Not a fussy eater

I like this guy, but I can’t say I like his eating habits. This White-breasted Kingfisher (Halcyon smyrnensis) sat on a branch hanging over the edge of a swamp in Bharatpur and kept darting down to the water and coming back to its perch. This is one of the species of Kingfishers which does not live by fish. It mostly eats insects, although it isn’t finicky. About one sixth of its diet consists of vertebrates, perhaps occasionally other birds.

I was curious about what it was eating now, and I had a new camera. It wasn’t hard to get a series of close ups. What was that it had picked up? Was it a water strider? The legs were long, but the body was even longer. Probably not a water strider then. Also, it hadn’t darted down to the surface, but had snatched up the morsel of food from the air. Could it be some kind of an Orthoptera, a grasshopper or cricket? The body was rather thin. Its wings, if it had any, were folded. I wished I’d seen its head and antennae.

A bunch of field biologists found that H. smyrnensis spends about half of the day scanning its surroundings for food, and only about a quarter of daylight hours actually feeding. It seemed to me that the time spent in feeding was less. This Kingfisher did not give me much of a chance to continue my differential diagnosis of its diet. The long-bodied insect was gone in a jiffy. Was the process of eating over? Apparently not. The tongue of a White-breasted Kingfisher is a marvelous organ, well-adapted to its diet, breaking down its hard shell slowly while it sits and scans the surroundings for the next morsel.

Free birds

Ruins and villages may be closer to nature than cities, but they are not exactly forests. The birds that you see in such places are ones which have adapted to profit from the disturbances that humans create. Around Mandu we saw several birds, but a bird watcher in a city will see most of them. The featured photo shows the green bee-eater (Merops orientalis), common across a huge swathe of sub-Saharan Africa and southern Asia: from Senegal in the west to Vietnam in the east. I love this colourful and commonly visible bird. I hadn’t realized earlier that it is appropriate for Independence Day; it has the colours of the flag.

The white-breasted kingfisher (Halcyon smyrnensis) is another common and widespread bird, being found across Asia, from Turkey to the Philippines. It has learned to supplement its diet by scraps of meat from kitchens, and is now commonly seen around human habitation near water. It allows a photographer to get reasonably close, so this shot against the sky is not among the best I have.

The red-wattled lapwing (Vanellus indicus) is not easily visible inside a city. But this large wader is common in wetlands anywhere in southern Asia, from Iraq to the Philipphines. I saw these large birds everywhere in Mandu, even in Jahaz Mahal. This photo was taken in the garden just outside the palace.

Although this is not a high-quality photo, I’m fond of it because I caught two different species in the same shot. The spotted dove (Streptopelia chinensis) is common is various terrains, including cities, across Asia. It has been introduced in Hawaii, California, Australia and New Zealand. The other bird is a coppersmith barbet (Psilopogon haemacephalus) was common in our garden till recently. It is a common Indian bird.

Like the rose-ringed parakeet, the Indian robin (Copsychus fulicatus) is another species which I notice around ruins. I watched this one as it hopped and flew along ruined walls in Mandu. Unlike the parakeet, it does not take to gardens inside cities. We were not really looking for birds, but were happy to have this added extra.

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.
