Pigeon Guillemot

The pigeon guillemot is usually found in small colonies of under 50 birds or in isolated pairs.This species maintains pair bonds for multiple breeding seasons. Those breeding in the northernmost part of its range in Alaska move south in the winter. Those from the center of its range (from British Columbia to Oregon) may remain in that region. California pigeon guillemots move north after breeding, as far north as British Columbia.

The Pigeon guillemot breeds on rocky islands and on mainland cliffs away from predators. This species first breeds once they reach 3 to 5 years. They usually lay 1 to 2 eggs which are creamy to pale-blue green with gray and brown blotches. Both males and females sit on the eggs. This incubation period lasts about 26 to 32 days.

Once hatched, the young pigeon guillemot remains in the nest for 29 to 54 days where both parents bring them small fish. As they leave the nest they make their way down to the water, already able to swim and dive, though they are not strong fliers for another 2 to 3 weeks.
