Black-tailed Gnatcatchers are often heard before they are seen, because they favor the thickest parts of desert scrub. They forage for small insects among thorns and leaves, and will come out into the open to investigate or scold an intruder.
- Habitat
Look for Black-tailed Gnatcatchers in desert scrub, including washes densely lined with creosote and salt bush as well as areas studded with ocotillo, prickly pear, cholla, and mesquite.
