Not yet spotted on Fladder
Spotted
This hybrid results from interbreeding between the Pale-bellied Brent Goose (Branta bernicla hrota) and the Black Brant (Branta bernicla nigricans), presenting a unique blend of their contrasting plumages.
Where to spot
These hybrids are rare and most likely to be seen in wintering areas where strays of one subspecies might encounter the other, such as parts of North America or potentially Europe.
How to spot
Identifying this hybrid requires keen attention to detail. Look for a belly that is darker than a pure Pale-bellied Brent but significantly paler than a pure Black Brant. The white neck patch may also appear intermediate in size or shape.
When to spot
Observation opportunities are best during the non-breeding season (October-April) when Brent Geese gather in their coastal wintering grounds.

Hybridization, even between geographically separated subspecies, can occur when individuals stray from their typical migratory routes, leading to fascinating and sometimes perplexing identification challenges.
