Brunnich's murre:

see murremurre
, common name for a group of diving birds of the same family as the auk and the puffin (family Alcidae) and including the guillemots. There are three species of murres, all about 18 in. (45 cm) long, brownish black above and white below.

In 1954-98, a total of 11 145 Brunnich's guillemots were ringed in colonies in Svalbard (Table 1).
The distribution of winter (October-March) recoveries (immatures and adults) of Brunnich's guillemots ringed in Svalbard and in other northern Atlantic colonies (Fig.
Since the reporting of ringed birds is dependent on human presence, Brunnich's guillemots staying offshore or in coastal areas outside the hunting zones have a minimal possibility of being found and reported.
An unknown proportion of the Brunnich's guillemots ringed in Svalbard migrates southwest in the autumn and spends the winter close to Iceland, Greenland, and Newfoundland.
Brunnich's guillemots occur offshore and in coastal waters in the Barents Sea outside the breeding season (Barrett, 1979; Anker-Nilssen, 1988; Bakken, 1990; Erikstad, 1990; Isaksen, 1995; Mehlum and Isaksen, 1995; Hunt et al., 1996).
In conclusion, the tendency for immature Brunnich's guillemots ringed in Svalbard to disperse earlier and farther in winter than the older birds is similar to that observed for birds ringed in Canada (Gaston, 1980; Donaldson et al., 1997).
We are grateful to the ringing centres in the United States, Canada, Iceland, Greenland, Russia (Kandalaksha State Nature Reserve), and Norway for access to the data on recovery of Brunnich's guillemots in the North Atlantic.
5) strongly suggests that ice distribution is important in determining the vulnerability to hunting of juvenile (and second-year) Coats Island Brunnich's guillemots. In years when the ice front remains north of 49[degrees]N, the population has a wide choice of feeding areas off the Newfoundland coast.
If this is a general pattern, the changes that we describe here may lead to a shift in hunting pressure towards Brunnich's guillemots from more northerly colonies.
Changes in the number of birds shot by hunters and, to a lesser extent, changes in the size of the total population, probably contributed to the steep decline in recovery rates for Coats Island Brunnich's guillemots in Newfoundland over the past two decades.
