[cobirds] Re: Hybrid duck

Hi all --

This duck has been on the South Platte for at least four winters. It has been ID'ed as a Northern Shoveler X Gadwall hybrid. See the comments under a photo of it posted on January 29 to the Colorado Field Ornithologists Facebook group for more discussion and links to helpful websites.

Hope this helps,

I'm just sending this email to retitle it so that when people respond to it, it won't have part of my name in the response. This duck was discovered by other great birders, I had nothing to do with it…
Thanks, Deb Carstensen, Littleton

Hi Leon,

Thanks for your input.  Certainly the hybrid duck photographed by Rob Raker has characteristics that could be due to a wigeon x pintail combination.  I looked through dozens of photos of hybrid ducks and couldn't find any that looked like the specimen Rob saw on the Platte.  I still thought that the duck might be a shoveler x gadwall combination.  When I searched on that hybrid, the photo I found did look more like Rob's duck than the other photos I found.

Perhaps someone with extensive experience with hybrid ducks would care to join the discussion.

Here's another guess:  American wigeon x pintail.  Note the scapulars, tertials and under-tail coverts.  What about the absent "pin" tail, and the white auriculars, you say?  Well, umm…
