The Lazuli Bunting, Passerina amoena, is a North American songbird named for the gemstone lapis lazuli. They breed mostly west of the 100th meridian from southern Canada to northern Texas, central New Mexico and Arizona, and southern California. On the Pacific coast their breeding range extends south into extreme northern Baja California. Their habitat is brushy areas and sometimes weedy pastures, generally well-watered, and sometimes in towns.
The Lazuli Bunting is about 5 to 5.5 inches in length. The male is easily recognized by its bright blue head and back. It has white wing bars, light rusty colored breast and white belly. The female is brown, grayer above and warmer underneath. The diet of the Lazuli consists mostly of seeds and insects. They may feed conspicuously on the ground or in bushes, but the singing males are very elusive in treetops. The female lays three to four pale blue eggs in a loose cup nest which it builds.
