Ferruginous Duck x Red Shoveler Aythya nyroca x Anas platalea

This one is a captive bird; the Anas parent is uncertain but if we assume the parent was still in the same collection when it was first seen (which isn't the case for at least one hybrid seen there) then the most likely choice (in view of the bill shape) is Red Shoveler.
