In honor of the Eurasian Green-winged Teal we saw on one of our recent guided walks, we offer the following teaser, courtesy of Claus Holzapfel — a perfect shot for those who are totally immersed in duck IDs.  

Can you ID these three ducks? 

Thanks, Claus! A previous G-W Teal post (with a right-side-up view) is here.
