Yesterday and today have been awesome in Philly for migration. The weather is not so good, bordering on awful but that isn't stopping the birds. The weather is preventing me from bringing the camera out, so you will have to look up the following list in your bird guide to see what they look like.
Lemon Hill has been really good with many species of warbler including Redstart, Magnolia, Nashville, Ovenbird, Black and White, Black-throated Green, Parula, and literally hundreds of Yellow-rumps. I also saw both Rose-breasted and Blue Grosbeaks, and Orchard and Baltimore Orioles there this week.
Go outside and listen for interesting or buzzy bird songs, then look at them. It is probably a warbler.
We have a house full this weekend at the shore with the Bird Nerds plus Patty for World Series scouting. Hopefully, the next post will have photos.
