Warblers in S Vermont in Help Me Identify a North American Bird Posted September 3, 2018 Looking back at my pics and thinking about the timeline, I believe the Empid you identified as possibly yellow-bellied was a Least flycatcher. I heard the distinct calls of 2 of these birds and was thinking that was what I was seeing when I took the pic. I just didn't remember that when going through my pics and posting. Here is another shot of the same bird right before it flew. Thanks again psweet.
