On Monday I asked readers to identify a bird and a mammal I photographed recently at Audubon's Homestead in Mill Grove, Pa., outside of Philadelphia.

For the above photo, Louise Riccobene said... Yellow-rumped Warbler! 

Looks good to me. (And an immature one at that.)

For this photo, I asked: Fox or Coyote?

Chris Alber said it was a mangy Red Fox, and Peter Burger concurred. I do, too.

(Thanks, all!)
