Collared lizards are patterned in beautiful colors. As so often in the animal Kingdom, the males have more spectacular coloring than the plainer females. You can easily see that the creatures owe their name to the markings on their neck. Collared lizards live in Rocky, arid regions in the southwestern area of the United States and Mexico. Males like to keep a watchful eye on their territory from a high Vantage point. Any other males are vigorously driven away with a few threatening gestures or, if it comes to it, a couple of bites. Still, they have no objection to several females congregating in their territory. Collared lizards eat small vertebrates, insects, leaves and fruit. Collared lizards are pretty to look at and are sociable, cheerful animals. Many people like to keep them in a terrarium. But whoever wants to look after these sensitive animals needs to know a lot about them. Otherwise, the situation can quickly turn toward animal cruelty.
