Canon Rebel XSI – Lens Canon 100 – 400 mm
Hoover Dam, Las Vegas, Nevada USA
With a little help from my husband and my trusty big lens I get to share this gorgeous fellow with you. He was a little skittish but settled back down to take in the sun. Snow at home but + 26 there. Pretty boy isn’t he.
Family: Iguanidae Order: Squamata Class: Reptilia
The chuckwalla is widely distributed throughout most of the Mojave, Sonoran and Colorado deserts from sea level to 1400 m (4600 ft) (Macey and Papenfuss 1991). It is found in a variety of desert woodland and scrub habitats but is most frequently associated with, and reaches highest densities, in creosote communities. It is restricted to areas with large rocks, boulder piles, or large rock outcrops on slopes. It is less frequently found on flats. This lizard is active from mid-spring to mid-summer and occasionally in fall. Densities of chuckwallas have ranged from 7 to 14 per ha (3 to 6 per ac) (Shaw 1939, Stebbins 1954, Johnson 1965, Nagy 1971, Berry 1974).
