Land bird migration, Nov 4th

Although more at work than birding, signs of passerine migration were obvious: flocks of American Robins at mid-altitude over Ewing after sunrise, more on the ground in Princeton, then more flocks headed south west over Princeton U. campus around 10:45, along with an icterid flock and a Cedar Waxwing flock. Two Golden-crowned Kinglets were feeding in the trees outside the lab.

Central Park Oct 23rd

Central Park was notable for a good push of late fall migrants: lots of Hermit Thrushes, Song Sparrows, Yellow-rumped Warblers with quite a few Ruby-crowned Kinglets and Gray Catbirds. The diversity was low - something that had something to do with me staying put in the Maintenance Field for a couple of hours watching the flocks of sparrows working their way through. The warbler count was fleshed out by a lone Magnolia (my new late date, and pushing it's luck) and one Palm Warbler. The usual late fall additions of Purple Finch and American Goldfinch were absent, presumably because of good crops in the north this fall and the consequent lack of an invasion year.
