What feature distinguishes the winter plumage of the Sabine’s Gull when compared to its breeding plumage?
Answer
Lacking the distinct dark hood of the breeding bird
The visual appearance of the Sabine’s Gull undergoes a transformation between the breeding season and the wintering period. During the summer months in the Arctic, the bird is characterized by a distinct black cap or hood covering its head. When the population arrives at its tropical and subtropical wintering grounds far from land, this distinct head marking is lost. The winter plumage is characterized by the absence of this specific dark hood, requiring observers seeking this alternative look to travel out on pelagic boat trips in warmer waters.
