Common Murre are numerous, but vulnerable to oil spills and gill-netting. The North American Waterbird Conservation Plan estimates a population of 4,250,000 in North America, rates the species an 11 out of 20 on the Continental Concern Score, and lists it as a Species of Moderate Concern. They are not on the 2014 State of the Birds Watch List. Pacific populations have declined and partially recovered, while Atlantic populations appear to be increasing.Back to top
