I did not get a chance to check the Noble Research Center until 4:00 pm today but when I did there was a sad surprise at the northeastern alcove. It looks for all the world like these two were traveling together, although I certainly cannot establish that to be the case:
AHY-F Dark-eyed Junco, fat = 0.
AHY-U Fox Sparrow, fat = 1.
This is just the second Fox Sparrow I’ve found on this project.
