Ruddy Duck x White-headed Duck Hybrid

Spotted
This entry refers to a hybrid individual resulting from the interbreeding of the invasive Ruddy Duck (Oxyura jamaicensis) and the endangered White-headed Duck (Oxyura leucocephala). This hybridization poses a significant conservation threat to the pure White-headed Duck populations.
Where to spot
Primarily in Western Europe, particularly in countries like Spain, France, and the UK, where Ruddy Duck populations have become established and come into contact with the range of the White-headed Duck. They inhabit freshwater wetlands, lakes, and marshes.
How to spot
Look for ducks exhibiting a mix of features from both parent species. Key features to note include bill color (blue), face pattern (extent of white and black), and overall plumage (rufous body). Identification can be complex due to the variability in hybrid characteristics. Be aware that these birds are often a target for eradication efforts in Europe.
When to spot
Year-round in areas where both parent species coexist. Observation can be challenging as hybrids may have varied appearances.

The spread of Ruddy Ducks from North America into Europe and their subsequent hybridization with native White-headed Ducks has led to extensive control programs to protect the latter species.
