Mallard/Mexican Duck Complex
-
Not yet spotted on Fladder
Spotted
This designation describes ducks showing a blend of traits from Mallards and Mexican Ducks, a result of extensive hybridization that has led to a complex genetic landscape in their shared range. Pure individuals can be hard to find.
Where to spot
Throughout the southwestern US and Mexico, particularly in areas with both native Mexican Ducks and introduced or resident Mallards.
How to spot
Identifying these birds requires careful observation of plumage, bill color, and speculum patterns, as they can exhibit a wide range of intermediate characteristics. It often involves noting features that don't quite fit either parent's typical description.
When to spot
Year-round, given the resident nature of the parent species.

The continuous spectrum of appearances within this complex makes definitive identification of 'pure' Mexican Ducks challenging in some regions, highlighting the impact of human-induced habitat changes and introductions.
