the Cactus Wren is at home in the southwestern deserts. Blazing hot days or freezing cold nights don't faze this
Listed as a Common Bird In Steep Decline* the Cactus Wren is a familiar feature of harsh environments.
Crisp white feathers mimic and complement the sharp white spines of the cholla cactus. At a distance the whites merge into "Nothing Special To Look At Here, Keep Moving."
Conversely, brown tones blend and conceal as light conditions change. The desert habitat is typically shades of olive and dun. Blending into those surroundings is critical to a small bird, even if one is the largest wren.
A ground-foraging, insect-eating Cactus Wren patrols the desert floor to score a meal. He checks under rocks and leaf litter for insects and arthropods. These creatures sustain him so well that he rarely ever drinks. He fulfills his daily moisture needs from the insects he eats. That's a remarkable evolutionary adaptation for this ol'desert bird.
Dangers abound in the desert and the Cactus Wren is not immune to predation from fox, coyote, bobcat, hawks and feral cats. Being able to navigate and nest in these prickly places works to its advantage.
