This unique lowland area in the northwest of India lies between the southern edge of the Thar desert and the Arabian Sea. With each monsoon, floodwaters flowing south get backed up here, creating a vast lake often less than a metre deep on which local villagers go fishing. In the dry season it becomes the moonscape we were now traversing. Even in the driest months, the Rann has RAMSAR-listed perenial wetlands, a refuge for huge numbers of waterfowl. Also dotted amongst this remote vastness were isolated ‘islands’ of thornscrub, known as phets, and it was to one of these that we were being driven in the predawn.

Our dilapidated Land Rover – with no windshield or doors, atrophied suspension and a top of speed of 30kph – felt like one of NASA’s Apollo moon rover buggies. Micro-fine dust was being kicked up by our wheels, and settled over everything, eerily flowing almost like liquid.

Beside me, our local driver Mahboob, his head completely swaddled in a shawl against the night chill, reminded me of some desert alien from a Star Wars or Dune film. In the days he had driven us around the Rann, despite little language in common, we had grown to enjoy his quiet, good spirits and easy smile. How he navigated unerringly around this featureless region was an utter mystery.

But now my faith in his uncanny ability was faltering. When we had set off, the setting stars of Orion had hung over our bonnet as we headed west. During the past five minutes they had drifted slowly to our left side, and were now almost behind us. A few minutes later they were over my right shoulder. We were going in a huge circle.

I looked over at Sarah huddled in the back, a pulled a face. Mahboob looked aglance at me, smiled broadly and wiggled one hand in the air. Yep, we were lost.

During the previous few days, we had been based at the Desert Coursers Lodge at Zainabad on the edge of the Rann, and Mahboob had driven us out each morning and afternoon to likely recording locations.

At first sight, the barren Raan didn’t look like a promising place to be recording nature sounds. Even Sarah was finding the empty landscape a challenge to photograph. It had atmosphere, no doubt about that, but at first we were wondering whether we would get any worthwhile recordings at all.

On the first morning, our doubts were swept away. Mahboob rolled the old Landie to a halt at the edge of some low bushes, and indicated that we should walk on. Pushing through them, we found ourselves on the shoreline of a broad, expansive wetland. Before us, mirror-still waters were covered with the graceful pink and white forms of hundreds of Lesser Flamingos. It was such an unexpected scene in this barren landscape, that Sarah and I found ourselves in a state of childlike wonder. It was a sight we had never anticipated to see. Ducks, pelicans, stilts and cranes were also out on the waters, silently feeding in this surreal place.

Later that morning, we came across a small herd of Wild Ass, or Onager, Equus hemionus. Found only in the Rann, loose family groups of these rare animals subsist on the sparse grasslands. They have a habit of hanging their heads over each other’s neck, which is quite endearing.

That afternoon we identified a promising recording location. Exploring one of the thornscrub phets, we found it to be a haven for small birds; babblers, prinias, silverbills, bee-eaters, coucals, doves and bulbuls were prolific.

Just on sunset, groups of Grey Francolins, Francolinus pondicerianus, began calling, their cackling calls echoing across the landscape, revealing them to be a much more numerous than sightings alone suggested.

So for the next few mornings we recorded among the thornscrub, and encountered some of their more secretive inhabitants. We were surprised to find Nilgai and other deer in such desolate surroundings.

Stone Curlews and Short-eared Owls were seen at dusk, and occasionally we’d come across small groups of Common Cranes, Grus grus shyly feeding among the scrub or flying overhead in stately formation on lazy wingbeats.

The Rann was slowly revealing its wonders to us.

With the first pale light of dawn arriving in the east, we were still lost on the Rann. Just as I was beginning to think we would miss a recording of the dawn chorus, a line of short grass appeared in the headlights, and beyond that ‘beachline’, a wall of low thornscrub. By good fortune, we’d found a phet, although probably not the one we’d intended. Relieved, I bundled out with my recording gear, and made my way into the scrub.

That last morning yielded a very good recording, with flocks of tiny Silverbills, Lonchura malabarica, winging overhead, and a diversity of delicate birdsong drifting over the landscape. The ringing of cowbells and occasional yell of a cattle herder in the distance added a human touch to the ambience.

Returning, something caught my eye on the ground. A pattern in the now-dried mud had been made by a large animal (deer or cow maybe) urinating. It was utterly unique and distinctive. But the extraordinary thing was that I had noticed this exact mark yesterday. Looking around, I recognised the patterns of scrub – it was precisely the same location that I had been on previous mornings. Mahboob’s navigational abilities were indeed redeemed!

Back at the Landie, Sarah shared some atmospheric dawn landscapes she’d photographed, and we prepared to set off. Mahboob fired up the engine but it promptly died. He leaned down and held up the accelerator peddle; sheared off completely. Despite everything, there was something amusing about our predicament. Mahboob wobbled his head and ‘tut, tutted’ to himself. Whilst not being alarmed, we were curious how we were going to get ourselves out of this one.

Mahboob rummaged around under the seat and emerged with… a used fan belt. Great, very useful… More rummaging, this time under the bonnet. A few minutes later, he’d tied the fan belt to the throttle cable and fed it back into the cab through a gap in the chasis under the steering wheel. He turned over the engine again, pulling on the fan belt to rev the motor happily. Big grins all round – the man was truly amazing!

Our album ‘The Great Rann’ presents nature sounds from this unique part of the world. On this 3 minute sample from the album, you can hear excerpts from each track.

Track 1 was made in the darkness of pre-dawn on the edge of one of the Rann’s wetlands. Waterfowl including stilts, ducks, teal, cranes and flamingos are heard calling quietly in the darkness. From the wetlands, we move on to the thornscrub phets, beginning with a dawn chorus of francolins, and progressing through that lovely morning of drifting birdsong. Towards the end a group of Common Cranes call as they fly leisurely overhead (track 3). Finally, on track 4 you will hear the dusk calls of francolins merge into a cricket chorus of nightfall.
