Pigeon Guillemots, scientifically known as Cepphus columba, are medium-sized seabirds that are part of the auk family. Adults usually measure between 12 to 14 inches in length, making them relatively small compared to other seabird species. Yet despite their small size, they command attention with their unique appearance and intriguing behaviors.
The body shape of the Pigeon Guillemot is best described as stout and rounded. Their wings, while somewhat short for a bird, are perfectly adapted for their life in and around the sea. The wings are pointed, aiding them in their underwater pursuits. Their tail is short and rounded, contributing to their overall compact appearance.
A striking feature of the Pigeon Guillemot is its bill, which is thin and sharp. The bill is well-suited for catching and holding onto their prey, typically small fish and marine invertebrates. It's also worth noting their webbed feet, which sit far back on their bodies, aiding in efficient diving and swimming underwater.
Looking at a Pigeon Guillemot, you'd be intrigued by their legs, which are strong, set far back, and have large, webbed feet. These feet are not just a distinctive physical trait, they play a crucial role in the bird's ability to dive and swim underwater, making the Pigeon Guillemot an efficient predator in its marine environment.
In terms of weight, Pigeon Guillemots are typically around 1.1 to 1.4 pounds. This weight, combined with their body design, ensures they are buoyant in water but can also dive to impressive depths when hunting for food. This duality is part of what makes the Pigeon Guillemot a truly fascinating bird to study and observe.

Pigeon Guillemots are a study in contrast when it comes to their color pattern. During the breeding season, they exhibit a striking black or dark chocolate-brown plumage across their body. This dark color provides an appealing contrast to their bright red feet, which are often noticeable when they are perched on the rocky cliffs of their coastal homes.
Another intriguing color feature of the Pigeon Guillemot is the white patch on their wings. Even in flight, these patches are visible against the dark body, giving the Guillemot a distinctive look. This white wing patch is seen in both the upperwing and underwing, making the bird easily identifiable even from a distance.
In contrast to their dark summer attire, Pigeon Guillemots go through a dramatic color change during the non-breeding season. They molt into a predominantly white plumage with dark spots, a transformation that often leaves observers amazed. This plumage serves as excellent camouflage, helping them blend with the snowy and icy environments during winter.
One must not overlook the Pigeon Guillemot's bright red mouth lining, which is particularly noticeable when they yawn or call. This adds another level of charm to their overall appearance, making them one of the most charismatic seabirds you can come across in the Pacific region.
The bird's eyes also command attention - they are dark, contrasting beautifully with the surrounding plumage. The eyes, coupled with their overall color pattern, lend the Pigeon Guillemot a distinctive, charismatic appearance that is hard to forget once seen.

Understanding the behavior of the Pigeon Guillemot provides a fascinating window into their adaptations and life strategies. These birds are known for their marine lifestyle, spending a significant amount of their time at sea. They are excellent divers, able to dive up to 150 feet below the surface in search of food.
Pigeon Guillemots are also sociable birds. During the breeding season, they nest in colonies on rocky cliffs or offshore islands. The sight of these birds occupying every available nook and cranny on these cliffs is a sight to behold, showcasing their communal nesting behavior.
Feeding behavior in Pigeon Guillemots is another aspect that sets them apart. They dive underwater in search of their prey, using their wings to 'fly' under the surface. They primarily feed on small fish and marine invertebrates, showcasing an impressive hunting skill that is vital to their survival in their marine habitats.
When it comes to mating behavior, Pigeon Guillemots form monogamous pairs that return to the same breeding site year after year. This nesting fidelity, along with their intriguing courtship displays, add to their behavioral uniqueness. The male performs an intricate dance, both in the air and on the water, to woo the female, a spectacle that often captivates observers.
Despite their mostly marine lifestyle, Pigeon Guillemots are also known to spend time on land, especially during the breeding season. On land, they can appear somewhat awkward due to their body structure and the position of their legs. However, once they hit the water, they transform into agile swimmers and divers, exhibiting an astonishing
Pigeon Guillemots are a marine species through and through. They inhabit the temperate and subarctic waters of the North Pacific, spanning from the coastlines of Eastern Siberia to California. During the breeding season, they are commonly found in rocky coastal areas and offshore islands, where they nest in rocky crevices or burrows.
These birds are not limited to any specific altitude and can be found at sea level and above. They prefer areas with rocky substrates both for nesting and for perching. They're often seen on rocks near the water, where they rest, preen, and interact with each other.
During the non-breeding season, Pigeon Guillemots move further out to sea. However, they generally stay close to shore, often within a few miles. They are particularly attracted to areas with abundant food supply, including places where upwellings bring nutrients to the surface, resulting in an abundance of fish and invertebrates.
Pigeon Guillemots have also been known to inhabit human-made structures such as docks and bridges, as long as these are in close proximity to their favored marine environments. These adaptations to various habitats demonstrate the bird's flexibility and resilience, qualities that have enabled it to thrive despite changes in its natural environment.
Given the Pigeon Guillemot's preference for coastal and marine environments, it is no surprise that they are directly affected by changes in these ecosystems. Issues like pollution, overfishing, and climate change, which alter their habitats and food availability, have an impact on the Pigeon Guillemot populations, making the study of their habitat preferences and requirements critical for their conservation.
