Black Brant

Branta bernicla nigricans

Regular vagrants from North America & East Siberia, 300 records for Britain & 50 for Ireland October-March.

Breeds in Siberia & North America.

This form is a very contrastingly black and white bird, with a uniformly dark sooty-brown back, similarly coloured underparts (with the dark colour extending furthest back of the three forms) and a prominent white flank patch; it also has larger white neck patches, forming a near-complete collar.
