Whilst birding the Tanoumah area recently I came across an Anderson’s Rock Agama Acanthocercus adramitanus. This 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 and is the most common species of Agama in Yemen.
It is a common rock dwelling lizard in Saudi Arabia mainly present in mountainous areas and is found to around 2200 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.
