Little migration last night


There was very little migration apparent on the radar last night, all of which was from E–>W. Here’s the radar from sunset last night through 5:30am this morning.

Frames are every 1/2 hour for reflectivity and velocity, and every hour for the regional composite. Click on the thumbnail to view the full-sized animation.

Southeasterly flow appears to have kept most birds down over night, although the radar did pick up something moving across the radar from E–>W. The signal appears to be birds, so we’ll go with a tentative “light” migration for last night. Inland sites should be best given the circumstances, but my experience at Garret Mountain yesterday (after another such flight) was that birds were very patchily distributed. Flickers, Sapsuckers, Robins and White-throated Sparrows were the most dominant, with a smattering of warblers (HY Blackpolls, Black-and-whites, and a Nashville), R.C. Kinglets, and Swamp, Chipping, and Savannah Sparrows. FOS Dark-eyed Junco at the radio tower made my “day” (although I know they’ve been reported elsewhere already).

Good Birding
