As promised, here are a few more details on the Mystery Bird Quiz #8 bird. This image was taken in early August in Pawnee Grasslands in Colorado.
So I believe we can rule out male northern cardinal as a potential answer. It's also probably not an eastern wood warbler. Or an anhinga.
Here is shot of the habitat where I took the image. What a day that was. Out in the great wide open, nothing but land, sky, clouds, birds, a few pronghorn antelope, some distant cattle, and a windmill here and there. What a lark!
Staring at this scene, I found myself singing that Jackson Browne song:
Throw me over the edge and let my spirit glide.
Maybe it's being an Iowa-born native that allows me to feel so relaxed and happy in the big-sky places...
Good luck with your guessing, birdheads!
