CONSERVATION STATUS

Least Concern

The Rhinoceros Auklet breeds in the Channel Islands of California, the Aleutian Islands in Alaska, Japan, North Korea and Sakhalin Island in Asia. This species spends its winters in offshore and inshore bodies of water. Nests of the Rhinoceros Auklet are burrows in the soil or natural caves. Because this bird is not good at flying, it prefers to nest on a slight incline to aid in takeoffs. This species is also nocturnal, feeding typically on fish, krill and squid via diving up to 186 feet into the water. The conservation rating for the Rhinoceros Auklet is Least Concern.
