[Andrew Farnsworth ] Subject: Re: Mystery Sonagram Quiz and Spring Migration questions/musings From: Andy Martin <apmartin2 AT comcast.net> Date: Mon, 15 Mar 2010 00:45:14 -0400 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.

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.

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.

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.

From: "Michael O'Brien" <tsweet AT comcast.net> Date: Sat, 19 Dec 2009 04:02:04 +0000 (UTC) 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? Michael O'Brien ----- Original Message ----- From: "Magnus Robb" To: "nfc-l AT cornell.edu Call ListServe" Cc: "Andrew Farnsworth" , "SLIMBIRD Gerard" Sent: Friday, December 18, 2009 12:04:22 PM GMT -05:00 US/Canada Eastern 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 On 18 Dec 2009, at 16:2324, SLIMBIRD Gerard wrote: A related discussion which I’m sure many on the list might be interested in learning more about in general is flight call variation of adult verses juvenile birds.

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!!!

From: Andrew Farnsworth <andrew.farnsworth AT gmail.com> Date: Thu, 17 Dec 2009 10:48:04 -0500 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.

From: Andrew Albright <andrew.albright AT gmail.com> Date: Thu, 5 Nov 2009 20:59:42 -0500 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.

From: Ben Coulter <anax_longipes AT yahoo.com> Date: Wed, 4 Nov 2009 08:14:27 -0800 (PST) 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.

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.

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.

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.

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.

From: "Mike Feely" <mike.feely AT btinternet.com> Date: Fri, 16 Oct 2009 23:35:06 +0100 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.

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.

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 -- NFC-L List Info: http://www.NortheastBirding.com/NFC_WELCOME http://www.NortheastBirding.com/NFC_RULES Archives: 1) http://www.mail-archive.com/nfc-l AT cornell.edu/maillist.html 2) http://birdingonthe.net/mailinglists/NFCL.html 3) http://www.surfbirds.com/birdingmail/Group/NFC-L Please submit your observations to eBird: http://ebird.org/content/ebird/ -- Subject: Sharing sound files?

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).

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.)

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! Andrew Farnsworth Michael Lanzone David La Puma For a great study using moonwatching, you can read Lowery and Newman's 1966 paper A CONTINENTWIDE VIEW OF BIRD MIGRATION ON FOUR NIGHTS IN OCTOBER published in The Auk, and download-able as a pdf here: http://elibrary.unm.edu/sora/Auk/v083n04/p0547-p0586.pdf ____________________________________________________ David A.

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.

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.

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!

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 On 27 Sep 2009, at 22:1501, Michael Lanzone wrote: Hi all, Last night I heard my first flight calling overseas.

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.

I'm very interested to read that you heard Fieldfares, and have no reason to doubt it. I've always thought that I 'should' hear them at night, and was surprised that I didn't. One thing that may be of interest is that Fieldfare and Mistle Thrush, the other species I've not been hearing at night, are the two thrushes with the lowest-pitched flight calls. Redwing, Blackbird and Song Thrush have high-pitched flight calls, not unlike many of the zips of NA wood warblers and sparrows. So perhaps Fieldfare and MT are less 'into' nocturnal migration, and have not evolved such specialized flight calls. On the other hand, when I lived in Holland I sometimes saw them coming in off the sea in the morning, so they presumably crossed the North Sea at night. cheers, Magnus On 29 Sep 2009, at 15:2716, SLIMBIRD Gerard wrote: > Hello Magnus, > > I was most surprised to read that nobody you’ve asked has ever > heard Fieldfare at night!?

Thanks to Matt Hafner for these great observations from Florida. > Has anyone else heard a large predawn flight with such a lack > of diversity? Most of my listening has been inland in the mid-Atlantic > and while I've had plenty of thrush-dominated mornings, I've never > had a single species compose so much of the calls. Gimme a few months, please, and I'll be able to post a quantitative summary for July-November for Boulder County, Colorado, 2007-2009. In late July and early August, when we have decent flights (30+ flight calls per hour), they are dominated by Chipping Sparrows. I'd say 80-100% of the flight calls are given by Chipping Sparrows on those nights with decent flights; by mid-August, diversity increases. These lateJuly/earlyAugust flights are full-on, sustained, middle-of-the-night flights of birds on active nocturnal migration. (Cf. ongoing discussion about the definition of night; and "old-timers" may recall that we discussed zugunruhe vis-a-vis actual nocturnal migration, way back in the old days of August 2009!) Here's something to ponder. I'm certain that warbler/sparrow calls are going to be more than 90% of all flight calls, in the final analysis here in Colorado. Probably more than 95% of all flight calls. The total number of thrush calls is going to be less than 1%, and perhaps down around 0.1%. In contrast, y'all Back East have experiences like this: thousands of thrushes; a decent smattering of grosbeaks, tanagers, and Bobolinks; and 1 or 2 sparrow notes. (There have been several such postings to NFC-L in the past month; seriously, *one or two* sparrow/warbler flight calls amid literally thousands of flight calls of larger species.) Here in Colorado, again, the warbler/sparrow notes are dominant, overwhelmingly so. I've been out most nights the past 2 weeks, and I've heard absolutely nothing but warblers and sparrows. The IDs are provisional, but most seem to be Orange-crowned and Yellow-rumped Warblers, plus Chipping, White-crowned, and Lincoln's Sparrows. Mainly presumed Yellow-rumps and White-crowns. Believe me, if I heard a thrush or Bobolink, or just a wimpy Western Tanager, I'd jump out of my pants. Best, Ted Ted Floyd tfloyd AT aba.org Lafayette, Boulder County, Colorado P.s. I'm talking about fall in Colorado. In spring, we get Swainson's Thrushes, Bobolinks, grosbeaks, buntings, all that good stuff. -- NFC-L List Info: http://www.NortheastBirding.com/NFC_WELCOME http://www.NortheastBirding.com/NFC_RULES Archives: 1) http://www.mail-archive.com/nfc-l AT cornell.edu/maillist.html 2) http://birdingonthe.net/mailinglists/NFCL.html 3) http://www.surfbirds.com/birdingmail/Group/NFC-L Please submit your observations to eBird: http://ebird.org/content/ebird/ -- Subject: Re: UK flight calling From: SLIMBIRD Gerard <gphillips AT istar.ca> Date: Tue, 29 Sep 2009 10:27:16 -0400 Hello Magnus, I was most surprised to read that nobody you¹ve asked has ever heard Fieldfare at night!?

Nobody I knew kept notes on night migration. BTW, I very much enjoy your Petrels book!

Around 3:30am, I recorded this two-syllable bird flight note. Now, had I been birding in mid-June during the daytime and heard this, I might have passed it off as a Baltimore Oriole. But, this sound was produced in late September at night. Could this really be a Baltimore Oriole? Other suggestions are welcome. This clip has had the LF noise and a couple bands of cricket noise filtered out.

Some of you were wondering when specifically I listened, well, last night between 2- 2:30am and then again 5-6am, however I think it was too breezy here and I did not hear anything at all. But the night before when there was some calling activity I listened some at about 3am and then heard mostly shorebirds plus some unknown spp. I then listened between about 5:30 and and 6:30 am, it was still dark out, have not civil twilight was 6:50. I heard most of the calling in this period. Some calls were either Song or Mistle Thrush not sure which, I am wondering now if they really move nocturnally much at all though. From my observations of both species the last several days, in habit they seem very similar to our American Robin, which will sometimes move pre-dawn, most of the time they move early am though and will vocalize heavily sometimes in the hour before sunrise. The vocalizations I heard were similar to song/mistle flight notes I heard while observing these spp. here the last several mornings. The Willow Warbler ID was purely a guess, but it sounded virtually identical to the call I heard in the field that day and was fairly close overhead. A single rising "tuwee", but as I found out today Chiffchaff have a similar call to this too which they do give in flight. I was also curious about this as I had heard sylvids did not call at all at night, and it could be that the call I heard was from some other species all together that I am not familiar with. Much to learn for sure, that is why I am so excited to be here and have the opportunity to listen a bit while I am here! I did not get any recordings yet as I failed to bring the right UK converter for my computer, but I got one today! I will be traveling to Scotland tomorrow for about 5 days before working my way over to the Swiss/Italian alps to do some recording in mountain passes there, should be interesting! I will let all of you know what I find/record. I would be interested to hear more from others with there observation over here too! On a side note, I noticed over here there seems not to be very good radar coverage. It could just be that I am not finding the right sites though, but I was looking for just simple reflectivity to gauge migration intensity vs what I was hearing. Is there doppler radar in Europe?

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 On 27 Sep 2009, at 22:1501, Michael Lanzone wrote: > Hi all, > > Last night I heard my first flight calling overseas.

We arrived at the Guana Lake Dam north of St. Augustine at 6:20am and stopped estimating "night flight calls" at 6:50am.? During this time, we estimated that Bobolinks were calling at a rate of 3-5/second.? At no point during this time were they calling at a rate of less than 1/second and 8+ calls/second were maintained for a few short periods.? As dawn broke, the calls dropped off significantly, but we observed several high flying flocks of Bobolinks throughout the morning and could often hear more while in the woods.? Bobolinks have been the dominant night flight call in this area for about 3 weeks now.? What was just as interesting to me as the number of Bobolinks were the lack of other species calling in the flight.? During the same time period we only heard: 4 Swainson's Thrush 1 Veery 1 Rose-breasted Grosbeak 1 Summer Tanager (presumed, I have little experience with this call) 2?presumed warbler?seeps We thought we might just be having a difficult time hearing other species over the Bobolinks and that may have been true with the warbler notes.? The thrush calls still stood out amongst the chorus. Has anyone else heard a?large predawn flight?with such a lack of diversity?? Most of my?listening has been inland in the mid-Atlantic and while I've had plenty of thrush-dominated mornings, I've never?had a single?species compose so much of the calls.? ?

From: Harry Lehto <hlehto AT utu.fi> Date: Mon, 28 Sep 2009 21:00:04 +0300 Dear all, thanks for all the input, references and answers. Yes, it is indeed quite clear in real life when night ends and it is good to see that the formal limits agree. In my parts of the country the first sign of the night getting to an end is a 1 hour chorus of pygmy owls, followed by (the proper) Robins and blackbirds. Around the start of blackbirds calls is where my local night appears to end. This is some 45 minutes before sunrise (twilight is somewhat longer at 60degN than say at 40degN). This definition is potentially problematic in late May when the last arctic migrants head for the tundra - there is almost no "proper night" at that time here. And slightly off the migration topic. This past June/July we intentionally birded in Lapland (70degN) with my son at "night time" because of lower levels of background noise for recording. Despite of the midnight Sun being above the horizon we were impressed how most of the birds were completely silent (slept) for the "darkest" 3-4 hours.

My first take is that this is not from a plover, certainly not from Black-bellied or Semipalmated. There is the possibility of a weird Golden perhaps but it is unlike any I've heard. It is reminiscent of Long-billed Curlew, but seems on the short side and like it came from a smaller bird, and of course you recorded it in Ohio so the odds are extremely low. Dropping down in size brings up the possibility of Whimbrel, but they don't give one-noted calls like this as far as I know -- still something resonant with Whimbrel for me. The other possibility to consider might be American Avocet. The call is a bit low and stretched out compared to typical calls this species gives when flushed to flight, but perhaps in night migration individual calls are softer and longer. Maybe folks on this listserv in western US would have a better sense for the possibility of Avocet. Final thought is the possibility of an extreme variant Sora. In any case, interesting call and I'd look forward to hearing comments from others.
