kittiwake

Imagine a rugged coastline where the air is filled with salt spray, crashing waves, and the cries of birds. Among the swirling flocks, you might spot a kittiwake, a graceful seabird that belongs to the gull family. Known for its neat shape and black wingtips that look as if they were dipped in ink, this bird is truly at home on sea cliffs. Unlike the gulls you might find stealing fries at a boardwalk, kittiwakes spend much of their lives out over the ocean and return to steep rocky coasts to breed.

The name "kittiwake" is an imitation of the bird's own shrill, rhythmic call: "kitti-wake, kitti-wake!" These birds are social and are often found in large, noisy colonies, where they build nests of seaweed, grass, and mud. If you are hiking along a northern cliff, listen for that sharp call; it is one of the signature sounds of the open sea.

A kittiwake is a small ocean-going gull in the genus Rissa. The word is most often used for the Black-legged Kittiwake (Rissa tridactyla), though it can also refer to the Red-legged Kittiwake (Rissa brevirostris). These birds belong to the gull family, Laridae, but they live a little differently from the gulls many people know from beaches, harbors, and city streets. Kittiwakes spend much of their lives far out over the sea and come back to land mainly to breed, especially on steep coastal cliffs in cold northern regions.

You can often identify a kittiwake by its clean white head and underparts, pale grey back, and black-tipped wings. In the common black-legged species, the legs are dark, and the bill is yellow. The name is onomatopoeic, taken from the bird's own call. Unlike many other gulls that are quick to scavenge around people, kittiwakes depend mostly on the sea, feeding on small fish and sea life near the surface.

These birds are well known for nesting in crowded colonies on narrow cliff ledges, where they build cup-shaped nests from mud and plant material. This cliffside life helps protect their eggs and chicks from many land predators. Today, kittiwakes are also known in discussions of climate and marine ecosystems, because their numbers can be affected by warming seas and changes in the fish they rely on. To watch a colony of them wheeling above the rocks is to see a vivid part of northern coastal life: noisy, restless, and closely tied to the health of the ocean.
