Ancient Murrelet

 

(Synthliboramphus antiquus), a bird of the family Alcidae of the order Charadriiformes. The ancient murrelet is about 25 cm long and weighs about 200 g. The back is gray, the head is black with a white stripe, and the underside is white. The bird is common along the coasts and on the islands of the north Pacific Ocean. In the USSR it is distributed from Kamchatka and the Komandorskie Islands to the northern part of Primor’e Krai and, possibly, Sakhalin. The ancient murrelet migrates south in winter to Japan and California. Nesting occurs on coastal cliffs; two eggs are laid, customarily in crevices or under stones. The diet consists of small marine invertebrates. A related species, S. wumizusume, nests in Japan and is occasionally encountered along the coasts of the USSR.

Non-breeders may visit colonies later in the season and for several years prior to breeding, as reported for Ancient Murrelet (Synthliboramphus antiquus) (Gaston 1992) and Common Murre (Uria aalge), in which subadults tend to arrive earlier at the colony as they become older, and some subadults visit non-natal colonies prior to returning to their natal colony to breed (Halley and Harris 1993; Halley and others 1995).
The Ancient Murrelet (Synthliboramphus antiquus), the 5th species, still nests on Langara Island, but in greatly reduced numbers (Rodway and others 1994; Bertram 1995; Regehr and others 2007; Major and Jones 2011).
