Scruffy

Unlike other wrens that typically hide in vegetation, the Cactus Wren seems to have no fear. They perch atop cacti and other shrubs to announce their presence and forage out in the open. They do not cock their tails over their back the way other wrens do. Instead they fan their tail feathers, flashing white tail tips.  -from All About Birds

Like other desert-dwelling birds such as the Bendire’s Thrasher and Scaled Quail, the Cactus Wren gets almost all of its hydration from the food it eats. Individuals usually forage for food on the ground, probing under leaves and ground litter with their long, curved beaks in search of insects such as grasshoppers, beetles, and wasps. They also consume fruit, seeds, and even small lizards.

These resourceful birds deal with their scorching surroundings by changing their feeding behavior as temperatures climb throughout the day. On cooler mornings, Cactus Wrens forage on the ground in the open. As temperatures rise, they shift their feeding to shady, cooler areas under cover, including in large, thorny shrubs and cacti. During particularly hot afternoons, the birds take a break to rest in the shade.  -from the American Bird Conservancy
