Heavy migration across mid-Atlantic

Clear skies and northeasterly winds made for a big night of nocturnal migration across the region. Here’s the radar from 7:00pm last night through 5:00am this morning.

High pressure across the Northeast and mid-Atlantic set the stage for optimal migration conditions last night. All radars (except the extreme northeastern US) showed heavy migration beginning just after sunset and continuing into the early morning hours. The local radars indicate a NE->SW trajectory, suggesting that the light northeast winds are pushing birds slightly west. This bodes well for inland fall migrant traps this morning, including the southern end of the Watchung Mountains (Chimney Rock) and locations along the north shore of the Delaware Bay. Fall migrant traps throughout Pennsylvania should also be good this morning as migration was heavy over the entire state.

Good Birding
