755: 1083:, some of which are paired with displays, to communicate with others of its kind. One such display call pairing is the conspicuous hunch-whistle, where the tail is slightly raised, the wings held slightly out and the head thrown back 45-90° while whistling, before snapping back to horizontal. The function of this call is to advertise ownership of a territory. Another call, the trill, denotes ownership over larger distances. Trills can be performed singly or as duets between pairs; if performed as a duet then the call also functions to help reinforce pair bond. Trills are usually given from a resting position, except for the trill-waggle, which has the bird raising its tail, opening its wings and ruffling the feathers of its neck and head, followed by a waggling of its outstretched neck and head. This display is antagonistic in a context where pigeon guillemots are in a group and often is the precursor to an attack. Low whistles are made by unpaired males attempting to attract a mate, and are deeper than hunch-whistles and involve less movement of the head. Other calls made include seeps and cheeps made between mates and screams made in the presence of predators. 1115: 881:. The wings of the pigeon guillemot are shorter and rounder than other auks, reflecting greater adaptation towards diving than flying. It has difficulty taking off in calm conditions without a runway, but once in the air it is faster than the black guillemot, having been recorded at 77 km/h (48 mph), about 20 km/h (12 mph) faster than the black guillemot. In the water it is a strong swimmer on the surface using its feet. When diving, propulsion is provided both by the wings, which beat at a rate of 2.1/s, but unusually for auks also by the feet. Pigeon guillemots have been recorded travelling 75 m (246 ft) horizontally on dives. 835: 894: 1278:. This is due to multiple factors, including its large population, estimated at 470,000 individuals, its stable population, and its large range, as this bird is thought to occur over a range of 15,400,000 km (5,950,000 sq mi). This bird is vulnerable to introduced mammalian predators, such as raccoons. The removal of introduced predators from breeding islands allows the species to recover. Climate change has a negative effect on this bird, and reproductive performance decreases with increased temperatures. It is also particularly vulnerable to oil, and adults near oiled shores display symptoms of 1092: 1051: 982: 998:. This guillemot usually retains its nest site, meaning that nest sites are generally used multiple times, although it does not display this behaviour if its mate does not return to breed. The nests are found at a wide range of heights, from about 1 to 55 m (3.3 to 180.4 ft) above sea-level. Nesting sites are defended by established pairs, as is a small territory around the nest entrance of between 1–4 m (11–43 sq ft). Both sexes defend the nesting site, although most defence is done by the male. 82: 1180: 1072: 57: 2601: 1063:
Young birds do not breed until at least three years after fledging, with most first breeding at four years of age. While they may not return to breed, two or three year old birds may start attending the breeding colony before they reach sexual maturity, arriving in the colony after the breeding birds. Pigeon guillemots that reach adulthood have an average life-expectancy of 4.5 years, and the oldest recorded individual lived for 14 years.

and 70 ft). The dives can range from 10 to 144 seconds, and usually average 87 seconds, with an intermission between dives lasting around 98 seconds. Dives of two to ten seconds are typical when feeding on shoals of sandlance at the water's surface. Smaller prey are probably consumed underwater, but larger organisms are brought to the surface to eat after capture.

coastal sea cliffs. In the winter it forages along rocky coasts, often in sheltered coves. Sandy-bottomed water is avoided, presumably because this does not provide the right habitat to feed in. It occasionally can be found further offshore, as far as the continental shelf break. In the Bering Sea and Alaska, it feeds in openings in ice sheets.

34 to 42 days after hatching, although the time taken to fledge has been known to take anywhere from 29 to 54 days. Chicks fledge by leaving the colony and flying to sea, after which they are independent of their parents and receive no post-fledging care. After this, the adult also leaves the colony.

The adult pigeon guillemot requires about 20% of its own weight, or 90 grams (3.2 oz) of food each day. It doubles its rate of fishing when feeding the nestlings. As the nestlings get older, they are fed more, until 11 days after hatching, when the food generally levels out. The food they get,

The pigeon guillemot forages by itself or in small groups, diving underwater for food, usually close to shore and during the breeding season within 1 km (0.6 mi) of the colony. It forages at depths from 6 to 45 m (20 to 148 ft), but it prefers depths between 15 and 20 m (50
