to our
success in forecasting migration on WSR-88D (there are some good
papers by Able, Richardson, Erni et al. and others I can dig up if
people are interested).  We also used wind speeds aloft at 900/925 mb,
which were particularly valuable when thinking about the more regional
extent of favorable conditions for migration - for example,
considering the wind speed, direction, vectors at that level allowed
us to consider how birds might favorably exploit the lowest 500-700 m
above the ground if they were moving on that night and over what
geographic distribution that movement might occur, rather than the
more local forecasting of winds, temperature, humidity, etc.  BUT,
these factors in total were not always important in forecasting a
large calling event - this was decidedly more complex, requiring
consideration of cloud ceiling, cloud cover, and then some factors
that we could not/did not consider like artificial lighting and
ambient noise conditions.  Generally, and the extent of the modeling
of this is still in it infancy in my estimation, increasing cloud
cover and decreasing cloud ceiling were decent predictors of higher
calling events, especially in the presence of seasonally appropriate
winds and proximity to boundaries between air masses, even if you
controlled for varying bird densities as depicted on WSR-88D. However,
we never had quite enough analysis to have much power with these
models - so I still think of these as trends that need more robust
analysis!

I'm blathering on and on here - the point is, there is SO much cool
analysis to be done. . .

Great thread Andrew/Andy/David/Brian.

Best,
Andrew (F)

Hi all,
Good discussion. I'll chime in further later on about the winds and
migration - much to say about that. . .but on a more proximal note, an
interesting assortment of calls from vocal migrants moving tonight in
NYC including Hermit Thrush (4), Brown Creeper (2), Red-breasted
Nuthatch (2), White-throated Sparrow (8), and Song Sparrow (5) among
others.  Not huge numbers (44 calls in the last 1.5 hours), but
decent.

Best,
Andrew

Winds are indeed interesting. Several questions arise:

Do birds use surface winds to "decide" whether to go or not, or do they use
a combination of surface variables such as barometric pressure, rH, etc.,
and/or how much do they "test the atmosphere" (we do know that this occurs,
where birds will take off, and then facing opposing winds soon afterward,
will return to the surface) given a range of surface wind conditions?

I'm including surface winds in this preliminary model (actually, I'm using
wind vectors, to make linear an otherwise circular variable, which takes
into account both wind direction and speed to produce a variable that ranges
from head-wind to tail-wind). The initial model does show this as being
quite important in predicting migration intensity (high tail-wind vectors
appear to be good predictors of high density migration events). I plan to
include wind vectors aloft as well, as a separate variable, and yes, I
suspect they will be important predictors.

Most nocturnal migration occurs within the first few thousand feet, so in
the case of tonight, it looks like birds are moving under SSW winds at the
surface to W winds up to about 3000 feet ASL (according to the Wallops
Island radiosonde). These winds are averaging 10kts, which is a nice tail
wind given a southerly component, and is still quite manageable with a
westerly cross wind. On average, birds moving over the mid-Atlantic in
spring take a SW->NE trajectory, so some west in the wind can still
contribute to a tailwind.  I suspect that had the winds been more northerly
at 900mb (~3000ft) but all else remained constant, you'd still see birds
moving tonight albeit at a lower altitude.

Cheers

David

The question that I like to ask of all this is which level of winds matters the 
most when talking about migration? I am seeing that others are taking into 
account the surface wind direction (NWS observations and forecasts), but what 
about above that? The winds change direction dramatically with height quite 
often, especially in areas where the surface friction is high like large 
cities, so how much are the higher level winds taken into account? If the model 
predictions are right from this morning for tonight, then the winds in both of 
your locations about a kilometer up in the atmosphere should be out of the WNW. 
Shouldn't that hinder the movement of birds tonight?

Andrew- I'm running a multiple regression right now on weather data related
to migration intensity and several of the variables you mentioned are
included. Something I'm meaning to do is to include time-since-last
migration event but have yet to create the variable. I'll let the list know
when I've got something conclusive.

Cheers

David

...I really have to retrain myself to check this list now that migration is
back in action!

Yeah, birds are moving over the mid-Atlantic tonight. There appears to be a
nice flight over the Delmarva Peninsula and into New Jersey, with less
movement over coastal NC and heavy movement out of Raleigh/Durham, NC and
Norfolk, VA. We should see a more widespread push over the weekend and into
next week when southwesterly flow connects the Gulf states with the
mid-Atlantic... this should be part of the winter-cleaning, but will
probably bring more solid numbers of early migrants wintering in the
southern states (Yellow-throated and Pine warblers, as well as LA
Waterthrush, to name a few).

Good Listening!

David

Andrew,

I think certain early migrating species might take advantage of 
tonight's weather conditions. There has not been a night like this 
around my house in many weeks. Although NWS here in Washington DC region 
only has wind out of a southerly component for 3 hrs before switching 
back to north by early morning

I recorded last night from 11:45 PM to 6 AM and had the following:

Song Sparrow 3-4
Savannah Sparrow 2
Ring-billed Gull 1
Canada Goose flock
Tundra Swan (sounded like only a few birds)
Possible Barn Owl

I will be recording tonight. West winds are usually quietest nights 
around my area because it tamps down the auto noise from Interstate 270.

Is this too early for a big NF in the mid-atlantic region?

Are these the main factors?
1) Date during migration season (higher numbers during peak)
2) What has happened during previous nights - i.e. if the wind was
blowing strongly in the wrong direction or
3) Wind speed and direction

It should have been backed up recently with all the rain and northern
winds.  Wind is out of the WSW tonight. But, is it still to early for
a big spring NFC?

Andrew,

I personally like the spring recording better. The subdivision where I 
live is quieter on spring nights and I get better recordings. In the 
fall I have to contend with insects and neighbors A/C units plus there's 
a food warehouse about a mile from my house who's refrigeration 
compressor really thrums loudly on nights with wind out of north direction.

I also feel (but not scientifically proven) that the progression of 
spring migration from an nfc standpoint is more orderly and predictable. 
If winds cooperate, I start recording in late Feb/early Mar. Song 
Sparrows seem to be some of 1st birds I record. Keep hoping I will 
record a definitive Fox Sparrow call but it has not happened yet. Last 
year, I picked up a Song Sparrow flight call on Feb 26. But it was only 
flight call I got that night in almost 8 hrs of recording. I reported to 
nfc-l a few days ago that I had 3 Song Sparrow calls in wee hrs of March 
10. My March recordings since 2006 seem to be mostly made up of calls 
from Song Sparrows, Killdeer, American Robin, Ring-billed Gull, Tundra 
Swan and Canada Goose, an occasional snipe and American Woodcock, and 
towards end of month, American Bittern.

Good question about what happened to sparrows and other birds this 
winter. I really enjoy driving roads a few days after snowstorms to look 
for birds driven to plowed road shoulders. After the big December snow 
here in Wash, DC area, road sides were full of birds. Driving the roads 
in February 4/5 days after back to back 15"+ storms, road sides birds 
were extremely scarce. If the weather had been more cooperative, I 
should have put my recording gear out to see I could get some flight 
calls of birds unexpectedly having to move further south for a second 
time this winter. Hope they are programmed to be flexible enough to do 
that and did not just die. White-throated Sparrows still seem very scare 
around my county.

Next batch of south winds looks like it will be this Saturday. Keeping 
my fingers crossed that they will be light and it will be a dry night.

Good recording,

Andy Martin
Gaithersburg, MD

1. It's not a nfc, but everyone who guessed at my quiz, said I should
post here: http://trash-birder.blogspot.com/2010/03/mystery-sonogram-1.html.
Cliff notes: Try and guess the bird from the sonogram first and if you
can't do that, guess from the sound file linked below it.

2. Spring migration on the east coast.   Is there less interest in
spring nfc than fall nfc on the east coast?   It seems that there are
probably fewer birds; however, the night air in March and April should
be much "cleaner" without all the insect noise.  Are there any other
interesting differences between spring and fall nfc?

3. When do the sparrows start migrating in the spring?  With the
winter that we've had, it's hard to tell if the birds from Jan and
early Feb died, decided to move further south, or have already
departed to the north.

QuickTime will work on Vista as well as windows 7. Did you download  
the latest greatest? What type of sound files are you working with so  
we can recomend a better program for playback and analysis? What

I have just set up the Old Bird recording device and have begun to monitor
the skies over Southern California for nighttime flight calls.  Since it is
spring this is a migratory research project.  I am posting this to see if
anyone else has attempted to record the migratory patterns along the western
coastal region.  My listening station (my home) is in Laguna Beach, CA about
5 blocks from the beach.  I am interested in hearing from anyone with
information or interest in this area of study.

Winds (E/SE  AT  3-5 mph)last night were finally out of a different 
direction than North for first time in many weeks. Only a few birds 
between 12 and 5 AM (2 Killdeer, 3 Song Sparrow and a possible Wood 
Duck) but it was good night to shake the cobwebs off the recording 
equipment and make sure everything is in working order.

I also got a new computer over the winter and am pleased with the 
increased speed at which I can scroll through a sound file with 
Ravenlite. As call volume increases towards May, I switch over to using 
the Tseep/Thrush and Glassofire software. But when nights are not too 
busy, there's something enjoyable about scrolling through a sound file 
minute by minute looking for calls. Kinda of like going birding on your 
computer.

I noticed that Sony has a new flash recorder out that has good capacity 
and battery life (as it relates to recording time). The Sony PCM-M10. 
Anybody used one of these for night recording? I am thinking of 
upgrading my Sony minidisc recorder.

Folks,

I think this post may kick off the season for night flight calls in the 2010 
spring migration. Forgive me if I have missed a post or two. 


While sitting outside here in San Diego a little while ago, I heard the flight 
call of a Long-billed Dowitcher overhead, which I recognized immediately. There 
aren't really any good spots in the immediate vicinity where this species would 
transit between in a normal situation, so I believe it would constitute an 
early Spring migrant, which I believe starts in late February for this bird in 
these parts. I am about 10 miles inland from the Pacific Ocean.

Hi, all.

Say, I'll be talking about "nocturnal ornithology" at the 18th annual
Massachusetts Birders Meeting, sponsored by Mass Audubon, this coming
Saturday, March 6th. Here are abstracts for the entire program:
http://www.massaudubon.org/PDF/birders_meeting/2010/abstracts.pdf. Maybe
see a few of you up there?

And, then, the following week, I'm giving a similar presentation *at a
casino*. Who'da thunk? Details, sorta: http://tiny.cc/Vzurj

All, 


I have the impression that Blue Grosbeak and Passerina buntings are sexually 
dimorphic in their flight calls, higher pitched in females, lower in males, but 
have never tested this in any rigorous way. Has anyone else looked into this?

Subject: [nfc-l] passerines with sexually dimorphic flight calls? 

Equally interesting is the question of which passerines (and 'near-passerines') 
can be sexed according to their flight calls outside of the breeding season. I 
have not searched for examples in any thorough way, although I have been 
recording migrants and noting sex when possible for a long time, without 
noticing examples. 



During spring migration, some birds may sing while passing overhead, and 
depending on the species, this might be limited to males. Limiting the 
discussion to flight calls, however, I can only think of Raven as a passerine 
known to have at least some male- or female-only calls throughout the year. 



There are many more examples among non-passerines, eg Apus swifts, but most 
passerines seem to share non-breeding call repertoire across the sexes without 
noticeable differences. 



I would be delighted to be shot down and shown that there are many examples, 
but what are they? Alternatively, are there instances of some passerine species 
where males use certain shared calls much more often than females outside the 
breeding season? 



all the best, 


Magnus Robb

Without thinking too hard,UK birds which can be aged as 1CY-2CY or adult
using calls include Guillemot, sterna Terns, Herring Gull,
LesserBlack-backed Gull, Chiffchaff and Linnet. I'm sure further thought
would throw up more examples.

Hi all,
Ah, the interesting directions to pursue!  Great thoughts, Gerard,
Magnus, and Ross!

Two thoughts/observations:
- first, Rose-breasted Grosbeaks produce calls that vary by age, and
it's likely that other species might as well.  For grosbeaks, these
seem to coincide with discrete call types that differ rather
noticeably (by spectrogram and by ear) from one another in duration,
frequency, and note structure between juveniles and adults (in diurnal
and nocturnal migration) . . .

- second, during my dissertation research and in collaboration with
Mike, Emma, Lewis, and the Powdermill Avian Research Center folks, I
found that there were subtle but statistically significant differences
in various call measurements by age and sex in some species of Parulid
warblers; these data come from recordings of captive birds (a la
Lanzone et al. 2009 in the July issue of Auk), so whether this has
practical or biological relevance or application remains to be seen
(we're talking potentially highly esoteric subtlety in the machine
learning/statistical sense rather than subtle but clearly audible
difference typical of some species' complexes to trained field
observers).  I suspect that this subtlety, no matter how you describe
it, would be mostly lost in the typical types of recordings that we
make of passing, vocal nocturnal migrants - so, I won't be the one to
shoot down Magnus!!!

Regardless, I hope to publish this warbler work at some point in 2010
or 2011, but I can make available the chapter to those interested. . .

Best,
Andrew

It’s bordering on pure speculation and is only just relevant to this
group, but I have a sneaky suspicion the alarm calls of Blackbird are
sexually dimorphic. I’m collecting recordings at the moment to find
out.

Subject: [nfc-l] passerines with sexually dimorphic flight calls?
- Hide quoted text -

Equally interesting is the question of which passerines (and
'near-passerines') can be sexed according to their flight calls
outside of the breeding season. I have not searched for examples in
any thorough way, although I have been recording migrants and noting
sex when possible for a long time, without noticing examples. During
spring migration, some birds may sing while passing overhead, and
depending on the species, this might be limited to males. Limiting the
discussion to flight calls, however, I can only think of Raven as a
passerine known to have at least some male- or female-only calls
throughout the year.  There are many more examples among
non-passerines, eg Apus swifts, but most passerines seem to share
non-breeding call repertoire across the sexes without noticeable
differences.

I would be delighted to be shot down and shown that there are many
examples, but what are they? Alternatively, are there instances of
some passerine species where males use certain shared calls much more
often than females outside the breeding season?
all the best,

Magnus Robb

Good morning all,
I hope this message finds everyone well.  It's been a good inaugural year on
the NFC listserv, and personally I am looking forward to more in depth
discussion in 2010 (and beyond)!

I was thinking about the coming months, and the dearth of posting and
potential posting on the NFC listserv, and I thought a call to action might
be in order! So. . .although most of what we consider to be traditional
nocturnal migration of passerines is on pause for the moment (and note I say
traditional because plenty of interesting facultative nocturnal behaviors
can and will still occur in many places as can nocturnal movements of
waterbird, etc.), there's still some good flight call investigation and
consideration to be done: in particular, recording/listening to flight calls
on non-breeding and wintering territories and post-breeding family groups
(depending on your hemisphere!).  If any of you have the opportunity to
monitor or to record flight calls outside the typical bounds of migration,
and you make recordings or observations, please let us know and post on the
listserv!  Even the most basic reports of where and when you hear calls, in
what scenarios, etc., is invaluable!  There is much we still don't know
about extra-migratory situations in which flight calls are given, what
variation may exist among calls given in migration, non-breeding, and
post-breeding seasons, and on and on - so many threads to follow!

Just a thought.

Regards and all the best for a happy and healthy 2010,
Andrew

I have no doubt that is a Purple Finch. They give that slightly less emphatic 
pik when they are stationary compared to in flight.

Recorded SE Pennsylvania around dawn on Monday.
1 bird in flight
My guess is that the bird was smaller than a American Robin.

There was either a single call or two paired together as shown in the
attached jpeg.

Duration < 20 ms, which is much much shorter than sparrows.  I ran
through everything else that I could think of that would reasonably be
flying around (I was hoping for American Pipit, but that didn't
match.)

Frequency was in between 3-4 kHz.

Caitlin,

I agree with Chris, this sounds like a classic White-throated Sparrow call 
note that I hear frequently in my banding area pre- and post-dawn during 
migration.

Hello All,
Following a conversation with the Listowner, I would like to suggest that
when posting sound clips for ID or discussion, that we might all include a
brief description of our recording setup along with the date, time, and
location that the recording was made.

This could  be a good lead-in to the spring migration season, which will
be here before we know it!

Caitlin,

This sounds and looks like (in Raven Pro) a classic White-throated 
Sparrow flight call. Was this diurnal or nocturnal? They produce this 
same or very similar call on the ground during the day as they do at 
night in flight during migration.

Hope this helps!

Sincerely,
Chris T-H

This is rather ironic.   After asking for Savannah files and never
hearing more than one or two at a time, this morning the only sparrow
in large numbers ended up being a 30+ flock of Savannah Sparrows.  Now
I have tons of visually confirmed Savannah flight calls.
(Completely gone over the last week were the huge numbers of Song and
Swamp.)

I also recorded FOY Meadowlark (3) and am trying to figure out what
was rooting around in the 6ft grasses right next to me.  (Best guess
is a pig or a pheasant...short grunting noises.)

Lastly, right at dawn, I recorded a loose flock of smaller birds (I
believe smaller than Blackbirds/Starlings).  I can't match the flight
calls to anything and tried to attach the file but my message got
bounced back.

The calls are at 6-8 kHZ, somewhat burry, often double notes.

Sincerely,
Andrew Albright

Savannah Sparrows were very common nocturnal migrants when I worked for 
bioacoustics at Powdermill in 2007.� I sorted many hundreds from the recordings 
on the mics.� The stopover habitat for this species was marginal at that site, 
and as I recall, they only band a handful each fall.� I'm sure Mike can comment 
further.� It really underscores the ability of nocturnal flight call research 
to demonstrate the magnitude of flights that actually pass through an area.

A chilly hour and a half starting at 8:00 from the observation deck of the 
Empire State Building was as always an extraordinary experience. Though 
migrants didn't seem as thick as the last two nights, in the time we were up 
there, Lila Fried and I noted about 35 or so birds, mostly passerines moving 
southeast. A few did move southwest, and 1 robin was struggling against the 
wind moving northwest. Most birds passed over high, at the level of the needle 
of the building or above, though several passed by just above eye level. 
Amongst the mostly un IDable birds, the species we were able to ID included 
several American Robins, 3 American Woodcocks, 2 Great Blue Herons, 3 Catharus 
sp., and 1 Emberizid sp. As most birds were high, and somewhat distant, we 
didn't hear any flight notes over the other noise. 


Though things seem to be slowing down, there're still migrants to look forward 
to!

Tonight is looking good for much of the US, especially the Eastern flyway,
West North Central, Gulf region, and Florida
Here is the winds aloft forecast for tonight:

Some of you have already received this, but I figured it should go out to
the group as well. Sorry for any duplication!

-DLP

Hello Migration Enthusiasts,

As we approach the November 2nd full moon, we also begin the final
moonwatching event for the fall of 2009. Last month we had over a dozen
participants who contributed their data for a total of seven nights of
moonwatching. This month we hope to double that number, despite the colder
temperatures! You can find all of the information on this project, including
the forms you'll need for recording your data, on our website:
http://www.woodcreeper.com/moonwatching-2009/
If you are planning to do some moonwatching, please send me (
david AT woodcreeper.com) an email with your name and location so I can keep a
rough count.

Good Birding, and thanks for participating!

1) To me the flight calls sounded the same.   I did a doubletake when
listening to them and watching the sonagram (attached).

2) My best guess for the first one is Song Sparrow. I see one little
trill a lot with Song Sparrows so this is a bit different.  But, I
think this is the best match of the sparrows.

3) I would also guess Song Sparrow here too, although it too is a bit
non-standard.

I would interested to see what others say for IDs.

Sincerely,
Andrew

I was recording sparrow flight calls this morning and I'd like to turn
this into a quiz.

There are two flight calls in the attached file, presumably
sparrow(s). Recorded in grasslands/edge habitat this morning around
dawn in SE Pennsylvania.

Without looking at the sonagrams:

1) Do the flight calls sound
A) Same
B) Different

2) What is your ID of the first flight call

3) What is your ID of the second flight call


When/if there are 5 guesses or sometime this weekend I will post the
sonagrams for discussion.

Andrew,

I looked at some BB Plover calls at Xeno-Canto. None of Xeno-Canto BB 
Plover calls (measured at top of initial hook) were below about 2.8 Khz.

Looked at BB Plover calls at Cornell Library of Sound too but find 
Ravenviewer a little frustrating. My mouse pointer does not seem to 
calibrate with frequency shown on screen so its difficult to accurately 
assess the calls.

One of calls at Library of Sound (#3027) measures at 2.68 on 
Ravenviewer. Looks like the error on my screen is about + 0.24 when the 
upper freq limit is set at 5 Khz. This puts it a little bit closer to 
frequency of bird you recorded.

I have a possible Wood Duck call, recorded at night last May, I can send 
if you want.

Thank you Chris for posting the cut-down.

Does anyone like Wood Duck?     There are ducks in the area flying
around pre-dawn and this morning they sounded similar.  I listened to
Stokes' and there is a single call that sounds similar (i can't seem
to load it though to analyze the sonagram).  The ML's wood duck
collection shows a wide variety of frequency and types of calls for
Wood Duck.

p.s. Black-bellied Plover was selected which is a good match for
quality and sonagram. Stokes' recording is a bit higher frequency than
my recording.  Does frequency change with distance or echo?   ML
doesn't have much audio for Black-bellied Plover, but what is does
have is a fairly similar.

From pre-dawn, so I don't necessarily know it is a flight call.

I've gone all the way through Stokes and Lang CD's and I can't find
any matches and it doesn't ring any bells beyond Sora (which it
doesn't match).  A couple of shorebirds started to vaguely sound
similar, but not close.

I can send an mp3 (~2 MB) to anyone that wants to listen.

Well. I've listened to all of the wader recordings on Vogelstimmen and can't
match it up to any. One that got away I feel. 

 

It's gonna realty bug me for the nest few days though.

Hi Lee 

 

I've not ruled anything out yet, although Stone Curlew was not on my
immediate radar, but possibly a good call - I'll have a listen to the
recordings I have right now. 

 

I'm going through the Vogelstimmen set track by track at the moment, but i
have started with the Scolopacidae and I will widen my search if I don't
find it there.

 

Lee, please give me a call if you wish to discuss

 

Mike

Presumably you've ruled out STONE CURLEW - these birds are on the move right
now although Nottinghamshire is a little way north of their migratory route.

 

Best wishes

Hi All

 

I've just stepped outside (2335 BST) and heard a all call going north that
i've never heard before. I would transcribe this call as "whooodleee" where
the "...dlee" part is at least an octave above the "whooo..." part, and
rising in pitch.

 

I've never heard this call before and i am now going through all of my
recordings to see if i can match it. The call was certainly more Wader
(Shorebird) than Passerine.

 

If anyone has any suggestions please post (cc'ing all 3 groups). 

 

If i match the call, i will of course post.

 

Thanks 

 

Mike

Hi All,

Much further south at the southern tip of Jekyll Island, Georgia (about 25
miles north of the Florida state line), I also had a very heavy migration
night with 140 calls per minute between 6am and 6:45am this morning.
Dominant species seemed to be Swainson's Thrushes and Palm Warblers but also
included were presumed Indigo Buntings (I don't know the flight call of
Painted Buntings of which there are quite a few here), Bobolinks,
and probably American Redstarts and Common Yellowthroats.  Quite a few
Savannah Sparrows and at least one Grey-cheeked Thrush.  Many unidentified
chips though.  The wind was from the NNE at about 5 mph which was a first
since the ridiculous heat and humidity and south winds of the last three
days.

What Jeff heard matches almost exactly in composition what I heard along
Delaware Bay 10 miles north of Cape May from 5 to 6 a.m., although when I
averaged call numbers for the hour it came out to 5-6/minute for the entire
time. There were spurts of much more calling.  I also heard 7 American
Bitterns, Gray-cheekeds, the first few Hermit Thrushes of fall, and a few
other things.  

 

Does anyone use, or is anyone aware of, a scale turning calls-per-minute
into qualitative terms like light, moderate, and heavy migration?  This
would be site-specific, of course, but I'm curious what other people
consider a heavy migration night.

This morning, around 2am, while listening to migrants, I heard an
unfamiliar "ehk" sound, somewhat like a shortened duck quack. The bird
called repeatedly while flying SW. I know this a horrible description, but
I was just wondering if anyone would know what this bird was. 

This morning I also heard: 

American Bittern-really low, calling loudly
Chipping Sparrow 
Field Sparrow 
Song Sparrow 
Savannah Sparrow 
Dark-eyed Junco 
Veery 
Swainson's Thrush 
Hermit Thrush  
Yellow-rumped Warbler


Thanks,

Looking quickly at your image, the latter call looks like a classic 
Black-throated Blue Warbler.

Good night listening!

Not really about nocturnal sounds but I did a little essay comparing
songs and showing sonograms of Yellow Warblers from Yellowknife, NWT
with Yellow and Chestnut-sided from Maine that some of you may find fun
and interesting at:
http://www.borealbirds.org/blog/?p=186

I haven't tallied calls registered from last night's flight but it was
certainly booming before midnight when I went to bed.

A lot of us in Cape May had written off a night flight since the winds were
forecast to go south overnight, and they did. I wasn't out listening in the
dark, but there was a good morning flight at Higbee Beach heading straight
into the wind (going south instead of the usual northbound morning flight).
Doug Gochfeld counted 8,997 birds. I summarized the mix at

Hey All- I just checked the radar and it looks like a pretty heavy flight over 
the Northeast US, the northern tier of the middle-states (northern Central and 
Mississippi Flyways) and the Southeast (especially the Southeast!). Is there 
anyone out listening tonight? The skies are pretty cloudy here in NJ, but the

3-4 October, the Fortaleza of Sagres, the southwest corner of Europe,  
and the last point of land for many migrants flying towards Africa.  
Full moon, a light (force 3) northwest wind, and some thin, wispy cloud.

 From about 45 minutes after sunset, I started hearing European  
Robins calling seep as they flew over the floodlit fortress and out  
over the sea towards Africa. This was something new for me. Only once  
before had I managed to convince myself I was hearing a Robin  
migrating at night (in Zeeland, the Netherands). Now, between 19:45  
and 23:30, and from 05:00 to 07:15 the next morning, I heard about  
80! In among them were also 6 Pied Flycatchers, 5 Ortolans, 1 Corn  
Bunting, 1 Common Sandpiper and 1 Common Ringed Plover, not to  
mention a good few UFOs.

The Pied Flycatchers were particularly exciting for me, as I�m not  
aware of any previous claims of this species migrating audibly at  
night. Spotted Flycatchers have sometimes been identified elsewhere,  
which suggested to me that Pied should be possible, and I�d been  
listening out for them. The call I'm hearing is not the better known  
wit call (though I did hear this once), or the very short, sharp tak,  
but a high-pitched, buzzing call very similar to one used frequently  
by resting migrants during daytime. I need to take a closer look at  
the contexts in which they use this call, but I have the impression  
that it is mainly during encounters with rivals (Pied Flycatchers  
defend feeding territories during their migration stopovers in  
Portugal). Because this is so new, and I'm not sure how different  
Spotted Flycatchers sound at night, its probably best to regard these  
as probables, but I�m pretty sure the majority of the 6 were Pied.

Of the Ortolans, two gave multiple calls (with a variety of typical  
Ortolan sounds), and three just a single call, so the latter are  
perhaps also best regarded as probables. The Corn Bunting gave a  
whole series of unmistakeable flight calls as it flew over in the dark.

The two following nights sounded almost birdless, perhaps because of  
clear skies on one and a southeasterly headwind on the other. Or  
because of poor weather further north, and the supply of new migrants  
running dry. I still have much to learn about the right conditions  
for hearing nfcs here, but at least now I've experienced one really  
good night.

bye for now,

Magnus Robb

I'd be interested in hearing what types of recordings other people are
making and being able to more easily share what I've recorded.

Does anyone have an easy way to post files of reasonable size, say
less than 10 MB...that should be nothing these days?

For example, I recorded last night and assembled a collage of three
<1minute segments of nfc from midnight to 5:50am. And with the colder
nights and weather conditions, I'm starting to get better recordings.
Even had a small flock of double-down seeps (Savanah Sparrows?) - see
attached sonagram.

Sincerely,
Andrew

I just got in from an hour of moonwatching with Brian Clough, where we
counted 62 birds between 8:55pm and 10:25pm (we counted over six ten-minute
periods between those two times). There were many birds calling overhead,
but neither of us could get beyond "sparrow-like" and "warbler-like". No
thrushes were heard (again, untrained ears could be to blame).

Activity is still hot and heavy in the NE and Mid-Atlantic... so get out
there if you've got the time/motivation!

Good Birding

NFC Group,

Last week, when I had the 100+ Swainson's Thrushes before dawn*, I had
very few other flight calls detected.

Here is one upsweep "stip" or "seep" (attached), that I can't seem to
find in the Evans/O'Brien flight call guide, my best guess is
Black-throated Blue Warbler.

1. 32ms  (seems shorter than most)
2. Starts at 6.8-7.3 kHz and ends at 7.6-8.0 kHz with a plateau shape.
(There's the obvious caveat my recording equipment might be missing
some audio and the frequency incorrect.)

I'll try a followup email with the sound file, if not I can email it to anyone.

Sincerely,
Andrew Albright

2 questions.

1) Are some nocturnal migrants small enough and high enough (on certain 
nights) that you would miss seeing them pass in front of moon even with 
a scope? I know how small a migrating Broad-winged Hawk can look at 
midday when they pass over at high altitude.

2) My eye gets "harshed out" a bit from moonwatching through a scope. 
Does anyone use a camera filter of some type when moonwatching for long 
periods of time? I know my Swarovski 65 can supposedly take a 67mm filter.

Thanks for advice,

Andy Martin

Hey All

We (Mike Lanzone, Andrew Farnsworth and I) are attempting to pull together a
nationwide moonwatching event beginning tomorrow night and continuing
through next week. We have come up with some protocols, borrowed from the
work of many others and modified to suit our needs, and posted them on the
following webpage: http://www.woodcreeper.com/moonwatching-2009/

We welcome any and all of you to participate in the event. Prior experience
is not required, we only ask that you follow the protocols outlined on the
site, and enter and submit the data according to the instructions on the
site and within the Excel spreadsheet. Once you read over the materials, if
you still have questions, please feel free to email me and I will try to get
back to you as soon as possible. This is also a great opportunity for folks
to get together with other birders (or astronomers!) and coordinate a
meet-up. I encourage anyone considering joining the party, to send out an
email to their local listserve and see who might be interested in joining
you for a night or two of moonwatching. Moonwatching and recording data is
always easier when you can switch off with another person.

Looking at the weather, on Friday night the Central Flyway should experience
the first NW winds which should, in turn, trigger the next migration event.
This system will move east over the weekend, setting up migration conditions
over the Mississippi and Eastern flyways in successive nights (maybe not
until Mon or Tue night for the Eastern Flyway, depending on which forecast
model you check).

The full moon is on Sunday, October 4th, so moonwatching conditions should
be excellent (assuming a clear sky) over the next 8 days.


Good Birding AND Moonwatching!

Jacob - COOL observations!

Yeah, the radar is really lighting up tonight! (here's 8:50pm:
http://tinyurl.com/yas9sum). So Mike Lanzone, Andrew Farnsworth, and myself,
triggered by Mike's impromptu moonwatching event last month, have decided to
coordinate a nationwide moonwatching event over several nights starting on
Friday.  After tonight, it looks like the winds will turn southerly again as
a strong low approaches from the west. On Friday night, though, the Central
Flyway should experience the first NW winds which should trigger the next
migration event. This system will move east over the weekend, setting up
migration conditions over the Mississippi and Eastern flyways in successive
nights (maybe not until Mon or Tue night for the Eastern Flyway, depending
on which forecast model you check).

The full moon is on Sunday, October 4th, so moonwatching conditions should
be excellent (assuming a clear sky) over the next 8 days.

If you're interested in participating, please email me and I'll begin
compiling a list. We're putting together a list of methods for the moonwatch
(no prior experience necessary!!), and a spreadsheet for entering the data
you collect. Please let me know in your response whether you have access to
Microsoft Excel or Google Spreadsheets (or another spreadsheet program).
This will determine which data sheet we send you.

Good Moon Watching,

David

Moonwatching from my aprtment (looking southeast up at moon) from 8:36 to 9:46 
produced a total of 58 UFOs (birds/bats/insects), 56 of which were all flying 
southish. Many were definitely IDable as birds, and 1 bird, low enough it was 
probably at around building level, and moving NW was almost definitely an 
American Robin. 1 bird was flying very high with fast direct flight, suggesting 
a waterbird (????). In general, flight patterns noted (included boyant 
passerine ones, as well as direct ones). When birds passed along edge of moon, 
this was much more difficult to tell. Some things did look distinctly like 
erratically flying bats, and one thing flew like a moth. Also of note, several 
small groups were noted, as a few birds passed the moon within close proximity. 
Being in an apartment, no vocalizations were heard. Is 58 birds in 1 hour a 
good flight? Mediocre? Poor? What number of sightings per hour signifies a good 
flight?

All

 

I live in semi-urban Nottinghamshire (UK) and regularly hear Fieldfare
calling at night during the major Redwing movements. Blackbird, Song Thrush
& Robin are also commonly heard and occasionally Ring Ouzel and Dunnock. I
rarely hear Mistle thrush at night, although I have done on a couple of
occasions. Not many other passerines are commonly heard on night migration
in the UK; mainly waders (shorebirds), ducks, rails and gulls. Just 10
minutes ago, I heard a Green Sandpiper calling as it flew over.

 

Still waiting for my first autumn Redwing this year - by my previous years
records, they are now late (usually heard first around the 26th Sept)
although I did have one calling at night on 30th July this year which I
suspect was a UK breeder rather than a Scandinavian migrant.

 

Cheers

 

Mike

Hello Magnus,

I was most surprised to read that nobody you've asked has ever heard
Fieldfare at night!? But I'd be interested to know if you've asked any Irish
birders? As a young birder growing up in the suburbs of Dublin Ireland
during the late seventies and eighties, I'm sure we'd occasionally hear
Fieldfares on migration at night, particularly when it was clear that there
was also a good push of Redwings taking place.  It wasn't common to hear
them- not as you would Blackbirds, Song Thrushes or Redwings. And you
wouldn't necessarily hear Fieldfares during good Redwing flights either. It
was a long time ago, and my memory might have me thinking that it happened
more frequently than it actually did. But I believe it was most definitely
AT NIGHT, that is, at least two or more hours after dark, and on a good
night with northeast winds you could hear a least two or three birds at
least. (Please keep in mind that I was not purposely "monitoring" migration-
frequency and/or time of night and certainly not listening throughout the
night). My main point here is that it was taken for granted that you
could/would hear Fieldfares at night? I'm sure I recall other birders
commenting that they had heard them. Am I totally mistaken somehow? As I
remember, the call was a short dry "chack" I think, which might have been
repeated somehow like "chack-chack-chack" or such, I honestly can't remember
exactly, but it was pretty distinctive. I'm tempted to think whether the
birds might have called arriving over the lighted streets having just
crossed the Irish Sea? But the UK is littered with coastal cities not just
the Republic of Ireland, so I'm genuinely surprised and a bit bewildered? 

My house was about a 15 minute walk from the north Bull Island in Dublin
Bay. I could sometimes hear shorebirds in bed at night, mostly Redshanks and
Curlew but also the occasional Dunlin, Oystercatcher, Greenshank and one or
two Green Sandpiper over the years I think, and flocks of Brant and the odd
Wigeon- but it's all late seventies and the eighties I'm thinking of. Nobody
I knew kept notes on night migration.

BTW, I very much enjoy your Petrels book!

Cheers,

Gerard Phillips

Hi Mike,

At this time of year in much of the UK, Song Thrushes should still be the
dominant thrush, but Blackbirds and Redwings will be starting to join them.
With a lot of luck you might hear a Ring Ouzel, but this is not a common
thrush. Oddly enough, Mistle Thrush and Fieldfare don't seem to call much at
night. Nobody I've asked has ever head more than the odd call at dusk or
dawn, even at times when many were moving through. Has anyone in this group
heard them at night? 

As for other passerines, relatively few European ones seem to use flight
calls at night, which partly explains the relative lack of interest in night
flight calls over here. Most of what you hear comes from the three species
of thrush I mentioned first. Among the passerines I've definitely heard
flying over at night are: Skylark, Woodlark, Tree Pipit, Snow Bunting and
Ortolan. A Willow Warbler at night sounds unlikely, as none of our warblers
call much in flight (except Cisticolas). Did you get a recording?

I live in Portugal where there are huge numbers of Pied Flycatchers passing
through just now. I've been out several nights trying to find out whether
they have nocturnal flight calls, but so far without any conclusive results.
What I have learned however is that I am hearing a few passerine flight
calls that I can't yet identify. I have a good knowledge of the calls of
most western European species by day, so perhaps some are using different
calls at night that I've simply never heard. In short, lots to learn for us
Europeans too! 

Besides passerines, you are of course likely to hear lots of shorebirds, and
geese as the autumn progresses. Which species you hear will depend very much
on where you are. 

Feel free to send me some of your UFO recordings. I'm keen to puzzle and
learn about what else is flying over at night... 

cheers,

Magnus Robb

Hi all,

Last night I heard my first flight calling overseas. Currently I am in
Chester, England and had a decent number of migrants this morning. Not sure
what to expect for numbers  here, but I was hearing 8-10 thrushes per minute
during the peak, typically less though. I am guessing Song/mistle Thrush,
also had what sounded like Willow Warbler, many unknown. Will need to learn
more night flight calls here! Had a number of shorebirds pass over as well,
greenshank, lapwing, redshank, green sandpiper?, golden plover, etc. Looking
forwrd to the next several weeks in Europe! Any advice from any of you as to
what you are hearing this time of year? I will be mostly in UK for the next
week, then spending most the rest of my time in France, Germany,
Switzerland, Italy. I also hope to spend some time in the alps listening to
nocturnal migration, possibly col de bretolet. Anyway, be interestd in what
to expect and some sample calls if any of you have them to share! I am doing
some recording so will hopefully have something good to share as well.

Talk to you all soon,
Mike

Michael, Jeff Wells, and other radar enthusiasts,
For British Isles radar data, you can check the UK Met Office website here:
http://www.metoffice.gov.uk/weather/uk/radar/index.html

By clicking on the radar locations, you can see the local radar scans rather 
than the composite radar image for the UK. This is where I would look to find 
radar imagery, but having never lived in the UK or had much need for looking at 
radar imagery in that country, I am not familiar with many of their radar 
websites. 


Some of their radar sites are Doppler radars. For a complete list check on page 
ten of this UK Met Office Radar document: 

http://www.metoffice.gov.uk/corporate/library/factsheets/factsheet15.pdf

The problem with looking at these radar images is that they are filtered by the 
Met Office to remove "ground clutter". This is often the same range of 
reflectivity where birds show up, so they are likely removed from the imagery 
displayed on the web. It is specifically stated in their fact sheet that 
drizzle often isn't seen on their radar imagery, this usually means that most 
birds are not going to show up on their radar imagery (that is displayed on the 
web). 


On a slightly different topic, ever since Jeff Wells emailed this list 
wondering where to get radar imagery for other locations in the world aside 
from the US, I have been trying to track down all the radar locations for the 
globe and plot them in Google Earth. Being able to find the radar locations is 
one thing, but finding the radar imagery that is real-time and readily 
available on the net for those sites can be impossible in some instances. 
African radars are notorious for this, because there isn't enough money, parts, 
and know-how to repair the radars if anything goes wrong with them. 


You may wonder why I am only plotting the locations of the radars. I am only 
plotting locations, because I was hoping the community might be able to help 
find the radar imagery sources. Not being familiar with each country's weather 
service makes it hard to find images, and not every country has a weather 
service either which makes it even harder to find the images in some instances. 
Other countries make their radar imagery available only to citizens accessing 
the imagery from that country. If anyone knows where to get radar imagery for 
the radars found in the Google Earth file, please let me know. I know currently 
where to get radar imagery for the US, the UK, Canada, South Korea, Australia, 
Israel, and Malta, with a few other leads. This is not yet the entire radar 
set, but I will be updating the file through time and hope I can come close to 
a complete dataset for the globe. 


Having said all this, it isn't clear that every country will have radar imagery 
that isn't filtered, so it might be like the UK imagery that tries to filter 
out the "clutter" (including birds). 


Here is a link to the radar locations file:

http://homes.comet.ucar.edu/~guarente/Google.Earth/Radar/Radar.Locations.Network.Link.kmz 


Open that file in Google Earth and you will see placemarks (thumbtacks) for all 
the radar ocations I have found, before I had real work impede my work flow on 
this side project. 


 
If you have any questions about Google Earth use, or radars, feel free to ask.
