Little to no migration (Updated)


I didn’t have time to post the radar early this morning morning, because, just as our newborn daughter entered the world, my alarm went off to tell me it was time to download the radar images (which is a loud chorus of Common Loons- so you can imagine how crazy it was to witness her birth at 5:14am, and then have the loons calling at 5:15… totally wild!). As I said this morning, it appeared that for the most part there was no migration last night. Only a little NW->SE movement could be seen over the Delmarva after the cold front passed. Here’s the radar from 7:00pm last night through 5:00am this morning.

Frames are every 1/2 hour. Click on the thumbnail to view the full-sized animation.

Winds on the eve of the cold front were from the south, which suggests that all the “good looking” signal over NJ yesterday evening was not birds (check the velocity- no birds would be heading due north). This could have been pollen, dust, etc, but surely not birds. As the front passes, some activity can be seen heading east behind the front. Is it birds? Maybe, some of it, but it’s hard to tell.

Making any birding conditions at this point would be like playing Monday morning quarterback, so I’ll refrain.

Good Birding

  1. Overall it was quiet at the C-Farm–but I saw a few notable birds incl. BOBOLINK (2+)–my latest record for CF; FIELD SPARROW (my earliest fall arrival for CF), and PRAIRIE WARBLER (scarce at CF–only my 2nd this year). Several White-throats around, Ind. Bunting, etc.
    Looking forward to tomorrow.

  2. Question: As predicted, yesterday was a great day here in Southeast Pennsylvania (just outside Phila). If there wasn’t any overnight warbler migration, then would we still have the same ones as yesterday?

    Or do they just migrate a little bit on “bad” migration nights?
