Conservation Low ConcernCurve-billed Thrasher populations declined by 37% between 1966 and 2015, according to the North American Breeding Bird Survey. Partners in Flight estimates a global breeding population of 3 million, with 36% living in the U.S., and 64% in Mexico. The species rates a 9 out of 20 on the Continental Concern Score. Curve-billed Thrasher is a U.S.-Canada Stewardship species, and is not on the 2016 State of North America's Birds' Watch List. Declines may be due to the loss of habitat to urban development and agriculture.Back to top
