Sula bassanus
The gannet, with a 1.8 m wingspan, is the largest seabird breeding in North American waters. It feeds primarily on surface-dwelling fish such as herring and mackerel which are taken by diving from heights up to about 43 m and plummeting into the water at great speed and considerable force. The bird’s skull is especially strong, and a system of air sacs also helps to absorb the shock of these plunges.
Gannets nest on steep cliffs of Canada’s east coast. The nests are large, between 30 cm to 60 cm high, are made from a mixture of vegetation, seaweed, feathers, and earth, and may be cemented with guano.
The North American gannets winter at sea, from Virginia to southern Florida, and return to their breeding grounds in early April.
