Conservation Low ConcernThick-billed Murre are numerous, but are vulnerable to oil spills and gill-netting. The North American Waterbird Conservation Plan estimates a continental breeding population of 80 million birds, rates the species a 10 out of 20 on the Continental Concern Score, and lists it as a Species of Moderate Concern. Thick-billed Murre is not on the 2014 State of the Birds Watch List. There is little information on population trends. Back to top
