Spotted
This bird is a hybrid of a Redhead (Aythya americana) and either a Greater or Lesser Scaup. Identifying this hybrid can be challenging due to its intermediate features, combining aspects like the Redhead's rounded head and the scaup's distinct bill shape and potential iridescent head sheen.
Where to spot
Look for this hybrid on large freshwater marshes, lakes, and coastal estuaries, especially in North America where these species' ranges extensively overlap.
How to spot
Focus on bill color (often blue-grey with a black tip), head shape (rounded vs. peaked), and overall body plumage. Note any features that don't quite fit a pure Redhead or pure scaup, such as variations in head sheen or eye color.
When to spot
Best observed during fall and spring migration or in wintering grounds when larger groups of diving ducks are present on open water.

Inter-species hybrids often show traits that are intermediate between the two parent species, making them fascinating subjects for identification by experienced birdwatchers.
