That new hybrid duck is thoroughly cool. I've never seen one quite like that before. I'm going to propose that it is a Mallard x Green-winged Teal. Mallard genes are clearly dominant, but the bill is smaller, and not as elegant as in the 'Brewer's.' One thing I note on male 'Brewer's' is that they all seem to have broad, black undertail coverts, whereas this bird has black seemingly confined to the central undertail coverts, as in Green-winged (but not American Wigeon). Further, the retained juvenile feathers on the lower scapulars and upper flanks very much remind me of those still found on many young male Green-winged that have yet to complete preformative molt. So, if a MALL x GWTE, this bird appears to have inherited the molt-timing of the latter species.
thanks for sharing, Jim
