Spotted
This hybrid is the offspring of a Tufted Duck (Aythya fuligula) and either a Greater or Lesser Scaup, exhibiting a blend of traits from both parent species. Identifying these hybrids requires careful observation of subtle plumage and structural details.
Where to spot
Found on freshwater lakes, reservoirs, and coastal areas where the ranges of Tufted Ducks (Eurasia) and scaups (Holarctic) overlap, or where vagrancy occurs, allowing for interbreeding.
How to spot
Scrutinize the head for signs of a crest (Tufted Duck) combined with the general size, bill shape, and overall plumage pattern of a scaup. Note eye color, bill features, and the extent of white on the flanks.
When to spot
Year-round, but more easily distinguished when flocks of diving ducks are present, typically during migration or winter when they gather on open water.

Hybrids can pose significant challenges for identification, as they often exhibit a mosaic of features that can be misleading or confusing, making each sighting a unique puzzle for birdwatchers.
