Interesting Facts

[ Back to top ]
The cactus wren is an active , inquisitive, and adaptable bird found commonly in most Arizona deserts, making it an appropriate choice for the state bird of Arizona.

A cactus wren often forages for food by overturning moveable objects on the ground with its large curved bill, capturing creatures hiding underneath. Its diet includes ants , beetles, grasshoppers, wasps, fruits, seeds, and an occasional treefrog or lizard.

Size/Age/Growth

About6.5- 8.5 inches long, with a wingspan of 10.75 inches. Adults weigh about 1.4 ounces .

Habitat

Desert areas with taller cacti (especially cholla), or arid hillsides and valleys with other thorny plants capable of supporting their bulky nests . The cactus wren is abundant below 4,000 feet in Arizona, but has been found up to 6,000 feet in New Mexico.[1]

Vegetation: arid lowland scrubs, arid montane scrubs • Maximum Elevation: 2,200 meters • Foraging Strata: Canopy • Center of Abundance: Lower tropical: lowlands, lower than 500 m.; tropics. • Sensitivity to Disturbance: Low

Typically found at an altitude of 0 to 2,809 meters (0 to 9,216 feet).[2]

Diet

A cactus wren often forages for food by overturning moveable objects on the ground with its large curved bill, capturing creatures hiding underneath. Its diet includes ants , beetles, grasshoppers, wasps, fruits, seeds, and an occasional treefrog or lizard.[1]

Reproduction

The female selects the nest site; the nest is often placed in cholla, but also in other cacti and thorny trees and shrubs such as mesquite, ironwood, paloverde, and catclaw acacia. Both the male and female build the nest.[1]

The cactus wren's nest is a large, conspicuous , spherical structure usually built with dry grasses and annual plants ; strips of discarded paper and cloth found along roadsides are frequently woven in. A long, narrow-sided passage into an internal chamber, as well as the thorny substrate, protects this nest from most predators , although eggs and nestlings are frequently taken by coachwhips and whipsnakes in Arizona. As with most wren nests, the nest chamber is usually lined with feathers . In Arizona, Gambel's quail feathers seem to make up the bulk of the lining (a related species, the masked bobwhite, was once thought to be extinct but was rediscovered in Sonora, Mexico, a few decades ago after biologists found its feathers in cactus wren nests and began searching for it). The female cactus wren incubates, starting with the first egg, while the male builds a new nest in preparation for a second clutch . Additional nest structures are constructed and used as roosts throughout the year. The roost nests often lack the feather lining.[1]

During wet winters, breeding season begins as early as late February, allowing time for double and sometimes triple broods. A young cactus wren takes 16 days to hatch and another 19-23 days to fledge ; it will remain dependent on the parents for food for approximately 30 days after leaving the nest.[1]
