How is the striking adult breeding plumage of the Xeme instantly recognizable?
Answer
A striking black head contrasted sharply against the pale gray and white body.
The visual distinction of the adult Sabine’s Gull during the breeding season is defined by a high-contrast appearance. The most notable feature is the bird’s head, which is solid black, providing a sharp visual separation from the rest of its body plumage, which remains pale gray and white. This distinct visual characteristic is hypothesized to play a specific, perhaps signaling, role in courtship rituals or territorial defense displays that occur during the compressed timeframe of the Arctic summer.
