This unmistakable warbler is found in canyons and mountainous areas with oaks and pines. Striking plumage: black with large white wing patch and red belly. Tail is often fanned and flashed while foraging, revealing bold white outer tail feathers. Very active, usually flitting around in the lower to mid-levels of trees. Listen for a musical warble with repeated “chewee” notes. Call is similar to Pine Siskin but less wiry. Primarily a Mexican species, occurring as far south as northern Nicaragua. Breeding range barely extends into the southwest U.S.
