They are highly mobile underwater using their wings to 'fly' through the water column, where they typically dive to depths of 30–60 m (100–195 ft). Depths of up to 180 m (590 ft) have been recorded. Common murres breed in colonies at high densities. Nesting pairs may be in bodily contact with their neighbours. They make no nest; their single egg is incubated between the adult's feet on a bare rock ledge on a cliff face. Eggs hatch after ~30 days' incubation. The chick is born downy and can regulate its body temperature after 10 days. Some 20 days after hatching, the chick leaves its nesting ledge and...
