Spear-like plunge diver

Gannets fold wings and strike the sea from 10–30 m, using air sacs under the skin to cushion impact. Adults are white with black wingtips and a golden head wash; juveniles are dark brown.

Pursuit of pelagic fish

Mackerel, herring, sand eels, and other schooling fish are taken underwater after the plunge. Birds may form large feeding flocks over productive upwellings.

Atlantic cliff cities

Breeding colonies crowd sea cliffs from Maritime Canada and Scotland to Norway — Bass Rock and Bonaventure Island are famous. Non-breeders roam the open North Atlantic year-round.

Fisheries and plastic risk

Least Concern with millions of pairs globally. Bycatch in nets, oil pollution, and ingested plastic still kill birds, but populations remain large and widespread.
