Tundra Swan x Bewick's Swan Hybrid

Spotted
As Tundra Swans (North American) and Bewick's Swans (Eurasian) are often considered subspecies of the same species, hybrids between them are exceedingly difficult to distinguish and usually exhibit subtle intermediate bill patterns.
Where to spot
Extremely rare. Potentially where their ranges might marginally overlap in Alaska or eastern Siberia, or in captive collections. Documented wild occurrences are very limited.
How to spot
Look for a swan with a bill pattern that doesn't clearly fit either a typical Tundra Swan (yellow spot, mostly black) or a typical Bewick's Swan (more yellow, variable). It might have a larger or smaller yellow patch than typical for a Tundra, or less yellow than typical for a Bewick's.
When to spot
Opportunistic, likely during migration periods in areas of potential overlap, or year-round in captivity.

The identification of such a hybrid primarily relies on minute variations in bill patterns (the amount of yellow and black) that fall outside the typical range for either parent subspecies, often requiring expert evaluation.
