Chambal diary: 3. Indian Skimmer

Skimmers are unique in having a longer lower mandible relative to the upper - a bird with a permanent pout if you will. They use this amazing "device" to literally skim the water surface (photo below) snapping the beak shut when they come into contact with a fish. The Indian Skimmer is therefore very easy to identify being the only skimmer species in India. They, like the Gharial, are exclusive fish-eaters.

One of the largest known populations of the Indian Skimmer is located in the National Chambal Sanctuary. They, like the other terns, use the islands to nest in. This charismatic, attractive species is a superb indicator of undisturbed rivers. Here are some Skimmer photos showcasing its habits.

Skimmers, fortunately, never have to go far to bathe!

Pair-bonding prior to mating and egg-laying is very important. Above, a male (larger bird on the left) gives the smaller female a gift of a fish before they set up their family for the year.

Both parents take turns to incubate eggs, and feed chicks. The two pictures above show a nest-change - one bird settles in on the eggs after feeding, and the other takes a break. The bird coming in wets its breast and belly feathers before restarting incubation duties to ensure that the summer heat does not bake the eggs. Small Pratincoles also incubate eggs of their own beside the skimmer's nest.

In the absence of directed persecution, Indian Skimmers appear to be able to persist in the presence of some human disturbance. The National Chambal Sanctuary is bounded by villages along its entire length whose people use the river in various ways. So far, this use does not seem to be affecting the skimmer population.

The Indian Skimmer and The Gharial - two species entirely reliant on unpolluted rivers with good fish populations and islands in the summer months to breed on.

Chambal diary: 1. The Gharial

The Chambal river is the border between Uttar Pradesh and Madhya Pradesh for a bit, and remains one of India's cleanest rivers. The National Chambal Sanctuary has succeeded in preserving very good populations of several truly bizarre yet incredible animals. The river is not strictly part of my PhD study area, but is very much part of the Sarus scape, and is one of my favourite locations in Uttar Pradesh. It therefore qualifies to be included in this blog! This small series of entries is a celebration of some of these denizens!

The Gharial is found only in south Asia. It is closely related to crocodiles, and has been around on Earth for a very long time.

It is an exclusive fish-eater - something that the turtles in the Chambal seem to know quite well!

The National Chambal Sanctuary in Uttar Pradesh has a great record of breeding Gharials - it is common to see young babies (top), and teens of all sizes (below) basking on the sands!

The crocodilian gets its name from the inverted pot-like mound on the end of the adult male's snout - a ghada in Hindi, if you will.

The Gharial has its set of problems even in the protected Chambal. I must underscore that these have diminished greatly thanks to an active forest department staff, and a force of dedicated conservationists and scientists. One of the more horrible things that used to happen a lot in the past was due to illegal fishing in the river. Gharials used to get stuck in fishing nets trying to get at the captured fish. Fisherfolk, in their hurry to escape, and to save the nets and fish, slashed at the captured Gharial with knives sometimes cutting off part of the snout.

Some of these Gharials lived (above), though not for long. They are probably not able to catch fish with their reduced snouts!

Many Gharials, however, are lucky to escape with part of the net sticking out of their snouts like forgotten floss (above).

Fishing has reduced greatly as a threat, and Gharials now seem to be able to live to ripe old ages (notwithstanding catastrophic and unpredictable events like a recent die-off - which has completely stopped, thankfully)!

I owe a great debt to the Uttar Pradelsh forest department for inviting me several times to participate in their Gharial and bird censuses in the National Chambal Sanctuary. Despite exceedingly limited resources, staff are very active to ensure that illegal fishing is reduced, and wildlife is as undisturbed as possible. A great resounding ovation to these folk, and to all the scientists and conservationists working to conserve these totally fab animals!

For those interested in Gharial conservation and ecology, be sure to check out this fabulous website dedicated to these amazing animals: http://www.gharials.com. Two fabulous films have been made on the Gharials - one classic is The Ganges Gharial by the Bedi Brothers, and a more recent Crocodile Blues by Icon Films: both must-sees for Gharial and nature buffs!)

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.
