I looked at a few of these animations, just for fun.
I checked species that have expanded their range like California Scrub Jay, Bewick's Wren, and Black Phoebe. I note that there seems to be more detections in December, probably CBC's.
I looked at Harris' Sparrow and Sprague's Pipit. They really make an explosive move north, flare big in the breeding season, then DISAPPEAR in late summer, before reappearing on their wintering grounds. Where are they in August - September? Where are the observers?
Surf scoters seem to disappear in the winter. What's with that?
Just a few things I noticed in a quick look around.

Thank you. The animated maps are very informative especially for someone (like me) who thinks a picture is worth a thousand words!!Jack WilliamsonWest Linn, Oregon
