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.
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). 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.
