A leucistic lapwing


Albinism - reduction in the melanin content (black colouration) causing whiteness - is a well-known condition in many animals. However, leucism - a reduction in all types of pigments, not just melanin - is probably more widespread and often confused to be albinism. Here, a Red-wattled lapwing, normally textured brown-grey on the wings (see previous post), displays leucism. The black on the neck and face, and on the flight feathers, are normal - this is not a condition of albinism for sure!

Of Owlets and Owlings

The young of an owl is an owling, while the owlets are a group of small owls. Uttar Pradesh's non-forested areas still retain several species of owls and owlets who appear to breed quite nicely as evidenced by the regular sightings of owlings. Here are two species that I was able to photograph.


Jungle Owlets may not be very appropriately named since they occur in a wide variety of habitats, many outside what may be considered a "jungle". This fellow was calling away on a Eucalyptus tree in the middle of a wheat-and-vegetable landscape.


The Spotted Owlet is perhaps India's most common and widespread owlet. The adult (top) is coming to terms with the early-morning lighting in the canopy of a Neem tree - the pupils of each eye are dilated differently. The owling of the Spotted Owlet (above) appears obviously teenager-ish, and is ready to begin hunting on its own at a few months of age. This particular one, however, was still depending on its parents to do the work.

Body language

Cranes have among the largest non-vocal communication repertoires in the animal kingdom. Body language is exceedingly important. Here are a few Sarusy gestures that other cranes would know the meaning of instantly.

Wing half-open, an exaggerated walk with legs raised higher than usual, this crane walks up very meaningfully to another Sarus that had landed uncomfortably close to an active nest. The interloper got the message rather quickly!

Crane employ a large number of threat postures increasingly aggressive in their meaning. This female (right extreme) gives a classic ruffle-threat combined with a bow to the pair adjacent to her territory while her partner engages them at closer quarters.

This rare bow-threat is carried out with elan and grace successfully dissuading a pair flying overhead from landing in this crane's territory.

Cranes'
large body size and incredible physical prowess poses a great risk of physical injury should they need to joust physically each time a disagreement occurs. Non-vocal postures with specific meaning, like the three above, are a safer alternative for all concerned.

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!

(A
ll photos were taken between Aug 2008 and Feb 2009 in the Uttar Pradesh portion of the National Chambal Sanctuary. 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!)

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"!

Cropland canids 2: The Indian Fox



The second-most common wild canid in Uttar Pradesh's (UP) croplands is the lovely Indian Fox, the commonest being the Jackal. My friend Abi Tamim who has studied foxes in south India tells me that they prefer grasslands and suchlike habitat there, though they do occur in small numbers in croplands. My sightings of foxes in UP have been very few to make any assessment of the population except that they appears to be widespread.

Unfortunate
ly the Indian Fox faces a number of problems in UP - dogs chase them down, crows attack individuals that are foraging in areas without vegetation cover (middle photo), roadkilled foxes are unfortunately commonly encountered on most well-maintained roads (bottom photo). Despite all this, successful breeding appears to be widespread evidenced by the pups-of-the-year (top photo) Hardly the area you would think ideal for a "carnivore" - but there you are!

This
is another lovely animal worthy of study in UP's crop-infested areas - how do they survive in this far-from-being-wild place? Fox sightings have been a real bonus and well worth getting up really early to get to transect points before dawn! All these photos have been taken at or before dawn.

Thanks are due to Abi for recognizing the pup-of-the-year (overa
ll gangly appearance; black on tail not as developed as in adults) and for various discussions on this amazing species he has studied for several years.

Cropland canids 1: The Jackal



Two canids are commonly seen in Uttar Pradesh's croplands - the Jackal and the Fox - and the third, the Wolf, is rather rare. Here, the Jackal is captured in a common crop - wheat (top and middle photo), and in the not-so-common amaranth. Jackals in Uttar Pradesh are run down by dogs all the time - one ran into the side of my jeep when it was being chased by village dogs, picked itself up, and disappeared into the wheat. Roadkills due to traffic are common on roads - I will spare you gory pictures of one here, and show you one later of the Indian Fox.

The Jackal appears to be doing quite alright in the cropped areas of UP - how this can be given the growing number of dogs, the lack of natural habitat, and apparent low amount of food is a mystery worth exploring.

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.

Scavengers nouveau



Dead cattle in India are skinned and left out for vultures to pick clean - eating cow meat is strictly forbidden in the country. The large resident vultures in India are all but gone - victims apparently to a veterinary drug that remained in these cattle carcasses. Crows and dogs have taken over in their stead, alongside a small-sized vulture - the Scavenger or Egyptian Vulture (middle photo). Villagers admit that the dog population has increased significantly since the disappearance of the larger vultures, but no one has paid attention to the crows. Both are predators as well - crows are very efficient nest predators and packs of dogs take down anything they can including Sarus Cranes and Nilgais. The Egyptian Vultures is widespread with good breeding populations in Uttar Pradesh and there is no information how its population here is doing relative to years with good vulture populations. While crows and dogs also scavenged before the larger vultures declined, they had access to much lesser amounts of food due to the aggressive habits of the vultures that dissuaded other smaller scavengers from accessing too much meat.

Surely, it should be a concern that continued disposal of cattle carcasses may be affecting entire communities of birds and other wildlife on the farmstead!

Myna hairdo

Mynas are neat birds – with lots of panache, attitude, and smarts. Not to mention hairdo!! This is a brief introduction to some of the styles you can see in the Myna world. The Pied Starling above has the touch-o'-white look; just a dash of old age on the side-burns.

This Common Myna (above) sports the just-been-shocked look.
Nothing like the wavy, wind-swept Harley look – preferred by the Brahminy Starling!
The Punk-and-Judy double-do sets these Bank Mynas apart; for couples only.
The mop-and-dandruff look – errrrrr….
And to end with this intricate centre-parted, backward-brushed, well-oiled, south-Indian, I-am-a-good-Myna look!

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)

High-tech tilling


The bond between machine and man takes on novel shades in Uttar Pradesh. Young and old alike participate in weighing down a plank of wood dragged by a tractor to cover up soil after seeds have been broadcasted by hand in a field. Apparently injuries are very few. (Photograph date: Nov 20, 2008)
