Chestnut-bellied Sandgrouse - Jubail

Whilst birding the Jubail area 12 February, Phil Roberts and I saw a Chestnut-bellied Sandgrouse Pterocles exustus. This was a new species for the Eastern Province for me although Phil had seen one previously. They are a common and widespread breeding resident on the Tihamah and southern Red Sea coastlands, less common in the Northern Hejaz north to Rabigh with all records below 1000 metres. The species is, however, rare in Central Saudi Arabia and had not been recorded in the Eastern Province until 2013 when I was sent a photograph showing a number of birds (unfortunately) shot, apparently near Al Hassa in 2013. Phil Roberts then saw a single bird at Sabkhat Al Fasl in 2014 and this record from Jubail is only the third for the Eastern Province. Unfortunately the bird flew before we could get any photos so the photograph below is of one I saw at Sabya Waste Water Treatment Pools, near Jizan in the southwest of the Kingdom. They are a relatively small species, with elongated central tail feathers, dark underwing, blackish belly and unmarked head. The male has a narrow pectoral band and chestnut brown belly darkening towards rear, whereas the female is more mottled above and shows a tricoloured ventral pattern. Races differ mainly in tone of upperpart coloration with the Arabian population P. e. erlangeri sandy coloured. They typically inhabit bare semi-desert, often with scattered thorny scrubs or trees including Acacia. They feed during the cooler hours of morning and afternoon and drink 2–3 hours after sunrise, while in very hot weather some individuals drink again before sunset.
