Whilst birding the large and extensive
pivot irrigation fields near Tabuk I came across a huge number of Dark Grass
Blue Zizeeria karsandra. Dark Grass Blue is a small butterfly found in
the Southern Mediterranean, in a broad band to India, Sri Lanka, the Andaman
and Nicobar Islands, Burma, Thailand, Malaysia, Indonesia, the Philippines, New
Guinea and northern and eastern Australia. It belongs to the Lycaenids or Blues
family. Most information does not have the speies range in Saudi Arabia but it
has been recorded in the north of the Kingdom from the west side to the east
side.

Black-eared/Black Kites - Tabuk
Whilst birding the pivot irrigation
fields near Tabuk in early October we found hundreds of Black Kites. Many birds
will be on passage at this time of year but many more will saty throughout the
winter. Some birds looked like typical Black Kites and others like the very
similar subspecies Black-eared Kite. The Black Kite is 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 are uncommon to rare migrants, mainly in the spring, and
winter visitors to Saudi Arabia. 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. Northern inland birds
migrate to East Persian Gulf coast and South Asia in winter. Recent DNA studies
(Jeff A. Johnson, Richard T. Watson and David P. Mindell (2005) Prioritising
species conservation: does the Cape Verde kite exist? Proc. R. Soc. B
272:1365–1371) suggests that the Black-eared Kite (M. m. lineatus), is
not sufficiently distinctive to justify specific status. As molecular
information is much more reliable in this species than in the Red Kite, the
Black-eared Kite should be regarded a distinct allopatric subspecies. Another
reason why lineatus and migrans are probably distinct sub-species
is there is a large interbreeding zone in Central Asia, Siberia & Mongolia.
These intergrades may well also occur in Saudi Arabia and as a result the Black
Kite situation in Saudi Arabia is very complicated and many birds are often
best left as unidentified to sub-species level.

Snake-tailed Fringe-toed Lizard - Tabuk
Whilst birdwatching near Tabuk I found a
Snake-tailed Fringe-toed Lizard Acanthodactylus opheodurus. Owing to its
superficial similarity to its larger congener Acanthodactylus boskianus,
the Snake-tailed Fringe-toed Lizard was only described officially in 1980. As
its name suggests, this species has a particularly long tail and, in common
with other Acanthodactylus species, the toes are fringed with scales
adapted for running over loose sand. Like other lacertids, the body is long and
cylindrical, and the legs are well developed, with the animal having a basic
body colour of grey, with seven dark stripes running down the back and sides
and a tail tinged red in immatures. They live in a range of arid habitats,
including plains with relatively hard sand cover and low hills covered by dense
bushes. It is a diurnal lizard and lives in burrows excavated out of hard sand
where it remains concealed for all but a few hours of the day. Their burrows
not only act as a shelter from predators but also provide refuge from extreme
temperatures. The snake-tailed fringe-toed lizard is currently known from the
Arabian Peninsula and several other countries in the Middle East, including
Jordan, Kuwait and Iraq. I thank Mansur Al Fahad for help with the
identification of this record.

Steppe Eagles - Tabuk
Whilst in Tabuk in early October, Phil
Roberts and I came across a number of Steppe Eagles of various ages. We saw at
least five different birds and managed to get good flight views of at least
three birds shown below. It is difficult to know if these birds will winter in
the area or move south to cross into Africa via the Bab El Mandib straights in
Yemen. Steppe Eagle is a common migrant and winter visitor to the south-west,
northern Hejaz and Central Arabia where up to 1000 birds have been recorded in
a small area. They breed from the Black Sea eastwards across central Asia to
Mongolia and migrate to winter south to southern Africa and southern Asia. They
pass through the Middle East in large numbers on migration. The juvenile birds
shown below have wide even width whitish bands on the trailing edges and centre
of the underwings and on the tail tip. They also have a uniformly coloured body
and wing-coverts and whitish under-tail coverts. Whitish tips to the greater
upperwing coverts and secondaries form bands across, and trailing edges to, the
upperwings. They also have whitish uppertail coverts. The adult seen had dark
brown underwings with blackish carpal patches with wide dark terminal bands on
the flight feathers. They do not have the whitish underwing bands of younger
birds. Head, body and under-tail coverts are uniform dark brown.

Baluch Ground Gecko – Jebal Lawz
Whilst birding Jebal Lawz I found a small
and well camoflagued gecko on a rock at the end of a wadi. It was a Baluch
Ground Gecko Bunopus tuberculatus, a small, ground-dwelling gecko with
rather short, straight toes, a long tail, and conspicuous tubercles on the back
and flanks. The body is generally tan coloured, giving good camouflage against
its sandy habitat, and the tail is barred. As this gecko was living in a
mountainous landscape with dark rocks its ground colour was dark to match its
surroundings. As in other geckos, the eyelids are fused together, forming a
transparent covering to the eye, however, unlike many other geckos, it lacks
expanded toe pads, and is therefore unable to climb vertical surfaces. As its
common name suggests, it lives on the ground, digging burrows in the sand and
also hiding under surface debris. It is likely to be active at night, feeding
on a variety of insects, spiders and other small invertebrates but little is
known about it lifestyle. They have been reported as abundant and widespread in
vegetated sandy plains and in coastal habitats and can also be found in rocky
deserts and near farms, but are not seen in homes. They are found in the Middle
East, Arabian Peninsula and southwest Asia, from Israel, Jordan and Syria,
south into Saudi Arabia, United Arab Emirates and Oman, north to Turkmenistan
and east to Pakistan.

Looking for Chukar Partridge – Jebal Lawz
On 7 October Phil Roberts and I went to
Jebal Lawz, about 200 kilometres outside Tabuk, to look for Chukar Partridge.
We git there before first light and waiting to try to hear any birds calling.
The site is very remote and as a result is very quiet so hearing calling birds
should have been easy. In reality it was very difficult, made more so by the closed
and locked gate across the road preventing access to the top of the mountain
where birds had been seen before. We did eventually hear birds calling lower
down the road, but they were high up on a rocky mountain. I eventually saw two
birds calling from this high cliff face but the distance from the birds was
huge and the views poor. We stayed around for almost ten hours trying to hear
or see the birds again but without luck. Bird life was very limited in the area
and we only saw a few species including White-crowned Wheatear, Montagu’s
Harrier, Common Kestrel, Rock Dove, Desert Lark, Tristram’s Starling, Lesser
Grey Shrike, Pale Crag Martin, Scrub Warbler and Sinai Rosefinch.
