Definition
-
Aethia pusilla, commonly known as the least auklet, is a species of small seabird belonging to the family Alcidae. It is native to the coastal regions of the northern Pacific Ocean, particularly Alaska, Kamchatka Peninsula, and the Aleutian Islands.
The least auklet is characterized by its diminutive size, measuring around 17 to 20 centimeters in length. It has a rounded body shape, short wings, and a short, stubby bill. The plumage of Aethia pusilla is predominantly dark gray or black, with white underparts and a pale gray patch on the side of the head. During the breeding season, it develops a unique ornamentation of white plumes around the eyes, which enhance its ornamental display.
These seabirds are highly adapted for marine life, possessing webbed feet for efficient swimming and diving. Aethia pusilla primarily feeds on small fish, zooplankton, and invertebrates which it catches by diving underwater. It forms large colonies that nest on rocky cliffs, where it lays a single egg in a small burrow or crevice.
The conservation status of the least auklet is currently considered as a species of least concern by the International Union for Conservation of Nature (IUCN). However, climate change and disturbances to its marine ecosystems pose potential threats to its population. Efforts are being made to monitor and conserve the habitats of Aethia pusilla to ensure its long-term survival.
