Behaviour The Common Guillemot is a pursuit-diving marine
bird which forages
primarily during daylight. One parent remains
at the colony
with the chick whilst the other is on a foraging
Birds departing colonies usually splash-down to form large rafts
close to the colony before departing to foraging areas. External
radio tagging has been shown to adversely effect breeding1,2,
whereas birds fitted with internal transmitters behaved as normal2.
During the breeding season
pelagic fish species
are the most important prey
, though benthic
also be important.In Labrador, Canada, Shannies (Sticheaidae) were
the main source of food, comprising 84% of the diet in 1996 and 52.9%
in 19973. Capelin (Mallotus villosus) were
also important, forming 44.7% of the diet in 19973.
In the UK, the main prey taxa are sandeel (Ammodytes spp.
and clupeids. Small gadoids are also important at some colonies.
Foraging range This species dives to maximum depths of 170-230m.
During the breeding season, surveys recorded the highest densities
of birds in the 51 - 100 m
depth zone, although birds were still
abundant in water less than 50 m and 101 - 200 m deep. Very few were
seen in deeper areas4. The foraging range of this
species appears variable across seasons
and years. At the Isle of
May, Scotland, during 1986 around 70% of foraging trips were over
from the colony, whereas in the following year the birds tended
to make shorter trips4. Foraging trips in eastern
Canada are within 100 km5,6, and in Pribilof Islands,
Alaska, foraging occurred mostly within 60 km. In Witless Bay
foraging aggregations formed over large Capelin schools
km of breeding sites. Along the Newfoundland coastline, aggregations
occurred within 15 km of the colonies, and at an offshore ridge
80 km southeast of the colonies. Despite these large foraging radii,
waters close to the colony were the most frequent destination of
feeding birds. This was particularly true during chick rearing
only one third of feeding trips could have exceeded 10 km from the
colony5. In Pribilof Islands, Alaska, birds
showed a consistent preference for shallower waters7.
High densities of foraging birds have also been observed foraging
over a submarine ridge8. In Kachemak Bay,
Alaska, it appears that birds tend to feed
over rocky substrates
in water depths of about 18 to 55 m9. They have
also been observed to forage in riptides4, and
in areas of sandy sediment suitable for sandeels10,11.
Near Flamborough Head
, UK, the Farallones, California, and Pribilof
Islands, Alaska, birds forage at fronts between thermally distinct
bodies of water. In the UK example, this occurs at a seasonally-occuring
front between thermally-mixed and thermally-stratified water, whereas
in the Farallones, the front was between cold and salty upwellings
