Razorbill

Alca torda

  • rare
  • 55 km/h
  • Least Concern

Closest living relative of the extinct Great Auk. Carries that legacy in a heavy black-and-white bill.

Population
838,000-1,660,000 mature individuals, increasing
Habitat
Rocky cliffs, offshore islands, and sea stacks on North Atlantic coasts for breeding (cliff ledges and under boulders in boreal/low-Arctic waters with sea-surface temperatures below ~15C); pelagic/open ocean, mostly within 10 km of shore, the rest of the year
Fun fact
Razorbills typically live around 13 years, but a bird ringed in the UK in 1967 was recovered still alive at least 41 years later, the longevity record for the species.
Range
North Atlantic: breeds from northeastern North America (Maine to Arctic Canada) and Greenland across Iceland (holding ~60-70% of the world population), the UK/Ireland, and Scandinavia to northwestern Russia and northwestern France; winters at sea south to the western Mediterranean, North Africa, and the mid-Atlantic US coast
Diet
Mid-water schooling fish (capelin, sandeels, herring, sprat, juvenile cod) caught by pursuit-diving (capable of depths to ~120m though typically forages nearer the surface), plus krill/other crustaceans and polychaete worms
Size
0.38 m
Wingspan
0.655 m
Lifespan
41 years
