Chambal Diary: 6. River Lapwing

Previously aptly named the "Spur-winged Plover", the River Lapwing is a striking species with real spurs on its wings (see above) used during duels with fellow River Lapwings. These distinct more-or-less black-and-white birds share the riverside at Chambal with two other resident lapwing species - the Red- and Yellow-wattled Lapwings.

River Lapwings, as their name suggests, are found primarily along rivers. They find their food - insects, and other creepy-crawlies - in the sand and on vegetation along the rivers.

This species is adapted very well to river systems. They lay and incubate their eggs in a shallow scoop in the sand on river-banks and islands, much like their neighbours the terns and skimmers. Above, a lapwing incubates eggs beside a sleeping Comb Duck.

They are watchful parents. Here, one adult watches cautiously after ensuring that its chicks are well hidden among the scattered rocks on the island.

3-4 eggs are laid in the simple scoop - above a lapwing adjusts the eggs in the nest. Eggs are cryptically coloured: if the incubating bird were to walk away, it is exceedingly difficult to spot them on the sand.

Chambal diary: 5. Little Tern

The Little Tern is the smallest of the resident terns in the Chambal - tiny compared to the much larger skimmers and river terns. Instead of a neat full black cap, they have a white forehead, and a streak of black serving as eye-patches. Their legs are also much less colourful compared to their fellow terns and skimmers.

In this entry, I describe the nesting behaviour of this species of terns. Most of this behaviour is common with the other terns and the skimmer. This blog entry gives a snapshot into the part-ritual and part-politics that is an inherent part of the terns' lives.

The first thing to do for the males is to find a female who does not chase them away. A gift of a fish is mandatory to beginning the courtship ritual. Birds paired initially like this spend a long time - sometimes hours - standing in the position showed above calling to each other. The male ensures that the female does not snatch the fish away, but keeps it as tantalising bait until the female is ready to mate.

Competition for mates is common! Here, a male with a much larger fish tries to break up the courtship, but the male and the female bird that have bonded scare away the interloper. Clearly, size of the bait-fish is not everything!

After much posturing and courtship, the female finally allows the male to mate with her, and the male relinquishes the fish.

Mating itself lasts a very short time.

It appears to be the males' job to choose the spot where the female will lay their eggs. It is also his job to create the depression in the sand that will serve as the nest. The bird uses its belly, wriggles around in a circle until a depression is formed. The female watches over the whole exercise carefully.

Nests are located some distance from each other, and pairs are fiercely protective. There is a lot of jousting for space - both on the sand and in the air. Observing birds that nest in riverine islands is very rewarding. There is seldom a boring moment. Obsevers need to be very careful not to disturb the birds. It is less important to get full-frame photographs, for example, than it is to ensure that the birds are not disturbed.

Islands in the Chambal are exceedingly important for populations of a range of species, and here is to wishing that it continues to be do!

Chambal diary: 4. Indian River Tern

Gracefully proportioned with long wings, a fish-shaped tail, bright legs and yellow bill, the Indian River Tern is a sight for sore eyes.

It resembles the Black-bellied Tern, but is larger with a conspicuous white belly that allows easy differentiation of the two species. The habits of the River Tern are very similar to that of the other terns in the Chambal and the Indian Skimmer - it is also evolved for a life in clean rivers with plenty of fish and islands to breed on.

Human use of the river does not appear to affect the tern population in the Chambal suggesting that the islands are undisturbed during the breeding season, and that the fish populations are adequate.

Chambal diary: 2. Black-bellied Tern

Terns and Gulls are closely related and are usually associated with coastal areas. Indian inland rivers have breeding populations of a few species of terns that are specialized to reside and live off these rivers. The Black-bellied Tern is one such species. Good numbers of this species are found in the Chambal suggesting that conditions for breeding and feeding (mostly fish!) are currently good.

These birds breed in early summer on islands formed due to the reduction of the water levels. Dams, increased agriculture, and excessive accumulation of sand in the rivers can limit the formation of islands leading to reduction of breeding activity of birds like the Black-belled Terns. But enough lecturing - here are a couple more photos of this beautiful bird.

Two Black-bellied Terns mate on an island. Eggs will be laid on a small scrape on the sand, and both parents take turns to incubate eggs and to raise the chicks.

Black-bellied Terns are aggressive parents. Here one bird attacks a much larger egret - successfully - which strayed a little too close to the nest.

Its clean-up time!

Preen, dip, bathe, and scratch! These are the various ways in which birdies take good care of their precious feathers. Here are a few examples taken during clean-up time!

Preening is so very time-consuming! Here an Indian Skimmer (top) uses its unusual, spectacular beak to comb through feathers, and a Silverbill is busy at it while also showing off the preen gland (just above the tail) from where birds get an "oil" to keep their feathers ship-shape!


A bath can be a serene experience, like the Shikra in the water. Else it can be boisterous with water flying everwhere: for some Comb Ducks, one duck's bathwater is another's drink, apparently!

And finally, the soothing scratch! Here a Silverbill, a Black-necked Stork juvenile, and a Sarus Crane find out the real meaning of the phrase "for every itch, there is a scratch"!

Everybody loves a good sun

The Gangetic flood plains can get pretty cold in the winter, and in the early mornings of any season. Sunning is therefore a commonly noticed activity in the myriad life forms here - nothing quite like some temperature to put life back into the frozen bones. Here are a few life-forms doing their thing in the sun.

From top: A Baron butterfly warms up atop a garden plant; the Kachuga turtle suns atop a Gharial that is a fish-eater (something that the turtle obviously knows); a Green Bee-eater and a Greater Coucal open up their feathers to let the sun warm up the darker feathers on their backs.

Black-necked Stork allopreening

Remember "allopreening"? One bird preens the other as opposed to itself. See the Munia blog entry for an example. This behaviour has been studied by ornithologists quite a bit and general consensus is that it serves to reinforce bonding and is therefore commonly seen during courtship. Some groups of birds allopreen more than others - Black-necked Storks are not among those that are known to indulge in this behaviour. The photo above shows 4-5 month old Black-necked Stork chicks allopreening. In nearly 8 years of observing this species, this is the first time I saw this behaviour. Chicks in the nest are terribly aggressive to each other as they fight for parents' attention and compete for food. Wonder why they need to indulge in this behaviour after fledging from the nest.

Lily Trotters

Two species of birds in Uttar Pradesh are famous lily-trotters - literally! The Jacanas (pronounced "Ya-sah-na") have incredibly long toes that spreads out their weight allowing them to walk even on floating leaves. As if this were not fascinating enough, both are really easy on the eye! The top two photos are the Bronze-winged Jacana - very widespread even using heavily disturbed wetlands close to habitation. The bottom-most photo is of the elegant Pheasant-tailed Jacana which is much rarer and seems to shy from human disturbance. (Photographs date: May 21, 2009)

MmmmmMunias

Silverbills are a common species of Munias in Uttar Pradesh. They commonly engage in allopreening, meaning a bird preening another (as opposed to itself). And - as you can see - the preenee is better off than the preener. If one is not doing the trick, then maybe two will! (Photographs taken in Lucknow district, dated Nov 27, 2008)

Fiesty Lapwings

Red-wattled Lapwings are fiesty parents - no other word for it! I watched them use two principal devices to protect nests and chicks from potential predators: "Please-eat-me" and "dive-bombing". Adult lapwings with a brood of newly hatched chicks went into conniptions as a female, very mangy Jackal trotted out into the field they were in. The adults - quite amazingly - sat down in front of the Jackal taking to flight only when the Jackal almost caught them. I watched this pair in Rae Bareli (top photo) successfully lead the Jackal away with this please-eat-me technique. Another parent lapwing literally dive-bombed four Sarus Cranes each roughly 10-times its size when they came too close to a nest that was being incubated. For some reason, the chicks of the year recieved most of the violence (bottom photo) with feathers flying when contact was made. This happened in Etawah.

A blur of Weaver birds

Ok - I lied when I said that entries will revolve around ONE picture! A "murder" of crows, a "skein" of geese, and I propose a "blur" of Black-breasted Weaver Birds! These weaver birds are less famous than their close cousin Baya Weaver, which is the more commonly discussed species. The Black-breasted Weavers in Uttar Pradesh congregate in very impressive flocks in summer following the growing-up of the young birds of the year. In Jaunpur I "met" one such flock - easily 2000 strong - by being literally blocked by them as they crossed over the road. Farmers tilling the soil had little effect on the flock that was on a feeding frenzy. They are mostly seed-eaters, but it was impossible not to think "Hitchcock" when the flock took off at one point and flew at me! I suspect that the reedbeds formed along the increasing irrigation canal network is helping this species. (Photographs date: Apr 29, 2009)

Parakeet pollinating the Flame-of-the-forest

Butea monosperma or the Flame-of-the-forest is difficult to miss in early summer - bright clusters of flowers cover the canopy giving the tree its common name. The flowers are visited by a variety of insects, birds and some mammals. Here, a Rose-ringed Parakeet (a common resident species) digs into the keel-shaped lower petals of the flower to lick up the nectar. But the parakeet needs to work for the reward - the stamen pops out and smacks pollen on the forehead of the bird. As the bird visits different flowers and trees, it pollinates the flowers. A surprisingly large number of Butea trees still persist in the state - this photograph is from Farrukhabad district. Since the landscape is flat and largely agricultural, flowering trees stand out like beacons, and the floor below them gets carpeted with falling petals. A dash of orange (bottom photo) lighting up the usual earth colours! (Photographs date: Apr 4, 2009)

Sarus and Nilgai

Two species that are revered by farmers in Uttar Pradesh are the Nilgai (literal translation: "Blue Cow") and the Sarus Crane. Hunting of the Nilgai is strictly disallowed locally owing to the reference of a cow in its name. Currently, despite it being possibly the biggest crop pest, excellent populations of the large antelope proliferate all over Uttar Pradesh. The Sarus Crane is venerated for its life-long pair bond. Here , a Nilgai cow, her calf, a Sarus adult (right extreme) and a 7-8 month-old chick stare at me, disturbed from their feeding in a dried wetland in Barabanki district.
