Songbirds migrate in the dark and last night was a busy one for them above Pennsylvania. At 2am national radar data showed them moving west-southwest across PA on their way to the Ohio Valley. (BirdCast screenshot above.)
By 5am they were getting ready to stop for the night. In the map below they appear to set down just inside western Pennsylvania. Woo hoo!
How good is my prediction that “birds arrived overnight?” I’ll let you know what I see today.
UPDATE AT 5PM: I went with friends to Moraine State Park from 9:30a-12:30p and saw 8 species of warblers, flycatchers, lots of cedar waxwings, Baltimore orioles, blue jays, chimney swifts, etc. Yay!
