Dark-bellied Brent Goose x Black Brant Hybrid

Not yet spotted on Fladder
Spotted
This hybrid combines genetic traits from the Dark-bellied Brent Goose (Branta bernicla bernicla) and the Black Brant (Branta bernicla nigricans), resulting in plumage that mixes characteristics of both parent subspecies.
Where to spot
Likely encountered in wintering areas where both parental subspecies naturally occur, particularly along coastal regions of Europe and North America where Dark-bellied Brent Geese and Black Brants may overlap or stray.
How to spot
Look for a blend of features: a belly that is darker than a typical Dark-bellied Brent but not as uniformly black as a Black Brant. The white neck patches might also show an intermediate extent or shape. Note any unusual vocalizations or behaviors.
When to spot
Similar to the parent species, these hybrids are most often observed during the non-breeding season from autumn through spring (October-April) in coastal habitats.

Hybrids between Brent Goose subspecies are a testament to the ongoing genetic interactions within this species complex, often arising in areas where their ranges overlap.
