20 August. Lake Arzhan.
I had um'ed and arr'ed over visiting Lake Arzhan right up to the moment of going - the scant information I had (an I.B.A. notification) suggested that whilst good for wildfowl after the winter rains, it would most likely be a dry dustbowl at the time of my visit. Still, I reasoned, it was basically on my route and the surrounding open woodlands, on steep rocky slopes and dominated by Persian Oak, were said to hold good concentrations of Upcher's Warblers.
Just 40 km west of Shiraz, I arrived on site at the rather late hour of 10 a.m., a quick glance confirming my suspicion that the lake would be dry. I guessed I would stay here an hour or so ...I didn't, Lake Arzhan turned out to be one of the big surprises of my whole trip, 24 hours later I was still birding the area! It was a fantastic little oasis - from the clutter of roadside restaurants, food stalls and small shops catering or the busy Shiraz-Bushehr road, a permanent spring brings life to the otherwise parched area. Flowing through a coppiced woodland, a stream then flows out across the dry lake bed, curling to a final halt in a fairly extensive bed of phragmites, wet marsh and occasional open patch of water. Adjacent, with nomad camps and cattle wandering, the remainder of the vast lake bed is a dusty concoction of trampled turf, weed scrub and thicket. And there were birds everywhere!
Leaving my transport, expecting virtually no birds, I had wandered first into the woodland - a Spotted Flycatcher popped up, then another. 'Ooo birds', thought I. Then more birds, the woodland was heaving, undoubtedly a mix of migrants and residents, seeking shelter and seeking the cool waters of the stream. Before very many minutes, I had settled myself in amongst a flock. Spotted Flycatchers continued to hawk from low branches, but all around a right flurry of action, non-stop birds circulating in loose association - a Rufous Bush Robin low down, several Olivaceous Warblers, three Plain Leaf Warblers, a humble Blackbird and then, a swing of a long dark tail, an Upcher's Warbler, the only one I would see on this trip. From the shade of the trees into a sunny glade, the stream was a magnet to thirsty birds, another buzz of activity - Moorhens and a Water Rail in emergent vegetation, a right chatter and twitter coming from tall dead trees, the boughs positively alive with stacks of Goldfinches and, quite unexpected for me, at least 35 Desert Finches flitting in and out, real smart birds.
Out of the woodland margins, a touch of sunbathing, largely to dry out trousers after an inadvertent step near the stream, a nice marshy hollow promptly found. But what a glorious spot to sunbath - European Bee-eaters swooping, a Hoopoe quietly probing nearby grass, the Desert Finches now sharing thistleheads with the Goldfinches. Up high above, clouding in swirls above towering cliffs, an immense flock of Choughs, 200 strong and tumbling down to the lakebed, scattering to forage amongst the cattle dotted in the distance. Through the black masses, hurtling bullets, 15 Alpine Swifts soared out from the cliff tops, arcing out into blue skies. Plenty of birds to watch, all sides and overhead.
Butterflies numerous too - Silver-washed Fritillaries common, Clouded Yellows and Red Admirals reasonably so, plus quite a number less familiar - various blues and browns, plenty of a big Greyling type I have yet to pin a name. T'was now 35 C, but most pleasant, I decided to follow the stream out across the lake bed - a snake of water and reed, birds abundant all the way. Plenty of Yellow Wagtails, no shortage of Black-headed Buntings and at least 60 Corn Buntings, plus dwellers of the deep reed, one Great Reed Warbler, several European Reed Warblers and at least three Moustached Warblers, typically the latter very much creepers of the reed base. Rising Mallard and circling Marsh Harriers hinted of riches deeper in the marsh, but as afternoon turned to evening, out into the parched grasslands I chose to wander. A Northern Lapwing eyed me warily, surely this locality must attract a Sociable Plover or two on passage. Not his day however. Instead the glories went to Isabelline Wheatears, at least 25 scattered in my immediate environs, a Northern Wheatear thrown in for good measure. As dusk approached, Common Starlings came flocking in, 800 or so settling in the reeds, smaller numbers of Barn Swallows also present. Isabelline Shrike and Lesser Grey Shrike both occupied the remnants of an old fence, the sun was setting.
Night fell, under the coppiced trees I pitched my tent. A reward for my excellent day, I walked up to the roadside restaurants to treat myself to a meal, my first in Iran! A huge helping of rice, kebab and assorted sidelines, my stomach did not know what had hit it.
