Family: Troglodytidae
Genus: Campylorhynchus
Species: Campylorhynchus brunneicapillus
Subspecies: C. b. couesi (Sharpe, 1882)

Identification

C. b. couesi can be identified by its large size compared to other cactus wren subspecies. It has pale underparts and lacks streaking on the throat. The upperparts are cinnamon-brown and the wings and tail are barred with black. The bill is long and downward curved.

Location

The range of C. b. couesi includes Nevada, Utah, Arizona, New Mexico, Texas, Sonora, and Chihuahua. It is found in arid environments including deserts and canyonlands. Its habitat consists of areas with stands of tall cacti, especially saguaro cactus.

Interesting Facts

Distinctive Nesting Habits: Cactus Wrens, including the C. b. couesi subspecies are known for building unique globe-shaped nests in cacti, providing protection against predators and extreme weather conditions.

Vocalization: C. b. couesi has a melodious and complex song, often heard echoing in the arid landscapes it inhabits.

Adaptability: These wrens have adapted remarkably well to arid and desert environments, displaying impressive survival skills.

Status

The cactus wren is not considered threatened overall. However, some local populations in the southwest have declined due to habitat loss. Urbanization and conversion of land for agriculture have reduced cactus wren habitat.

Conservation of Natural Habitat

Protecting stands of cacti, especially saguaros, is important for conserving cactus wren populations. Limiting development in desert ecosystems and creating protected areas will help maintain habitat. Removing invasive plant species that compete with native cacti is also beneficial.
