Identifying female ducks


Some female ducks are distinctive, most are not. Many birders, even advanced birders, seem to find identifying female ducks a chore (and it can be difficult), but most female ducks give enough clues to allow a positive ID without too much trouble, if you commit a few silhouettes and plumage patterns to memory.



Distinctive female ducks include:

Northern Shoveler, Wood Duck, Common Merganser, and Bufflehead


Northern Shoveler should be easily identified by its very large, flattened bill. Wood Duck females have a distinctive eye ring and white stripe behind the eye. Look also for Wood Duck’s distinctive head shape. Female Common Merganser has a bright red, serrated-edged bill and a shaggy reddish-brown crest. Female Bufflehead can be identified by its small size but proportionately large, dark brown head with white cheek patch.
