NAME: ‘Murre’ might have an onomatopoeic origin, as it resembles the bird’s call. Latin genus name ‘Uria’ refers to ‘a dark water bird’. Latin species name ‘lomvia’ refers to some kind of small diving bird. This bird is also called Brunnich’s Guillemot.
HABITAT: Rocky cliffs in summer, open seas outside breeding season.
DIET: Dives from water surface for fish, squid, crustaceans.
NESTING: Breeds in large dense colonies on rocky cliffs facing the water. One single light blue-beige egg is laid on bare rock, and incubated by both parents. Chick fed by both parents.
DISTRIBUTION: Breeds in the Arctic around the globe. Winters in open ice-free seas in North Atlantic, Hudson’s Bay and North Pacific. There are several cases of vagrants ending up as far south as California or Florida (see note below on bird vagrancy).

ON PEI: Does not breed on Prince Edward Island, sightings rare or uncommon in the fall.
CONSERVATION: Population widespread and numbering around 15 million, not at risk.
NOTES: This murre is a North Atlantic seabird of the alcidae family. It can easily swim underwater as if flying, but is clumsy when walking on land. It can dive at depths reaching 150 meters (490 feet). The bird looks like a penguin but is not related to it.
Vagrancy: In biology this means an animal going way outside its normal range. For birds, this can happen when there are storms and they get blown off course. On other times, the bird simply wanders in a different direction than usual. Here’s an article about vagrancy in birds.
