Adelie Penguin (Pygoscelis adeliae)

The Adelie Penguin (Pygoscelis adeliae) is, together with the Emperor Penguin, one of the only two types of penguin living on the Antarctic mainland. This species is common along the entire Antarctic coast and nearby islands. Adelie penguins are the smallest of the penguins living on the Antarctica continent. Adelie penguins were named after the wife of a French explorer in the 1830s.

Adelie penguins nest and breed on the rocky, ice-free beaches in large colonies of ten thousands of birds. There are over 2.5 million breeding pairs living in the Antarctica region.

Adelie Penguin Characteristics

Adelie Penguin

Adelie penguins are 60 to 70 centimetres long and around 4 kilograms in weight.

Distinctive marks are the white ring surrounding the eye and the feathers at the base of the bill.

These long feathers hide most of their red bill. Their tails are a little bit longer than other penguins tails.

Adelie Penguin Diet

Adelie penguins are highly dependant on crustaceans, such as krill. Fish and amphipods can also be common foods in certain locations during certain seasons.

Adelie Penguin Reproduction

Adelie penguins arrive at their breeding grounds in October. Their nests consist of stones piled together. The male Adelie penguins summon the females with a low guttural noise followed by a loud cry. A female Adelie penguin typically lays two eggs which are brown or green in colour.

In December, the warmest month in Antarctica (about -2°C), the parents alternate periods of incubating the egg. One parent goes to feed and the other stays to warm the egg. The parent who is incubating does not eat. In March, the adults and their young return to the sea. Adelie penguins have to defend their nests from other penguins who try to steal pebbles, stones, and other nest building materials. Adelie penguins do not drink water but instead, they eat snow. They have a gland in their nose that takes the salt out of the ocean water that they swallow when catching fish and eating fish while in the water.

Adelie Penguin Migration

Adelie Penguins are migratory penguins and after breeding, they do not return to their colonies until the next spring. Little is know about the non-breeding distribution of this species. There are only a few records of Adelie Penguins during the Antarctic winter.

Recent work using satellite telemetry indicates that Adelie Penguins from the Ross Sea leave this area in autumn and migrate about 600 kilometres north of the Antarctic continent. Juveniles are suspected to travel even further north than adults.
