Description
Did you know that the pigeon guillemot can dive up to 150 feet deep to catch its next meal? With striking black-and-white plumage and bright red feet, this daring diver is a true acrobat of the sea, using its wings to "fly" underwater. When they're not busy fishing, these playful seabirds can be spotted performing head-bobbing dances and whistling out their distinctive trills to communicate with their colony.
The pigeon guillemot can weigh between 450to550grams and be from30to38centimeters tall.
The typical lifespan of the Pigeon Guillemot is around 15-20 years. This seabird's lifespan is comparable to related species within the Alcidae family. For instance, the Common Murre also has a lifespan of approximately 20 years, while the Atlantic Puffin can live up to 20-25 years. Pigeon Guillemots reach sexual maturity around 3-5 years of age and continue to breed annually. Like their relatives, they exhibit strong site fidelity, often returning to the same breeding colonies. Their longevity, while moderate, is sustained by relatively stable survival rates in their natural coastal habitats.

How to recognise a pigeon guillemot?
General appearance
The Pigeon Guillemot is a striking bird characterized by its dark, sooty-black plumage, offset by bright white wing patches. These distinctive white wing patches are especially visible in flight. The bird's bill is slender and dark, perfectly adapted for its aquatic lifestyle. During breeding season, the Pigeon Guillemot's legs and feet take on a vivid red hue, contributing to their unique aesthetic. Its compact body and long, pointed wings facilitate efficient diving, allowing it to forage underwater for extended periods.
Male vs female
In Pigeon Guillemots, there is no significant difference between the appearances of males and females. Both sexes display the characteristic black plumage and white wing patches. During the breeding season, both exhibit vibrant red legs, making it challenging to distinguish between the sexes based on external appearance alone. Observers must rely on behavioral cues rather than physical differences to differentiate males from females.
Juvenile
Juvenile Pigeon Guillemots are distinguishable by their more muted coloration compared to adults. They have a grayish-black plumage with less defined white wing patches. The red coloring of the legs and feet, prominent in adults during the breeding season, is also less vibrant in juveniles. As they mature, their plumage gradually transforms, taking on the deep black and white characteristics of fully matured adults. Monitoring these changes provides valuable insight into the development stages of this seabird species.
Breeding and nesting habits of the pigeon guillemot
Mating Behaviors
Pigeon Guillemots engage in various courtship displays and vocalizations to attract mates during the breeding season. Adults exhibit synchronized swimming, chasing, and wing flapping to signal their readiness to mate. Unlike many seabirds, they tend to form monogamous pairs and return to the same mate each year if possible.
Nesting Details
Nesting primarily occurs on rocky shores, cliffs, and coastal structures. They prefer secluded crevices or burrows that provide shelter from predators and harsh weather. Nest materials are minimal, often just a few pebbles. Pigeon Guillemots do not typically nest in gardens but creating rock piles or installing artificial nest boxes near coastal areas might encourage nesting.
Eggs and Chick-rearing
Mating pairs lay one to two eggs per clutch, typically between April and July. The incubation period lasts about 28 to 32 days, during which both parents share duties. Once hatched, the chicks remain in the nest for approximately 30 to 40 days, receiving regurgitated fish from both parents several times a day. By the end of this period, fledglings are capable of independent feeding and flight.
What does a pigeon guillemot like to eat?
Natural diet
The Pigeon Guillemot is primarily a seabird, and its diet mainly consists of marine food sources. In the wild, they feed largely on fish such as blennies, sculpins, and other small to mid-sized species, which they catch by diving beneath the water's surface. Their diet also includes marine invertebrates like crustaceans and mollusks. Seasonal variations exist, with certain prey types becoming more abundant at different times of the year. During breeding season, they may target fish that provide high energy content needed for raising their young.
Bird feeders
Bird feeders are not commonly frequented by Pigeon Guillemots, as their dietary needs are specific to the marine environment. Unlike passerine birds, they don't typically consume seeds or common feeder offerings. These seabirds usually do not adapt their foraging habits to human-provided sources, as they rely primarily on their skill in diving for underwater prey. While there are limited reports of them visiting feeders, it is generally recommended to appreciate these birds in their natural coastal habitats rather than attempting to attract them with non-marine offerings.
Create a welcoming environment with the right feeder
To attract Pigeon Guillemots, consider using feeders designed with platforms or trays, as these birds prefer to feed on flat surfaces. This feeder type allows them to comfortably perch while they dine. Position the feeder within reach but away from busy areas, providing a sense of security and comfort in your backyard.
Offer scrumptious bird-friendly snacks
Pigeon Guillemots are partial to seafood, so entice them with meal choices that include whole grain and millet. Use Bird Buddy seeds, a high-quality blend that mimics their natural diet, to keep them coming back. Providing nutrition that aligns with their shoreline dining habits encourages consistent visits.
Optimum placement for year-round visits
Position your feeder near water features or shaded areas, particularly within sight of nesting boxes or shrubs. Placing the feeder about 5 to 10 feet off the ground strikes a balance between accessibility and predator safety. This positioning helps create a sense of natural habitat, inviting these birds regularly.
Consider the seasons
Pigeon Guillemots have varying needs throughout the year, especially during breeding season. In spring and summer, they look for ample food to raise their young, so keep your feeder stocked. In winter, offer suet or high-energy choices to help them maintain energy levels.
Enhance your yard with water and safe havens
Guillemots are naturally drawn to water. Installing birdbaths or small ponds provides an essential resource for drinking and cooling off. Additionally, incorporating dense shrubs or nesting boxes nearby creates a comfortable retreat, making your backyard a safe and attractive spot for these charismatic birds.
Where can you find pigeon guillemots?
Primary habitat
The Pigeon Guillemot prefers coastal environments, inhabiting rocky shores and coastal cliffs across the North Pacific, from Alaska to California. They thrive in temperate climates where they can nest in crevices or burrows. Their typical range includes the Aleutian Islands, British Columbia, and the Kuril Islands.
Additional range
Although primarily coastal, Pigeon Guillemots occasionally venture into brackish estuaries and harbors. They are adaptable to varying sea conditions, sometimes found in inland waters during harsh weather. Their resilience allows them to inhabit less typical rocky environments when necessary.
Do they migrate?
The Pigeon Guillemot (Cepphus columba) exhibits varied migratory habits depending on its geographical location. In general, populations in the northern part of their range, such as those in Alaska, may migrate short distances. They typically move southward to avoid harsh winter conditions, relocating to ice-free coastal waters. These migrations are not extensive. For example, Alaskan populations may travel only as far as the northern parts of British Columbia and Washington. Migration generally occurs between September and November as the birds seek out areas with open water and abundant food. However, other Pigeon Guillemot populations remain resident year-round, especially those residing in more temperate parts of their range such as California. These birds often stay near their breeding sites along rocky coastlines or steep cliffs, where they have reliable access to food throughout the year. Key locations for wintering include protected coastal bays and inlets where tidal currents maintain ice-free waters. Return migration to breeding sites typically begins in March and April, with birds re-establishing territories and nesting pairs soon after arriving. Overall, Pigeon Guillemots adapt their migratory behaviors to their local environmental conditions and food availability.
What is the role of pigeon guillemots in nature and how to protect them?
Conservation status
The Pigeon Guillemot is generally considered common, with a stable population trend, and is not currently listed as vulnerable or endangered. Key conservation efforts focus on protecting its coastal habitats, particularly from oil spills and pollution. Significant threats include climate change impacts, such as sea temperature shifts and food supply changes, as well as human disturbances and predation by introduced species like rats and foxes. Conservationists emphasize monitoring populations and mitigating these threats to ensure the birds remain abundant.
Ecological role of pigeon guillemots
Its role in the ecosystem
The Pigeon Guillemot (Cepphus columba) plays a vital role in the ecosystem primarily as a predator in its coastal habitats. By feeding on small fish, marine invertebrates, and crustaceans, this bird helps regulate the populations of these species, preventing overpopulation that could lead to imbalances in the marine food web. The predation pressure they exert on small fish can help maintain species diversity and ensure the stability of marine ecosystems. Pigeon Guillemots contribute to nutrient cycling within their ecosystem. By excreting waste on land, particularly near their nesting sites in rocky coastal regions, they transport nutrients from the ocean to terrestrial environments. This waste acts as a natural fertilizer, enriching the soil and contributing to the growth of coastal vegetation. Their interactions with other species include acting as prey for larger birds of prey and mammals, thus supporting higher trophic levels. Additionally, their nesting habits in burrows or cliff crevices can influence the structure of the coastal environment by disturbing soil and rocks, which may impact other organisms that share the habitat. These ecological interactions underscore the Pigeon Guillemot’s importance in maintaining both marine and coastal ecosystem balance.
