Chinstrap penguins breed in colonies that can range in size from a few dozen to several hundred thousand pairs. They build nests of stones and grass, and the female typically lays two eggs. Both parents incubate the eggs and care for the chicks.
Chinstrap penguins feed on a variety of fish, squid, and krill. They hunt by diving into the water and swimming underwater after their prey. Chinstrap penguins can dive to depths of over 100 meters (328 feet).
The chinstrap penguin is a relatively common species, and its population is estimated to be around 1.5 million breeding pairs. However, the species is threatened by a number of factors, including climate change, habitat loss, and pollution.
