The birds we saw in Bhitarkanika

We were in Bhitarkanika National Park on 19 and 20 March. Everyone said that it was pretty late in the season and our sightings would be minimal. It was true that most of the winter migrants had left. Still the area is so rich in bird life that in three outings in the small area between Khola and Dangamal villages we saw eighty two species. Eighty one of them are listed here. The one I haven’t yet been able to identify is the slate and red bird in the photo below.

Contrary to the advise of some experienced birdwatchers, I’d expected this. My confidence was based on the comprehensive checklist published a decade ago which was a result of G.V. Gopi’s thesis work. This work listed a very large number of endemic species. Gopi put me in touch with the people whom he met during his field work, and that helped us enormously.

We had several lifers (marked in bold) and saw a few of the species which are globally threatened (marked with a star). Some of the birds I have written about in other posts; they are linked. Interestingly, every species we saw is included in Gopi’s checklist!

The list leaves out birds which we heard but did not see. These include not only the ubiquitous Indian Koel and the Common Hawk-Cuckoo (more widely known as the Brain Fever bird, due to its call), but also a couple of owls and a nightjar.

Bhitarkanika has several avian habitats. The area that we visited (coloured red in the map here) is reputed to be best for kingfishers and the pitta. Closer to the sea one should see the gulls and terns which we missed completely. There are also multiple viewing season. The time we visited is the leanest. Soon after the end of the monsoon one should be able to see herons nesting. The winter months will bring in the migrants, so loved by bird watchers in India. All this is in addition to the views of saltwater crocodiles, sea turtles and monitor lizards which this place is famous for.

I end this post with a mention of the most unlikely sight we saw: a monitor lizard being harried by a flock of Green Bee-eaters. The monitor lizard was probably interrupted in its search for eggs in the nests which the Bee-eaters build on the ground. These birds do not usually flock. They came together to harry the lizard, and successfully drove it away. I was so taken up by the events that I forgot I had a camera. You see wonderful things when you are in a forest.

The mangrove pitta

We were very lucky with our sighting of the Mangrove Pitta. As soon as our boat docked at the jetty in Dangamal, Amar, the boatman, jumped off the boat and asked us to hurry. Bijaya had called him to say that two Pittas had been sighted very close to the jetty. We hurried after Amar and saw Bijaya with a couple of people with the cameras and large lenses typical of wildlife photographers. One of them pointed out the bird. It was sitting in a bush, facing us, as you see in the featured photo.

It turned, hopped down to the ground, and offered many different views to the camera. You can see examples of these views in the rest of this post. The two photographers, Bijaya, Amar, The Family and I watched the bird foraging on the floor of the jungle. Several large groups of crocodile watchers passed by. Some stopped to examine us, and left when they found nothing of interest to them.

The origin of the colourful plumage of the Pitta has been a matter for speculation for long. It builds an open nest on the ground. Darwin and Wallace sparred for many years over the selective reasoning behind coloured birds with open ground nests. The argument was about the visibility of these nests to predators. Today we understand that their argument was important but premature, because the vision of birds and their major predators are not like human vision. Human eyes became red sensitive fairly late in evolution. Avian vision switched to ultraviolet sensitivity in many independent events (but not in the Pittas).

The Mangrove Pitta is called the Queen of Bhitarkanika on tourism posters. Humans seem to find its brilliant colours very attractive. It is the species on the cover of Grimmett, Inskipp and Inskipp’s field guide. Do Pittas also see the brilliant plumage that we are attracted by? I have seen no argument or study that clinches the issue one way or the other. However, it seems to me reasonable to assume that if the plumage was not under selective pressure in some way, it would change more easily over time, and one would be able to see races of Pittas with different colours. On the contrary, many species of Pittas have similar colouration.

We didn’t see a Pitta again, although we heard their distinctive call several times. Inside the forest it was hard to imagine that these lovely birds are on the decline. IUCN classes this as near-threatened due to habitat loss. Bhitarkanika National Park, with its protected mangrove forest, plays an important role in the conservation of this species.
