The data are from eBird Gadgets, updated half-hourly and color-coded by ABA difficulty (1-5).
For multiple samebird-sameplace reports only the most recent observation is shown.
Both the markers and the map can be dragged with the mouse. The map can be panned and zoomed
with the controls in the upper left and the map style can be changed with the controls in the upper right.
Panning and zooming to a particular state can be done with the state codes beneath the map.
