Blue-headed Vireo it is

The solitary-type vireo that I found at 'Lamar Wood's in Lamar, CO yesterday appears to be a Blue-headed Vireo, a rare vagrant in Colorado. Since this is the first time I had seen this species, I wasn't very sure that it was a Blue-headed and not a Cassin's Vireo which is similar. Since posting 'raw' photos (cropped only with no tweaks) I have received emails from several highly skilled birders who said they believed this to be a Blue-headed. More photos, tweaked a little, in next post. SeEtta
