Description
The little Auk is a charming and memorable seabird found in the Arctic and sub-Arctic regions. Despite its small size, it fearlessly dives into the icy waters in pursuit of its prey. Its distinct look, featuring a rounded head, black and white feathers, and a plump body, makes it stand out.

Feeding Habits
Little Auk forages by diving underwater, propelling with wings, and steering with feet. They eat planktonic crustaceans, especially copepods, plus amphipods, euphausiids, pteropods and juvenile fishes. They dive down to 100 feet and use a zig-zag ascent pattern. They may feed nocturnally and transport food over 60 miles for chicks using a throat pouch.
Habitat
Little Auk predominantly reside in High Arctic oceanic environments, including coastal cliffs and rocky isles. Their habitat is characterized by strong currents and nutrient-rich waters necessary for feeding, especially near sea ice edges. During the non-breeding season, they migrate to southward continental shelf edges, with some overwintering in polynyas to ensure continuous access to prey.
Nest Behavior
Little Auk engages in nesting activities in their chosen sites, laying eggs on the minimalistic pebble beds. Both parents participate in incubating the eggs and rearing the young.
Nest Characteristics
Little Auk typically nests in rocky crevices 1–3 feet deep on cliffs and islands, creating a simple platform of pebbles, occasionally adorned with lichen or grasses.

Behavior
Little Auk exhibit sociable behavior year-round. They congregate in vast numbers preceding the breeding period, engaging in group flights and vocalizations, especially during low light. These behaviors persist throughout nesting, with peak intensities at dawn and dusk. Little Auk tend towards monogamy, commonly reuniting with prior season mates. Their charming courtship includes head gestures, bill touching, and slow wingbeats resembling 'butterfly' flights. Both parents equally participate in egg incubation and chick nurturing. Immature, non-breeding little Auk form 'clubs' within colonies. Post-fledging, little Auk migrate south in large groups, maintaining flock cohesion throughout the winter.
Species Status
Although populations appear to be decreasing, this is not currently thought to be rapid enough to be of concern for the species in the medium term, especially as global little auk numbers are generally rather fluid. Little auks have been shown to be able to buffer fluctuations in prey availability, caused by climate change, via plasticity in their foraging behavior, which is likely to make accurate conservation assessments more difficult.
