Non-Migrant: Yes. At least some populations of this species do not make significant seasonal migrations. Juvenile dispersal is not considered a migration.
Locally Migrant: No. No populations of this species make local extended movements (generally less than 200 km) at particular times of the year (e.g., to breeding or wintering grounds, to hibernation sites).
Locally Migrant: No. No populations of this species make annual migrations of over 200 km.
Home range size and movements seem quite variable. Munger (1984a) found that single-season home range size in southern Arizona averaged 1.3 ha in females and 2.4 ha in males. Home range length extended up to about 400 m but often was 100-300 m, and some individuals that were observed more than 30 times moved over an area less than 55 m across. Some individuals tended not to remain in a limited area. Overlap of home ranges occurred but was not extensive.
In southern New Mexico, home range size was about 1 ha or less (Worthington 1972). Whitford and Bryant (1979) recorded movements of 9-91 m per day (average 47 m) in New Mexico. Individuals followed a zig-zag course and rarely crossed their own path.
In Colorado, Montgomery and Mackessy (in Mackessy 1998) reported that a juvenile moved approximately 100 m in two days. Another juvenile was recaptured 480 m from its original capture location after 47 days.
In Texas, total area of use varied from 291 sq m (25 days) to 14,690 sq m (116 days); weekly home ranges appeared to be mobile (Fair and Henke 1999). Annual adult survival rate was between 9 and 54 percent.
In Oklahoma, average individual daily linear movements for all lizards was 45.0 m (range 10-220 m); males moved significantly farther than females in but not after May when their average daily movements were very similar; average individual daily activity area for all lizards was 232.8 square meters (range 1.7-3011.4 sq m); males covered drastically larger areas in a day during May than did females (Stark et al. 2005).
