Here are a couple of pictures of an Eastern Wood-Pewee. I have just a tinge of doubt that this not a Wood-Pewee, but is instead one of the Empidonax flycatchers. But only a tinge.
I decided that since I can see no eye-ring in these pictures then this is not an Empidonax. There are other field marks that you can use besides the eye-ring, but I am afraid that if I listed them...then you would think that I actually applied that information intelligently. No, I only used the eye-ring.
