I checked out the bird recently reported by Wendy VanDeWalle at the wetlands at the intersection of Wagner Rd. and Dunkerton Rd. just north of Waterloo. It looks to me like a typical adult male Cinnamon Teal in breeding plumage. In the bright sunlight, there is a greenish iridescence in the head when viewed from some angles, but the head looks completely cinnamon in color from other angles. I tried to do some internet research on this point. Certainly some of the pictures labeled as Cinnamon teal show this green iridescence in the head, as does my copy of the Sibley guide, 2nd ed., so I presume that this characteristic is consistent with Cinnamon Teal. It does not show any of the illustrated characteristics of a cinnamon x blue-winged teal hybrid, which is the only hybrid with Cinnamon Teal that I have been able to find mentioned in any of my reference sources. I would guess that any other cinnamon teal hybrid would be quite rare.
