Range. - North America west of the Rocky Mountains; north to British Colum bia; winters south of the United States.

Similar in size and appearance to the Ruby-throat, but with the chin and upper throat black, the rest of the throat gorget being violet or amethyst. It is an abundant species in summer in many localities, especially in the southern half of its range. They build their nests at low elevations, rarely above ten feet, on small branches or the fork at the end of a limb. The nests are made of yellowish plant fibres and are not covered with lichens, so that they have a peculiar spongy appearance. Eggs indistinguishable from those of the Ruby-throat. Laid during April, May or June.
