The Razorbill/Crosán (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. In 1918, the Razorbill was protected in the United States by the Migratory Bird Treaty Act. Presently, the major threat for the population is the destruction of breeding sites.

The Razorbill has white underparts and a black head, neck, back and feet during breeding season. A thin white line also extends from the eyes to the end of the bill. Its head is darker than that of a Common Guillemot. During the nonbreeding season, the throat and face behind the eye become white, and the white line on the face becomes less prominent. The thick black bill has a blunt end. The tail feathers are slightly longer in the center in comparison to other alcids. This makes the Razorbill have a distinctly long tail which is not common for an auk. The Razorbill chooses one partner for life, and nests along coastal waters of the continental shelf. (wikipedia)
