Wikipedia Abstract

The olive sparrow (Arremonops rufivirgatus) is a species of American sparrow in the family Emberizidae. (Other names include green finch and Texas sparrow.) Its range includes Belize, Costa Rica, Guatemala, Honduras, Mexico, Nicaragua and southern Texas (including the counties of Val Verde, Atascosa, and Nueces). The olive sparrow does not migrate, and is resident in thickets, chaparral, and undergrowth near forests, from sea level to 6,000 feet (1,800 m). Males sing unmusical chip notes similar to the swamp sparrow.
