Grey Francolin – Salwa area

Grey Francolin is a scarce breeding resident in Saudi Arabia with the first known record at Safwa on 18 November 1991 since when records were reported locally from Dhahran to Jubail in coastal areas with one in coastal sand dunes at Jubail from at least 12 September to 16 October 2000 and another at Sabkha al-Fasl 19 January 2004. Range expansion was mapped and thought likely to occur to the north of Jubail and east of Dhahran by Jennings 2010, but records actually declined sharply as it apparently failed to establish a self-sustaining population with the only record known since 2004, a sighting 12 March 2019 just outside Berri Gas Plant, Jubail. A thriving population was found in spring 2021 by Greg Askew, near Salwa, close to the Qatar border and have been seen again in October by myself and again in late November when Phil Roberts and I located 28 birds. The birds are very timid and generally stay under, or in, the trees where they are occasionally flushed or seen in flight. They call very loudly and often, but seeing them well is another matter. This time we found a couple of birds out in the open and took the below photos. The records from the Eastern Province of Saudi Arabia where probably introduced, but possibly occurred as an overspill from birds introduced and established in Bahrain in 1981, where it is now common. The subspecies is Francolinus pondicerianus mecranensis known as Baluchistan Grey Francolin that occurs in arid south-eastern Iran and southern Pakistan. They are resident from eastern Arabia and Iran, throughout India to Sri Lanka where they occur near sea level in areas with trees, bushes and shrubs, including plantations, large parks, cultivated areas, or dry open woodland.

Red-eyed Dove - Jebal Faifa

Jebal Faifa is a tall mountain near the Yemen border and has become a popular tourist resort. The roads to the top are narrow and very steep but there are a number of places to stay at the top. It has recently become a good place to see Red-eyed Dove a species that is claimed widely in Saudi Arabia but one I have personally not seen. It occurs widely throughout Africa south of the Sahara as well as in southwest Arabia (southwest Saudi Arabia and Yemen). It is sometimes common where it is found but it is scarce and local in Saudi Arabia where it is regarded as a resident. It is mainly found in well wooded sites on hillsides, often with gardens with large trees and running water. I went to Jebal Faifa with Phil Roberts in mid-November and stayed at the very top of the mountain. We arrived in the middle of the day and there was very little bird activity except for an unexpected Tihama Shikra flying over near the top. In the late afternoon bird activity started to become more obvious and a number of Red-eyed Dove were heard calling. We slowly worked our way towards where the birds were calling from but the steep hillsides made it difficult getting close. We decided to sit and wait near a small roadside overlooking a steep valley and were rewarded after a short wait by four birds flying in and landing on some overhead wires. We slowly moved closed and were able to obtain some reasonable photos, and counted nine birds in total that evening. On the drive down the mountain the following morning birds were seen regularly on overhead wires almost all the way to the bottom. Other mountain birds seen in the area included Steppe Buzzard & Fan-tailed Raven

Fulvescens Greater Spotted Eagle & Eastern Imperial Eagle – Jubail

Whilst birding the Jubail area in late November we came across two eagles sitting on a power line mast. One was a fulvescens Greater Spotted Eagle, with this colour type being very uncommon making up a maximum of 3% of the birds seen in the Middle East. Fulvescens is more common in the Middle East than in any other area where it occurs, and when you think how uncommon the species is on a world scale there are not that many fulvescens about worldwide. Greater Spotted Eagle is a regular winter visitor to the Juabil area where up to 15 have been recorded on a single day, but only the occasional fulvensens type are noted, although they are seen most years. The other bird was an immature Eastern Imperial Eagle that was much bigger in size with a much larger bill. The Eastern Imperial Eagle is an uncommon winter visitor to Saudi Arabia with most records coming from the north of the country where they are generally seen inland rather than near the coast. The species breeds from Eastern Europe across Asia to China and winters in the Middle East, east Africa south to Tanzania, the Arabian Peninsula, India, and from Thailand to Korea. Currently Eastern Imperial Eagle is listed as vulnerable on the IUCN Red List as it has a small global population and is likely to be undergoing continuing declines, primarily as a result of habitat loss and degradation, persecution and prey depletion. Eastern Imperial Eagle is much scarcer than Greater Spotted Eagle in Jubail but birds are seen almost every year. This particular Eastern Imperial Eagle has been around for almost a month which is unusual as normally they are only seen on single days.

Wadi Disah

Wadi Al-Disah (Wadi Qaraqir) is located in the Tabuk region and is one of the most famous natural tourist attractions. The valley is located about 220 kilometres, by car, south of Tabuk city and is a 15 kilometer long canyon. It is dominated by striking red pillar-shaped mountains, under which trees, including palms and citrus trees are found and affording excellent photographic opportunities.  The weather in the valley is mild throughout the year and it has permanent water. The valley’s Nabataean façade, rock-carved tombs and some well-preserved rock petroglyphs add to the Wadi’s charm.

Black Kite - Abu Arish Municipal Dump

Whilst birding the Abu Arish Municipal Dump in mid-November we found up to 250 Black Kites, with more than 650 in the entire area. It was an amazing spectacle watching hundreds of Black Kites swirling around the rubbish dump, with some birds right overhead and many others on the ground. Some birds looked like typical Black Kites which are a medium-sized bird of prey that is a widespread species throughout the temperate and tropical parts of Eurasia and parts of Australasia. The two sub-species, European Black Kite & Black-eared Kite with European Black Kite Milvus migrans migrans - Breeds Central, Southern and Eastern Europe to Tien Shan and south to NW Pakistan. Winters in sub-Saharan Africa. Black-eared Kite Milvus migrans lineatus - Siberia to Amurland South around Himalaya to Iran, Northern India, Northern Indochina and Southern China; Japan. Recent DNA work suggests that the Black-eared Kite (M. m. lineatus), is not sufficiently distinctive to justify specific status. The status varys throughout Saudi Arabia, where in the east they are uncommon passage migrants, mainly in the spring, and winter visitors, whereas in the west they are common to very common passage migrants and winter visitors occurring from Tabuk in the north and increasing in numbers towards Jizan in the southwest. In central areas it is an uncommon spring and autumn passage migrant and winter visitor that passes in March and again early August to October with wintering birds arriving in November and departing early February.

Blandford’s Agama - Jubail

Whilst birding Jubail I saw a Blandford’s Agama Trapelus ruderatus resting in the top of a small tree. I have seen the species here on a previous visit but they are not often seen, although are probably common. They range from northeast Jordan and southern Syria, through northern and eastern Saudi Arabia, Iraq, Kuwait and southern and central Iran as far south as Shiraz. The species occurs from close to sea level to around 1,000 metres above sea level. It can be moderately common in suitable habitat. This ground-dwelling species is associated with low shrubs (Nitraria) on the fringe of sandy dunes in arid areas and in sandy desert areas. It can sometimes be found perching on bushes but is not found in modified areas. It is very similar to Yellow-spotted Agama Trapelus flavimaculatus but Blanford's Agama has lines on its back that are missing on Yellow-spotted Agama.

Western White Stork - Abu Arish Municipal Dump

On 12 November Phil and I found a Western White Stork ciconia ciconia ciconia feeding on a municipal waste dump on the outskirts of Abu Arish in southwest Saudi Arabia. This is only the second time we have seen the species in Saudi Arabia, with the first a bird we found in Dhahran 17 September 2013. The Western White Stork is a scarce passage migrant and local winter visitor to all areas of Saudi Arabia mostly in autumn. They are usually seen singly or in small numbers, more often in the west of the Kingdom. Birds are thought to pass over the area unnoticed which is borne out by a paper on electrocution and collision of birds with power lines in Saudi Arabia by Mohammed Shobrak (2012) where he recorded 242 dead birds in 2008 with 150 dead birds found on 29 August 2008 alone. The power line surveyed was 100 kilometres south of Jeddah on the west coast of Saudi Arabia. The species is said to winter in the Tihamah, but records are very uncommon from here. The best location appears to be the Abu Arish Municipal Rubbish Dump, where we saw our bird, as 300 were present 9 February 1992 and 100 there December 1999, with one at nearby Malaki Dam Lake (Wadi Jizan Lake) on 7 May 2002 and 15 late October 2002.

Schmidt's Fringed-toed Lizard – Jubail

Whilst briding in Jubail in the summer I found a Schmidt's Fringed-toed Lizard Acanthodactylus schmidti near a wetland area. Schmidt's Fringed-toed Lizard is one of the most abundant species in the genus Acanthodactylus found in Saudi Arabia and occupies sandy plains, dunes and sabkhas (salt flats), particularly in areas of scrubby vegetation. It was named after Karl Patterson Schmidt, with a type locality of Dhahran, Saudi Arabia and it can be distinguished by the exceptionally long fourth toe found on each of its rear feet. As its name suggests it has 'fringes' of elongated scales along the sides of each toe, which are thought to provide better traction on loose sand. It has a light brown or coffee coloured back that is richly speckled with oval-shaped, pale or white spots and can grow to 18 centimetres in length. They have a cylindrical body with smooth, rectangular scales on the belly that are arranged in well-defined rows and scales on the head that are larger than those on the rest of the body. Little is known about the biology of the species but it is thought that its main prey is ants and when prey is located they instantly go rigid, suddenly quiver their tail and strike. It is a diurnal species that digs burrows in the sand among the roots of vegetation and is found throughout the Arabian Peninsula including Saudi Arabia, United Arab Emirates, Jordan, Kuwait, Oman, southeast Iraq and south-west Iran.

Waterbirds - Malaki (Jizan) Dam Lake

Malaki (Jizan) Dam Lake, near Abu Arish is probably the best birding location in the Kingdom and when we were there, we saw quite a few birds including Glossy Ibis, Purple Heron and Hamerkop. Hamerkop is a species that is regularly seen at this location, with it being the best site in the Kingdom to record it. They are quite widespread in the southwest of the Kingdom but very local and uncommon. A good number of Terns were flying over the water including up to ten Whiskered Tern and several Gull-billed Tern. Hundreds of Black Kite were present mainly perched in the trees surrounding the lake but also a few in flight and good numbers of Western Marsh Harrier and a single Greater Spotted Eagle were also located.

Rudist fossil Durania cornupastoris - Thumamah

Whilst looking for fossils near Thummama, near Riyadh, my daughter and I found a number of Rudists fossils of Durania cornupastoris (Des Moulins). They were mainly ventral radial band (Vb) and were found in the Aruma Formation. This formation is distributed in NW-SE direction around Riyadh and consists of three members, from bottom to top, the Khanasir Limestone Member, the Hajajah Limestone Member, and the Lina Shale Member. The rudist biostrome, approximately 2 m thick, is placed in the uppermost part of the Khanasir Limestone Member and consists mainly of Durania specimens. Upper Cretaceous rudists were widely distributed throughout the northern and southern margins of the Mediterranean Tethys. They are described from the Cenomanian–Turonian sequences of Algeria, Tunisia, Egypt, Jordan, and Lebanon and the Campanian–Maastrichtian of Tunisia, Somalia, Oman, UAE, Saudi Arabia, SE Turkey, Iraq, and Iran on the African–Arabian plate. The habitat where they occurred was an inner sublittoral, warm marine paleoenvironment. This paleoenvironment was characterized by firm, stable substrate surfaces subjected to periodically intense wave and current action, within the photic zone, abundant food supply but with minimal terrigenous input. Rudists were a group, now extinct, of box, tube or ring-shaped marine heterodont bivalves that arose during the Late Jurassic and became so diverse during the Cretaceous that they were major reef-building organisms until their complete extinction at the close of the Cretaceous. They lived in shallow marine environments with fossils found in limestone rocks. They had two asymmetric valves with one valve attached to the sea floor. Today, their fossils are found throughout the tropics in the Mediterranean, the Middle East, the Caribbean, and Southeast Asia. Rudists dominated the world of reefs throughout the Cretaceous until the Cretaceous-Tertiary mass extinction event that caused their demise. Rudists grew by accretion (or the increase in size by addition) and were suspension feeders. Generally, large-bodied rudists lived longer and reproduced relatively frequently with small spawns. Rudists lived in shallow ocean waters on the sea floor. These organisms were epifaunal, which means they were usually attached to the sea floor sediment. The clustering and building up of Rudist habitats caused the creation of "Rudist Reefs" which were the dominant reef frameworks in the Cretaceous oceans. Basic external features of rudists include the umbo and thick, asymmetric right and left valves. The umbo is the rounded protrusion found just above the hinge, and the hinge is the pivoting point where the two valves meet. 

Characteristics of rudists include the following:

Unequal valves

One of the valves is usually attached to the sea floor sediment

Hinge structures: free (unattached to sea floor sediment) valve has two teeth and one socket; attached valve has two sockets and one tooth

Two adductor muscles
