Arkie,

You are the person actually seeing the birds, and are the best person to judge. You also get species that I don't see here in the East and that are not in my Peterson's or Audubon field guides. However, all the Peedees, Flycatchers and Pheobes that I have seen or seen in my field guides have dark, beaks, shaped much differently from what I see in your photo. I also realize there is a lot of light reflecting off the beak in the photo, it perhaps is not as light as it appears in the photograph, and the angle may make the beak appear shorter, broader and more wedge-shaped than it is in actuality. (One of the reasons I prefer the Peterson guides, whether it be birds or plants, to the Audubon guides or other guides that use photographs rather than high quality drawings.)

Based solely on the photo, though, I still vote for a slate-colored/dark-eyed junco.

Terrific photos, btw. You and ragdall both take wonderful pictures.
