21-4-2024 BANDHAVGARH, INDIA - ORIENTAL GARDEN LIZARD (Calotes versicolor)

The Oriental garden lizard (Calotes versicolor) is an agamid lizard found in indo-Malaya. It has also been introduced in many other parts of the world. The Oriental garden lizard is an insectivore and the male gets a bright red throat in the breeding season.

The coloration of this lizard is very variable, sometimes uniform brownish or greyish-olive or yellowish. There are usually broad brown bands across the back, interrupted by a yellowish lateral band. Black streaks radiate from the eye, and some of them are continued over the throat, running obliquely backward, belly frequently with greyish longitudinal stripes, one along the median line being the most distinct; young and half-grown specimens have a dark, black-edged band across the inter-orbital region. During the breeding season, the male's head and shoulders turns bright orange to crimson and his throat black. Males also turn red-headed after a successful battle with rivals. Both males and females have a crest from the head to nearly the tail, hence their other common name, "crested tree lizard".

Oriental garden lizards occur in SE Iran, Afghanistan, Bangladesh, Bhutan, Cambodia, China (South) (Yunnan, Guangdong, Guangxi, Hong Kong, Hainan Island), India (including the Andaman Islands), Indonesia (Sumatra), Malaysia (Western), Maldives, Mauritius (Reunion, Rodrigues), Myanmar, Nepal, Pakistan, Philippines, Sri Lanka (Ceylon), Thailand, Vietnam (including Pulo Condore Island). These lizards are found in a wide range of habitats and appear to adapt well to humans. They are commonly found among the undergrowth in open habitats including highly urban areas.

25-11-2016 JURONG, SINGAPORE - ORIENTAL GARDEN LIZARD (Calotes versicolor)

The oriental garden lizard (Calotes versicolor), also called the eastern garden lizard, Indian garden lizard, common garden lizard, bloodsucker or changeable lizard, is an agamid lizard found widely distributed in Indo-Malaya. It has also been introduced in many other parts of the world.

The native range of the species includes southeastern Iran, Afghanistan, Bangladesh, Bhutan, Cambodia, India (including the Andaman Islands), Indonesia (Sumatra), Malaysia (Western), Maldives, Mauritius (Reunion, Rodrigues), Myanmar, Nepal, Pakistan, Philippines, Sri Lanka (Ceylon), Thailand, Vietnam (including Pulo Condore Island). It has been introduced to Brunei, Celebes, Oman, Seychelles, Singapore and United States. The lizards were introduced to Singapore from Malaysia and Thailand in the 1980s. In Singapore, they are a threat to the native green-crested Lizard. The changeable lizard is relatively common and found in a wide range of habitats. They appear to adapt well to humans and are thus not endangered. They are commonly found among undergrowth, in open habitats as well as highly urban areas. However, in China people regularly kill them, as they are viewed as pests.

Changeable lizards also occasionally consume vegetable matter.

Males become highly territorial during breeding season. They discourage intruding males by brightening their red heads and doing "push-ups". Each tries to attract a female by inflating his throat and drawing attention to his handsomely colored head. Oviparous; about 10—20 eggs are laid, buried in moist soil. The eggs are long, spindle-shaped and covered with a leathery skin. They hatch in about 6–7 weeks. They are able to breed at about 1 year old.
