Murres are seabirds belonging to the family Alcidae, which also includes puffins and guillemots. They are known for their striking black and white plumage and are often found in large colonies along rocky coastlines. Murres are excellent divers, using their wings to propel themselves underwater while hunting for fish and other marine prey. These birds typically nest on steep cliffs, laying a single egg that both parents take turns incubating. Murres are social creatures, often seen swimming and flying in groups. They are primarily found in the northern hemisphere, particularly in the North Atlantic and North Pacific oceans.
