Gold and feathers

Sunset on Bhigwan’s lake was a quiet time. Fishermen and farmers were on the way home from work. Herdsmen had brought their cattle to water for a last time in the day. Distant sounds of traffic had quietened. We’d heard calls of birds all day. That was completely gone as the light turned to gold. This was a good time for bird photography on the water. An Indian pond heron (Ardeola grayii) stopped looking for fish as soon as I’d clicked the featured photo and stalked to the hollow of the trunk and laid its head on its shoulder, preparing to sleep.

We’d been on open water most of the afternoon. Now, as we drifted close to the shore, I started noticing a completely different set of birds. There was a common redshank (Tringa totanus), its mottled and streaky feathers quite distinctive. I didn’t want the Black-winged stilt (Himantopus himantopus) in the photo, but the boat was drifting slowly and there was no quick way of getting it out of the way, except by changing focus.

There were reeds near the shore. I’d seen Garganeys (Spatula querquedula) all day, dabbling in the open waters. The white streaks on the head are quite distinctive. But none had come close enough for a photo. I took one now through the reeds. Behind it were Grey-headed swamphen (Porphyrio poliocephalus, formerly known as the Indian subspecies of Purple swamphens). I would get photos of them later.

At this time of the day, the colour of the water depends very strongly on which direction you look at. As I turned my gaze westwards I saw a Grey heron (Ardea cinerea) seated atop a mooring post sunk into the water. Behind it you can see one of the small villages dotted along the edge of the lake.

And finally, looking due west, on a sea of gold, a Brown-headed gull (Chroicocephalus brunnicephalus) had stopped its incessant daily flights, patrolling the water to keep it free of fish. Now it rested gently in the shallows. Later it would paddle closer to the shore and go to sleep on a sandbank. It was time for us to turn back too.

Many years ago when The Family wanted to start birding, we discovered that the ship-breaking yard in Sewri was a place where we could watch water birds. We went there every weekend for several months and became familiar with the common sandpiper (Actitis hypoleucos). Because of its name, I thought it wasn’t of much interest. Later I realized that the name merely refers to how easy it is to spot. And only now I realize that it is a very special species. But before I tell you why, let me just say that when you start watching birds you accumulate many photos of the more common ones, and eventually you begin to see their special beauty. I’m very fond of the featured photo of the common sandpiper which I took in a patch of waste water runoff behind Chhapar village in Rajasthan. I’m equally happy with the photo below of the common redshank (Tringa totanus), another sandpiper, taken in the same place. The redshank’s piping call tells you immediately why the family is called sandpiper. These beautiful waders can be seen across Africa, Asia, Europe, and also in parts of Australia.

Across the American continents one sees the spotted sandpiper (Actitis macularius), very closely related to the common sandpiper. So closely related that there is still gene flow between these two species; hybrid lineages have been spotted now and then. It seems that the species split very recently in geological time. Usually when we look at two different species, say a tiger and a leopard, they are not able to produce viable hybrids. However, when you trace them back to their common ancestral population, the distinction becomes less clear. There is a point at which the ancestors of the leopards and of the tigers could not be distinguished at all. A little later they would have been distinct, but still able to interbreed. Only with the passing of time have they come to be as distinct as they are today. The two species of Actitis remind us that the split between species occurs gradually. It amazes me to see this creative act of evolution frozen in time.
