Whilst birding recently in the Jabal Ibrahim area of the western mountains I came across a few Anderson's Rock Agama Acanthocercus adramitanus including this juvenile one. The species is endemic to the Arabian Peninsula, where it is found in west and south Arabia, from Taif (Saudi Arabia) in the north to Dhofar (Oman) in the east. Its range includes Oman, Yemen, and southwestern Saudi Arabia. It is common in Saudi Arabia where it occurs on rocks in mountainous areas and is found to around 2,000 metres above sea level. Populations can be found on vertical rocks, rock steps and amongst boulders often in the vicinity of water. They can occur in precipitous wadis surrounded by dense vegetation, with the animals usually seen on the top of boulders. They do not however require water, obtaining moisture from their insect prey. They are sexually dimorphic, with males often taking on a vivid colouration of blue and orange during display, but a duller light brown with faded orange tail colour when blending in to the environment. The males were very visible due to their bright breeding colours but the females are dull and always stayed high up on the boulders.
