Great Black-backed Gull: Gull as Predator

Written by Bob Sundstrom

This is BirdNote.

A massive bird soars along the New England coastline, above nesting islands and cliffs inhabited by puffins and other seabirds. This bird’s broad, black wings measure more than five feet across, in bold contrast with its white head and tail. Its beak is long and thick.

A Bald Eagle might come to mind. But this is no eagle. It’s a Great Black-backed Gull, the world’s largest gull.

Great Black-backed Gulls can be found on both sides of the North Atlantic. And their diet — like that of other large gulls — includes fish, squid and winter visits to landfills.

But it’s their reputation as serious predators of other birds that really sets this huge gull apart. During the nesting season, Great Black-backed Gulls prey on eggs and nestlings of other seabirds. They’ll also hunt adult seabirds, like puffins and grebes, and songbirds as big as a grackle.

Just over a century ago, these birds were nearly wiped out by plume hunters. The gull that soars like an eagle and snacks on other birds had itself all but disappeared into ladies’ hats. But today, thanks to people speaking out, these gulls are thriving.
