Balcones Canyonlands National Wildlife Refuge

Balcones Canyonlands is a national wildlife refuge located in the Texas Hill Country to the northwest of Lago Vista, Texas. The refuge was formed in 1992 to conserve habitat for two endangered songbirds, the golden-cheeked warbler (Setophaga chrysoparia) and the black-capped vireo (Vireo atricapilla), and to preserve Texas Hill Country habitat for numerous other wildlife species.
