A small seabird found along the coasts of the northern Atlantic and Arctic oceans. It is known for its striking black plumage during the summer and its incredible ability to swim and dive for food. These birds live in cold coastal regions, from Canada and Greenland to northern Europe and Russia. They are well-adapted to their environments and are fascinating creatures to observe.

One of the most distinct features of the black guillemot is its summer plumage. During this time, the bird’s feathers are jet black, with a bold white patch on each wing. This white wing patch stands out sharply against the dark body, making the black guillemot easy to recognize. Its legs and feet are bright red, adding another pop of color to its appearance. In the winter, however, the bird’s feathers turn mostly white with some dark markings, helping it blend in with the snowy and icy surroundings.

Black guillemots are excellent swimmers and divers, which helps them catch their food in the cold waters where they live. They hunt mainly for small fish, like cod and herring, as well as crustaceans and other small sea creatures. These birds use their wings to propel themselves underwater, moving with speed and precision to catch their prey. They can dive deep and stay underwater for longer periods compared to many other birds, making them great hunters in the ocean.

Unlike many seabirds that nest in large colonies on cliffs, black guillemots prefer to nest in small, hidden spaces. They often choose rocky crevices, cracks in cliffs, or even man-made structures like piers to make their nests. This helps protect their eggs and chicks from predators.
