Black-legged Kittiwake

Black-legged kittiwakes are ocean-going gulls of northern Atlantic, Pacific and Arctic waters. Adults have white bodies, gray backs, black wingtips, yellow bills and dark legs. They spend much of the nonbreeding period at sea, feeding over open water, but gather in noisy colonies during the breeding season. Nesting typically occurs on narrow ledges along steep coastal cliffs, where terrestrial predators have limited access. (Animal Diversity Web)

Kittiwake pairs build compact nests from mud, vegetation and other available material. Both adults incubate their eggs and feed the nestlings, which remain relatively secure on the cliff ledges until fledging. These gulls obtain food mainly from the sea, taking small schooling fish, crustaceans and other marine invertebrates from or near the surface. They may forage alone but frequently concentrate where prey becomes locally abundant. (Animal Diversity Web)
