We think the above flycatcher is a Willow, and the one below is a Least Flycatcher.
Congrats to all those who ID'd them correctly. These guys are really tough! (Thanks, Roy!)
As Roy Woodford points out: "You don't have to go far from the front parking lot at DeKorte to find an Oriole or three (or more).
"These guys are everywhere this year (the females are around but they seem to be a bit camera shy). Last year, I had a hard time finding one of each." (Thanks, Roy! Orchard Oriole pix follow.)
Note: Baltimore Oriole above is banded!
