Nests are built in cacti (commonly cholla, prickly pear, and saguaro), thorny desert trees, or yucca.[1] Where available, jumping cholla is overwhelmingly preferred.[2][3]:22 Nests average about 0.9 m (3 ft) off the ground,[4] and are usually less than 3.0 m (10 ft) off the ground, but have been recorded as high as 30 ft (9.1 m).
