The common collared lizard has the ability to run on its hind legs in order to escape predators, and can reach sprints of up to 15 miles per hour.
This lizard is found in dry desert regions of the southwestern United States and Mexico.
They eat insects, small lizards, and small snakes. During the day, they bask in the sun to gather energy.
Collared lizards are territorial, and males will try to defend their territory in order to have access to as many females for mating as possible.
Males will compete fiercely for mates. Females prefer males with larger heads and brighter coloration. Males perform a complex “dance” to woo females, and receptive females will respond with their own complex movements.
Once babies are born, they are independent and must rely on themselves to find food and hide from predators.
The most well-known member of the Crotaphytus genus, the common collared lizard is known for the striking coloration of males, including a bright turquoise body, yellowish head, and black “collar” markings on the neck. Females also feature the collar markings, but are more muted in their coloration.
The common collared lizard grows up to 15 inches long, including its whip-like tail.
In Oklahoma, the collared lizard is called the “mountain boomer”. The origin of this name is not certain. Some believe it relates to the Gold Rush, when settlers moved west in search of gold. People may have encountered the lizard while hearing strange sounds from canyon winds, mistaking them for the sounds of the lizard.
Collared lizards are kept as pets in some areas.
The collared lizard is a species of Least Concern.
