Gadwall x Northern Shoveler

This highly distinctive hybrid is usually quite a surprise when people first come across it - who would have thought that a hybrid between Gadwall and Shoveler would have such an obvious pale cheek!  Actually several Gadwall hybrids have pale buffy cheeks, though not always as obvious as this.  The bronzy-coloured cap is also shared by some other Gadwall hybrids, e.g. Gadwall x Mallard.

Cathy photographed this bird when it returned for at least its third winter.  That's not white plumage on its tertials and rear scapulars - it's frost.  Brrrr!

This bird retuned to the same location in the next two successive springs.  Here it is in 2017.
