Fratercula

 

a genus of birds of the family Alcidae. The body is 30–35 cm long with a weight of 450–500 g. The tall, brightly colored bill is highly compressed. The back is black, and the lower part of the body white; the feet are orange-red. Fratercula walk, fly, swim, and dive well. Their diet consists of small fish and marine invertebrates. The birds nest in groups or colonies along steep seacoasts; a single egg is deposited in a deep burrow dug in soft ground, under rocks, or in cliff crevices. The nestling is covered with a long, soft, dense down; it leaves the nest completely feathered. F. arctica inhabits the North Atlantic eastward to Novaia Zemlia; F. corniculata inhabits the northern Pacific coasts.

Campbell (1969) found a few Storm-Petrel burrows on Cox Island in 1966, but RW Nelson and KR Summers reported that the Tufted Puffin (Fratercula cirrhata) was the only burrow-nesting species remaining on Cox Island in 1971, and a field party from the British Columbia Provincial Museum (now Royal British Columbia Museum) confirmed the absence of Cassin's Auklet on Langara and Cox islands in 1977 (Rodway and others, in press).

Species that nest in burrows (Atlantic puffin Fratercula arctica) or on the ground (northern fulmar Fulmarus glacialis, great black-backed Larus marinus and herring gulls Larus argentatus) did not fledge any offspring in 2009, and common murres (Uria aalge) at this colony, the largest for this species in North America, experienced an estimated 4.9% (-19712.4 breeding pairs) reduction in the number of nesting birds.

Few Arctic marine birds nest in burrows (except possibly some Atlantic puffins Fratercula arctica at some locations; Robards et al., 2000), and rainfall is typically insufficient to flood nests, although heavy snowmelt can create flooded conditions for ground-nesting species.
Earliest records for each species were: Ancient Murrelet (Synthliboramphus antiquus) at St Lazaria Island, SEAK, in 1866; Cassin's Auklet (Ptychoramphus aleuticus) at Forrester Island, SEAK, in 1897; Rhinoceros Auklet (Cerorhinca monocerata) at Pine Island, BC, in 1860; and Tufted Puffin (Fratercula cirrhata) at Mandarte Island, BC, in 1858.
