Razorbill (Alca torda) adult standing on rock of coastal cliff
he species breeds on islands, rocky shores and cliffs on northern Atlantic coasts, in eastern North America as far south as Maine (U.S.A.), and in western Europe from north-west Russia to north-west France. North American birds migrate offshore and south, ranging from the Grand Banks of Newfoundland (Canada) to New England and New York
The razorbill is a colonial seabird that only comes to land in order to breed. This agile bird chooses one partner for life; females lay one egg per year. Razorbills nest along coastal cliffs in enclosed or slightly exposed crevices. The parents spend equal amounts of time incubating. Once the chick has hatched, the parents take turns foraging for their young and sometimes fly long distances before finding prey.
