The national bird of a country is a designated representative of that country’s fauna. It is chosen on the basis of the unique qualities that the bird may symbolize. It should uphold certain core qualities or values of the nation it belongs to. The national bird should be a prominent feature in the cultural history of the country. Another point in favor of being chosen as the national bird is the beauty that it embodies. The indigenous nature of the bird is another point while it is being considered as the national bird. Being designated as a national symbol affords the bird a special status with increased awareness and dedicated conservation efforts.

National bird of India is the Indian Peafowl commonly termed as a Peacock. Vividly colorful and exuding oodles of grace, the Indian Peafowl commands a lot of attention. The peacock and its colors are synonymous with Indian identity. It is indigenous to India and Sri Lanka, but now features in countries all over the world. Peacocks are sometimes domesticated and kept in the garden for aesthetic purposes.

Distribution

Indian peafowls were initially indigenous to the Indian Subcontinent – currently India, Nepal, Bhutan, Pakistan, Bangladesh, Myanmar and Sri Lanka. It has been introduced to other parts of the world over the ages including Europe and America. Semi-wild populations occur in Australia, New Zealand and even in the Bahamas. 

Habitat

They are found in low altitude areas, generally below 1800 meters from the sea-level. In the wild, they inhabit a wide range of habitats ranging from semi-dry grasslands to moist deciduous forests.They prefer to live near water-bodies. They also live around areas of human habitation, near farms, villages and often in urban areas. They forage and nest on the ground but roost on trees tops.

Physical Traits

The males of the species, also known as peacocks, present a strikingly beautiful appearance that is well-appreciated throughout the world. They can grow to a length of 195 to 225 cm from tip of the beak to the end of the train and weigh an average of 5 Kg. The peacock’s head, neck and breast are iridescent blue in color. They have patches of white around the eyes. They have a crest of upright feathers on top of the head which are short and tipped with blue feathers. The most notable feature in the peacock is the extravagantly beautiful tail, which is also known as the train. The train is fully developed only after 4 years of hatching. These 200 odd display feathers grow from the back of the bird and is part of enormously elongated upper tail coverts. The train feathers are modified so that they do not have the barbs that hold the feathers in place and are therefore associated loosely. The colors are a result of elaborate microstructures that produce a sort of optical phenomena. Each train feather ends in an oval cluster bearing an eyespot or ocellus that is extremely eye-catching. The back wings are greyish brown in color, and are short and dull.  The Indian Peacock’s thighs are buff colored and they have a spur on the leg above the hind.

The female peafowl or peahen lacks the flamboyant colors altogether. They predominantly have brownish grey coloring, and sometimes have a crest similar to the peacock but brown in color. They totally lack the elaborate train and have dark brown tail feathers. They have whitish face and throat, brown hind neck and back, a white belly and a metallic green upper breast. The Peahens grow upto a length of 0.95 m and weigh somewhere between 2.75 to 4 Kg. 

There is some color variation found in Indian Peafowl species. The black-shouldered variation results from a mutation resulting from genetic variation within the population. Mutation in the genes producing melanin, results in white peafowls that have starkly white feathers with cream and brownish markings.

Behavior

The Indian peafowls are best known for the beautifully elegant display of feathers the evolution of which is believed to be driven by sexual selection. The peacocks spread their train in the shape of a fan and quiver them during the courtship display. It is believed that the number of eyespots in a male’s courtship display determines his success in mating. Peafowls are omnivorous in their feeding habit and survive on insects, seeds, fruits and even small mammals. They forage on the ground in small groups which has a single male and 3-5 females. They roost as a group as well on the upper branches of a tall tree to escape predators. When agitated they will prefer to flee by running, rarely opting to take a flight. The males are surprisingly agile on foot despite the long train. 

The Indian peafowls do not have any specific breeding season and mating is generally dependent on rain. In south India, they mate during January to March, while in northern parts of the country they mate during late July to September. The males occupy small territories and females visit these territories assessing the suitability of the males for mating. Eligible males are surrounded by females who take turns to mate following repeated courtship display by the males. The call of the Indian peafowl is a loud, trumpet-like scream “kee-ow”. It commonly advertises the presence of the male during the breeding season, but also heard in the late afternoon and after dark, possibly as a warning against predators.

Life Cycle

The peacocks are polygamous in nature. The peahen lays around 4-6 eggs in the ground, preferably in a shallow hole and incubate these for 28-30 days. The chicks are reared by the mother for about 7-9 weeks by feeding food from the mother’s beak. The mother peahen then travels around with the chicks in tow and possibly teaches them to forage. The male and female chicks are indistinguishable initially. The males start to develop the distinctive plumage from two years of age and they mature at around four years. The average lifespan of the Indian peafowls in the wild is 15 years.

Threats and Conservation

Threats towards the Indian peafowl arise due to the demand for the beautiful feathers to be used for decorative purposes. They are hunted and killed by poachers for meat as well. They can be a nuisance when inhabiting near farms as they prefer to feed on crop grains. They can be hunted down for the reasons stated above although that is not a common practice. 

The Indian peafowl has been granted special conservation efforts owing to its status as the National Bird of India. Hunting of the national bird is illegal. Although the total number of Indian Peafowl is unknown, they are abundant enough to be labeled ‘Least Concern’ by the IUCN Red List.

In Legends and Culture

The peacock has been a prominent feature in Indian literature as its resplendent beauty is a source of inspiration for many. In popular legends, when the peacock displays its glorious plume, it’s a sign of rain.  They have iconic status as the carrier animal of the Hindu god Kartikeya. Lord Krishna was always depicted with a peacock feather in his headdress. In Buddhist philosophy the peacock represents wisdom. The peacock and its feather motifs are prominent features in Mughal architecture. The peacock and the peacock feather is still a popular motif to be used in logos, textile patterns as well as designs.





THE MAGIC AND MYSTERY OF BIRDS By Noah Strycker (Souvenir Press £18)

Last week’s news that half the world’s wild animals have disappeared in the past 40 years should depress and anger every right-thinking person.

It’s not just exotic species we should be mourning, but British birds such as the corn bunting and the northern lapwing. Needless to say, it’s all the fault of humankind — greedy, selfish, short-sighted and thoughtless as ever. The albatross, for example, is on the verge of extinction because too often when it dives for fish it snares itself instead on the hook at the end of fishing long-lines.

If you think this isn’t your business, you couldn’t be more wrong. Ornithologist Noah Strycker’s illuminating — and, actually, rather moving — new book is a welcome reminder that we have much more to learn from the animal kingdom than we can even begin to know.

There are parallels between ourselves and birds: reproduction, movements, daily rhythms, communication, navigation and intelligence

Asking searching questions about why birds behave as they do, he offers poetic insights into our own existence.

A bird-lover since childhood and now a world-renowned ornithologist, he lists many ways in which there are parallels between ourselves and birds: reproduction, movements, daily rhythms, communication, navigation and intelligence. And he demonstrates how much better human society might be if we took the lessons of the birds to heart.

Birds find their way naturally, by means of methods humans have had to discover and invent, like starlings

Anybody who watched the extraordinary television series that attached cameras to birds in flight will be well aware of their miraculous abilities to wing their way across oceans and through storms, yet still land in the right place.

Birds find their way naturally, by means of methods humans have had to discover and invent, including magnetic fields, polarised light, echoes, ‘map’-reading, and infrasound. Strycker sounds proud when he writes: ‘You can blindfold a bird, cover its nostrils, cover its ears, transport it far from home in a magnetised cage and, more often than not, it will still manage to find its way home.’

After describing those magnificent movements of murmurations of starlings (like great, sweeping skeins of smoke), he concludes that explanation takes us beyond mere science.

To him, the beauty of the bird movement is as beyond scientific analysis as a Renaissance masterpiece — and the miracle of seemingly pointless beauty is itself a lesson.

As one critic has correctly pointed out, Strycker has the mind of a biologist, yet he writes like a poet. And what he has to tell us is fascinating. Unlike most mountain birds, which migrate south in the winter, the American nutcracker (similar to a woodpecker) not only stays put but actually lays its eggs during the brutal snowstorms of January and February. How does it survive? By stocking up.

Nutcrackers live on pine seeds, which they begin gathering in July, when pine cones first ripen, and continue harvesting until early winter. Carrying about a hundred seeds at a time in a special pouch under their tongue, they hide them under the soil in numerous locations in batches of just three or four.

And this, as Strycker notes, ‘is where nutcrackers transcend mere survival’. In just one season, a single nutcracker may store tens of thousands of pine seeds in as many as 5,000 different mini-caches. They don’t mark the spots where the seeds are hidden; indeed by the time they come to find them, the ground is often covered by snow. It’s an astonishing feat, achieved, as various experiments have proved, by them noting the landmarks near each cache.

The Australian fairy-wrens, with diminutive with violet crowns and long, shimmering blue tails, are all related to each other

And then there are the Australian fairy-wrens, diminutive with violet crowns and long, shimmering blue tails. Strycker spent months observing them in a six-mile stretch of creek and discovered they were all related to each other, ‘a sprawling family of a hundred siblings, uncles, cousins, grandparents and occasional newcomers’ who all took care of each other’s young — proving humans are not the only species capable of altruism. These are just some of the intriguing topics in this book.

The most moving chapter is about the albatross — the romantic, majestic bird of the freezing wastelands which can have a wingspan of 12ft and fly for 2,000 miles to pick up food for their hungry chicks. Yet even though they spend interminable amounts of time on the wing, this beautiful creature mates for life.

Twenty years after the first famous dancing courtship ritual (when they face each other, stretching huge wings while they dip and canoodle) they will be nesting with the same partner. The author comments: ‘Personally I think albatrosses feel love even more intensely than we do, and available evidence seems to back me up.

The Nazca booby is unusual in the bird world as it is known for routinely slaughtering its own siblings in the nest

‘No matter what category of affection you study, albatrosses beat us every time.’

Don’t forget that only about 5 per cent of the world’s 5,000 mammal species are socially monogamous. Strycker points out that about 40 per cent of new human marriages in the U.S. will end in divorce, ‘which places us on about the same level as the Nazca booby, a type of seabird known for . . . routinely slaughtering its own siblings in the nest.’

But albatrosses stay faithful and are good parents: ‘When they commit they quit the singles scene’ and ‘spend less time dancing and more time raising their chicks’.

Do you see what I mean about us needing to learn lessons from the birds?

In this, the last chapter, Strycker reaches new heights of beauty and imagination when he describes what he has seen — an albatross pair sleeping with the head of one bird pillowed on the breast of another, or tenderly caressing each other’s heads. I love that one of the world’s leading ornithologists can write: ‘Different people report seeing various things deep in the inky-black eyes of the albatross — wisdom, serenity, wilderness, peace, endurance — which are well and good, but all I see is love.’

For centuries, we have considered ourselves superior to all the other creatures who share this planet. Remote from nature, we think we know everything and exploit the members of the animal kingdom as our inferiors.

But writers such as Strycker remind us that, in many ways, they are more complete and more gifted — extraordinary and complex nations of their own, moving to an unseen music that we will never be able to hear.
