A very confusing bird

We crept up to the small pond which you can see behind the trees in the photo above. There were about twenty birds in the water, a mixture of species. I took a few photos while we were still far away, just in case the birds noticed us and flew away. But the trees shielded us from view, so we could get in reasonably close and get a good view.

One of the common water birds which I would have liked to see is the common Greenshank (Tringa nebularia). It winters in India, China, and southwards, all the way to Australia as well as South Africa. In summer it moves far north, to Scotland, Norway and Siberia to breed. It used to be common in the waters around Mumbai, Marsh sandpiper or common greenshank? Bhitarkanika national park but I’ve not seen it for some time. The pond had something like it, but our guide peremptorily said "Marsh sandpiper". I’d not seen this closely related bird, Tringa stagnatilis, before. The Family had no opinion. I took a record shot (alongside) and moved on.

The fun started after we opened our field guides much later. It turned out that the two birds can be easily confused. Grimmett, Inskipp and Inskipp told us that the Marsh Sandpiper is "smaller and daintier" with "proportionately longer legs". The bit about the legs is repeated in the Wikipedia article. Since the bird had not moved at all while we watched, we had no idea about the length of its legs. What about the range? The greenshank is definitely found in Bhitarkanika National Park, whereas the Marsh Sandpiper is "known to be occasional, scarce or erratic". Could we decide by the fact that it was the middle of March? No, since the northward migration does begin in March (at least in Africa) but apparently continues up till the middle of May.

The only possible resolution came from The Family, who noticed that the greenshank has a slightly upturned beak, whereas this one seems to have a completely straight one (hard to see in the photo). We found a good online field guide, which made us look harder at the photo: the pale streak along the eye and the bright white underparts, both of which are characteristic of the Marsh Sandpiper. So perhaps it is that after all, and we have just added some weight to its "scarce" sighting in this region.

What do you think?

Forgotten kings

And on the pedestal, these words appear:
My name is Ozymandias, King of Kings;
Look on my Works, ye Mighty, and despair!
Nothing beside remains. Round the decay
Of that colossal Wreck, boundless and bare
The lone and level sands stretch far away.

—Percy Bysshe Shelley

My Ozymandian moment came as we walked through the mangrove forests of Bhitarkanika. We passed a shallow swamp with dead trees standing in them. Then we crossed a field where a monitor lizard was being harried by green bee eaters. The huge lizard crawled into bushes. We skirted the bushes, and as I looked at the little rise, I saw an abandoned building. It wasn’t too old, but disused and fallen into ruin. Bijaya said it belonged to the Rajah.

Who was this? He had no explanation, but it seemed that it was the local zamindar. The system of zamindars was abolished by the state of Odisha in 1952, so my guess is that the structure is about a hundred years old or less. As I walked around it, I saw a lotus pond where two bronze-winged Jacanas walked on the lily pads pecking at the water delicately. An Indian pond-heron sat apart from them on another lily pad, seemingly withdrawn into its inner landscape. From the pond one could see little slits along the walls of the structure. It was clearly a blind where the zamindars of old could sit and decimate birds which came to the pond. Much research was needed to excavate the names of the family. In sixty years the Kanika family which owned this forest once is almost forgotten.

We skirted the pond and walked into the next clearing. A small plaster Nandi shows that this is a Shiva temple A simple temple in the Odisha style stood under a mango tree (featured photo). Amar tried to bring down a couple of mangos, and was fairly satisfied by the unripe green fruits he got. The temple was not much older than the blind; the two structures used the same kind of mortar. But whereas the hunting blind was like Ozymandias’ statue, the small temple was kept alive by the traditions of neighbouring villages. I walked around it to see a little mortar Nandi facing the niche where a diya burnt in front of a tended shiva-linga inside a little locked screen door.

We walked on past these little remnants of a history now forgotten. The forest was alive with birds, and our hour’s walk was over too soon.

Clades of Kingfishers

After reaching the Bhitarkanika National Park, we learnt that the brown-winged kingfisher is called the king of the forest. It was abundant. The flash of its orange and blue colouration easily visible, and often, in the green of the mangrove forest. This was one of the seven species of kingfishers we saw in a day.

So many species gave me some pause. How did they evolve? How are they connected? The current understanding of the evolution of kingfishers is that they probably radiated from southern Asia, speciating rapidly as they filled new niches in Australia and the Pacific islands. The Americas are likely to have been populated through two independent migrations from the Old World landmass. Studies are incomplete, and especially in the biogeographic ranges of Asia and India there is much that remains to be discovered.

There are three major clades of Kingfishers: Alcedininae (river kingfishers), Halcyoninae (tree kingfishers), and Cerylinae (water kingfishers). All three are present in Bhitarkanika national park. As far as we can tell today, the river kingfishers diverged from the base of the evolutionary tree. The branching between the other two clades came later. The small blue kingfisher (Alcedo atthis), the white-breasted kingfisher and the pied kingfisher, representatives of the three clades are widespread in India. Somehow I didn’t have a good photo of pied kingfishers before, and I managed to get a fairly good one on this trip (below).

Here are the seven species we saw, listed in the three clades. The name in italics is the genus to which the different species belong.

  • River kingfishers (Alcedininae):
    • Alcedo: Small blue kingfisher
  • Tree kingfishers (Halcyoninae):
    • Halcyon: White-breasted kingfisher, Brown-winged kingfisher, Stork-billed kingfisher, Black-capped kingfisher
    • Todiramphus: Collared kingfisher
  • Water kingfishers (Cerylinae):
    • Ceryle: Lesser pied kingfisher

We’d seen stork billed kingfishers during our trip to Andaman in December. They did not seem to be particularly common there. They seemed to be even more rare here. We saw one briefly sitting with a pair of brown-winged kingfishers. They have similar bright orange coloration, with long red beaks, and it takes a moment to realize that the stork billed does not have a brown wing. I did not get a photo here at all. The ruddy kingfisher is seldom spotted here. One of the cooks at the hotel we stayed in was very interested in birds, and kept asking us whether we’d seen this. He told us that he has never managed to spot it. This agrees with Gopi’s checklist, which states that it is a vagrant. We never saw one.

Collared kingfisher, Todiramphus chloris, in Bhitarkanika National Park, India

I’d first seen the collared kingfisher in Andaman. They are quite common here, and I managed to get a better photo than I’d got in December (above). Black capped kingfisher, Halcyon pileata, in Bhitarkanika national park, India It took me some time to spot the black-capped kingfisher. Our boatman, Amar, kept pointing them out to us, and I couldn’t see them at all for a while. Then I realized that they flit between the dipping branches of mangroves and the water. After that I caught sight of many. Eventually, the best photograph was of one which sat on a mooring pole for boats (alongside). The splash of lilac near the base of its tail is barely visible when it is perched, but is a beautiful sight when it flies.

Which part of Bhitarkanika is best for sighting of kingfishers? We found that the backwaters between the jetty in Khola village and Dangamal is a great place for these birds. We spotted all seven species in a single one hour boat ride between these points. You can also see them almost anywhere near the waters.

Crocodiles of Bhitarkanika

It had rained in the night and the air was distinctly cooler. When we set out on the boat in the morning we had our first sighting of a fully grown salt water crocodile: about 5 meters long. This is Bhitarkanika National Park’s flagship species. It had pulled itself out of the muddy water into the bank. Its colour merged perfectly with that of the mud around it; only the long shadow of the morning gave it away. As our boat drew near, I could see that its eyes were open and tracking us. When we drew too close for its comfort, it darted across the mud, into the water. A quick swirl of mud, and it had disappeared into the murky depths. The calm creek we were on suddenly seemed treacherous. We had no idea how many dangers lurked beneath us.

Through the day we saw adults basking in the sun, always alone. Each disappeared rapidly into the water if we approached too close. These two facts seemed to suggest that these crocodiles are highly territorial. Very likely, stretches of the river "belong" to one individual. This would also make them extremely wary of creatures larger than them: possibly dangerous rivals.

Yearling crocodile in Bhitarkanika, Odisha

The previous day had been sweltering warm, and we hadn’t seen any adults. However, the banks of the creek were full of immature crocodiles: from the 30 cm long yearlings to meter-long three-year olds. The youngest ones are the lightest in colour and easy to see against the mud on which they rested: as you can see in the photo above. I call them yearlings, but they are more likely to be about 8 months old, since the breeding season starts in about two months.

I doubted that the young could hold their own against the monsters which ruled the creek. What could these young eat? I had my answer the next day. A carcass of a cow had been lying by the river for a day, and I found three young crocodiles feeding on it. The boatman told me that a carcass like that could feed a very large number of yearlings. I guess that even the adult crocodiles eat more or less anything that they can find. We saw deer and monkeys by the creek, and only the youngest seemed to venture close to the water. Perhaps the crocodiles are opportunistic feeders on these unwary young.

The crocodile is a star attraction in the protected area of Bhitarkanika. However, its speed and size probably means that one has to be extremely careful around them. There are signs everywhere which even the usually unruly Indian tourists follow. I hope accidents are very rare, otherwise the good job of conservation which this forest area does will be in danger.

Crocodiles, herons and turtles

In a couple of weeks I have to fly to Odisha for work. I talked to The Family about taking the following weekend off. With a little juggling, it turned out that she can also travel that weekend. We’ve spent 40 days without seeing an animal wilder than a crow or a pigeon, so we decided to make this a quick wildlife trip.

A look at the map shows us that Odisha is full of national parks. There is a lot of choice in principle. Our main constraint is that this has to be a quick trip. The only airport in Odisha is in Bhubaneswar, and to save time we want to travel no more than three hours. This narrows our options to Chilka lake and Bhitarkanika National Park (highlighted in the map above).

We spent a day and a half in Chilka lake a few years ago, watching freshwater dolphins. We’ve also been thinking of going back there for a spot of winter bird watching. Mangalajodi has become the glam destination for birders, with articles being written about it in The Guardian and Livemint. The conversion of poachers into bird guides is certainly a very romantic story. Another reason why it is written about so much is that in winter even a novice can spot lots of birds. But this is late in the season, and the winter’s avian visitors would have begun to depart.

So we begin to think of Bhitarkanika National Park. This is a wetland protected under the Ramsar convention. The big two here are saltwater crocodiles and Olive Ridley sea turtles. These endangered turtles return to the nearby Gahiramatha beach every year to breed. The discovery and subsequent protection of this, the world’s largest breeding site for the turtles, is one of India’s success stories. A newspaper article tells us that they have already arrived this year. I can’t find any information about whether it is possible to see the nesting of these turtles.

Saltwater crocodiles are a constant tourist draw in Bhitarkanika, so there is an efficient process to visit the places where they can be seen. A little reading assures me that we will be able to see them.

The Family asks about bird watching. I find a two-year old fluff piece on bird watching in Bhitarkanika. A little more searching brings up the definitive checklist of the birds of this wetland. In a two-year long survey, conducted a decade ago, two dedicated and talented naturalists, Gopi and Pandav, found 263 bird species in the area, of which 147 were residents. I learnt from this paper that the park hosts one of the largest heronries in the world. A heronry is a tree, a group of trees, an island, or an inaccessible area where herons breed year after year. During breeding season, which is about now, it is a spectacular sight.

We know nothing about local conditions, have no contact with local experts in Bhitarkanika National Park. We might be lucky and see lots of things, or we might not. But it seems like a place worth visiting.
