These pictures were taken at various times in various places around the United States. All 6 birds pictured (maybe 6 different species, maybe not) do occur in Utah annually. This is just for fun so feel free to take a stab and maybe talk about why you assigned an ID to a certain bird. Empidonax Flycatchers are a tough group of birds and we could all use a little discussion to improve our ID skills!
The hardest part about a visual headshot quiz is that there is no habitat, no song, and no primary projection to help in the ID--all we have is apparent head shape, bill, size, and color, eye-ring, etc.
I will post a full recap on the birds, where they were photographed, etc in a couple days. If you can't wait, all the photos are posted on my website--but please don't post answers if you go there and look first!
