 Razorbill - Wikipedia, the free encyclopedia
The Razorbill, Alca torda, is a large alcid, 38-43 cm in length, with a 60-69 cm wingspan.
While the Razorbill is the only living species, the genus Alca had a much higher diversity in the Pliocene.
As far as is known, the genus seems to have evolved in the western North Atlantic or the present-day Caribbean, which its ancestors would have reached through the still-open Isthmus of Panama during the Miocene (Bédard, 1985).
