Conservation

Conservation Red Watch List

LeConte's Trasher populations appear to have declined between 1966 and 2015, according to the North American Breeding Bird Survey. Partners in Flight estimates a global breeding population of 80,000 birds with 80% living in the U.S., and 20% in Mexico. The species rates a 17 out of 20 on the Continental Concern Score and is on the 2016 State of North America's Birds' Watch List, which lists bird species that are most at risk of extinction without significant conservation actions to reverse declines and reduce threats. It is also a U.S.-Canada Stewardship species. LeConte's Thrasher has lost extensive habitat to development in some parts of its range; irrigated lawns, groves, and fields are not compatible with its need for desert vegetation.
