STATUS: Fairly common to uncommon.

HABITAT: Inhabits lush vegetation along wooded streamsides in mountain canyons. In Texas, found among baldcypress, pines, oaks, and bigtooth maples from 4,900 to 7,500 feet in elevation.

SPECIAL HABITAT REQUIREMENTS: Nest sites that are sheltered from rain and sunlight, near an abundance of flowers for feeding, and within a few feet of a stream.

NEST: Builds nest in sites that are completely covered from above, such as in vertical-walled canyons, rock overhangs, on plant stalks, under eaves of buildings, bridges, water towers, and inside buildings. May use the same nest site for several years, adding to the nest each time it is used.
