Abstract: Garden lizard is currently falling in the red list of endangered reptiles. However the species, Calotes versicolor is trying to protect its racial survival by adopting several environmental strategies which is purely behavioral & scientific observation on the ethology of the garden lizard with respect to its protection needs to be genetically verified & established. Nevertheless, there is evidence that the Calotes versicolor, the lizard, is now established in Madhepura (Bihar), and it is reported to be dispersing away from its original point of introduction. Collected data on its habitats, feeding habits, predators and parasites show that this species is adaptable, prolific and omnivorous, and it is considered to be an invasive alien species that competes with or feeds on native biota in some parts of the Bihar state, such as Purnea and Saharsa. These population need to be studied to prevent their potential ecological threat.
