Conservation Low ConcernRhinoceros Auklets are found along the west coast of North America and in Asia. The North American Waterbird Conservation Plan estimates a continental breeding population of 922,000 birds, rates the species a 10 out of 20 on the Continental Concern Score, and lists it as a Species of Low Concern. Rhinoceros Auklet is not on the 2014 State of the Birds Watch List. These birds are vulnerable to the effects of oil spills. Raccoons and other introduced mammals have caused catastrophic population losses and possibly the total elimination of some colonies.Back to top
