RAZOR BILL / ALCA TORDA

The Razorbill (Alca torda) 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.
The Razorbill is primarily black with a white underside. The male and female are identical in plumage; however, males are generally larger than females.
The Razorbill chooses one partner for life, and nests along coastal waters of the continental shelf. It nests in open or hidden crevices among cliffs and boulders. It is a colonial breeder and only comes to land to breed. The annual survival rate of the Razorbill is 90%. Though the Razorbill’s average lifespan is roughly 13 years.
