  Scott Islands - Common Murre   (Site not responding. Last check: 2007-11-05)
The common murre is a sleek, duck-shaped bird that resembles a penguin: fl down the back and white in the breast and belly.
Common murres pursue a varied diet, feeding on fish, squid, shrimp-like crustaceans called krill, and even marine worms.
During the winter, common murres are distributed along both inner and outer coastal areas and prefer the protected marine areas off straits, inlets, bays and channels.

 ::Seabirds:: (Common Murre)
The common murre is one of the success stories of the sea – about 10 million breed in the northern parts of the Pacific and Atlantic Oceans, and millions more are young birds that are gaining the experience they’ll need to attempt nesting the first time.
Common murres can fly 200 kilometers from the nest to find food for their chicks, and may dive as deep as 100 meters for food, but 70 kilometers and 50 meters are probably more typical maximums.
Murres feed their chicks three to five fish a day, and adults eat mostly fish too, but they may also consume zooplankton and squid.

The common murre is one of twenty different species in the Family Alcidae that breed in North America.
The common murre predominantly produces two types of calls or sounds; the first call is a low guttural croaking sound followed by a high-pitched bleat, while the other sound they make is a "murmuring" sound for which they derived the name murre.
This is primarily because the cliffs and ledges act as a platform for the murre to lay its egg.

 Common Murre--BIOLOGICAL AND ECOTOXICOLOGICAL CHARACTERISTICS OF TERRESTRIAL VERTEBRATE SPECIES RESIDING IN ESTUARIES

 EVOS-Oil Spill Facts-Status of Common Murres   (Site not responding. Last check: 2007-11-05)
Interpretation of the effects of the spill, however, is complicated by incomplete prespill data and by indications that populations at some colonies were in decline before the oil spill.
Common murres will have recovered when populations at index colonies have returned to prespill levels and when reproductive success (productivity is sustained within normal bounds.
During the period 1993-1997, the murres nested progressively earlier by 2-5 days each year, suggesting that the age and experience of nesting birds were increasing, as might be expected after a mass mortality event.
