Conservation

Conservation Low ConcernRazorbill populations are currently thought to be stable or increasing throughout major parts of the species' global range. The North American Waterbird Conservation Plan estimates a continental breeding population of 76,000 birds, rates the species a 14 out of 20 on the Continental Concern Score, and lists it as a Species of Moderate Concern. Razorbill is not on the 2014 State of the Birds Watch List. Exploitation by people for food greatly reduced Razorbill populations until the early 20th century. With protection, the species increased.
