Cameron and I birded around Philadelphia today, starting at Tinicum where we found lots of ducks and good numbers of Rusty Blackbirds as well a young male American Redstart. Bonus points go to whoever can find the redstart in the images below. I tried my best but it was so active I couldn’t get it in the viewfinder.
Afterwords we ran up to the sewage treatment plant just below the Betsy Ross Bridge and found over 100 N. Rough-winged Swallows but no Cave Swallows.
