Great Indian Bustard: Experts hail breakthrough in bid to save native bird

Last month introduced excellent news for the nice Indian bustard, a critically endangered chicken discovered primarily in India.

Wildlife officers within the western state of Rajasthan have carried out the primary profitable hatching of a chick by synthetic insemination.

A lone grownup male in certainly one of two breeding centres in Jaisalmer metropolis was skilled to supply sperm with out mating, which was then used to impregnate an grownup feminine on the second centre some 200km (124 miles) away.

Officials mentioned the event was essential because it has opened up the potential of making a sperm financial institution.

Over the years, habitat loss, poaching and collisions with overhead energy strains have effected nice Indian bustards. Their numbers have fallen from greater than 1,000 within the Sixties to round 150 at current.

Most of them are present in Jaisalmer and therefore, conservation activists say that the chicken’s habitat within the metropolis ought to be protected. But this land can also be prime actual property for renewable vitality companies, presenting authorities with a singular conservation problem.

The nice Indian bustard might not be as nicely often known as the peacock (India’s nationwide chicken) nevertheless it’s simply as spectacular, says Sumit Dookia, a conservation ecologist who has been learning the chicken for near a decade. The huge chicken, which weighs between 15kg and 18kg, is without doubt one of the largest flying birds in India.

It as soon as had a prolific presence within the nation and was present in not less than 11 states, however in the present day, its inhabitants is confined to Rajasthan, whereas a handful could be noticed within the southern state of Karnataka and the western state of Gujarat.

The shy chicken performs an essential function within the meals chain by preying on rodents, snakes and different pests and can also be the state chicken of Rajasthan, the place it’s referred to as ‘Godawan’ by locals.

But among the chicken’s distinctive evolutionary traits are clashing with human interventions, making it susceptible to extinction.

For one, the nice Indian bustard has good peripheral imaginative and prescient however poor frontal imaginative and prescient, making it troublesome for them to identify energy strains till they fly too near them. Their massive dimension makes it troublesome for them to rapidly change their flight path they usually find yourself colliding with the cables and dying.

“Their vision could have developed like this as the bird spends a large amount of time on land,” says Mr Dookia. It additionally lays its eggs on the bottom, and not using a nest or another type of safety apart from the watchful eye of the mom and this may need prompted it to develop good facet imaginative and prescient, he provides.

The nice Indian bustard additionally has distinctive breeding habits. The chicken lays only one egg at a time and spends the following two years caring for its offspring.

“Since it reaches maturity at around four years of age and lives for 12-15 years, it lays just about four-five eggs in its lifetime and many of these eggs are destroyed by predators,” Mr Dookia says.

Conservationists say that over the previous few years, the nice Indian bustard’s habitat in Jaisalmer has been overrun by photo voltaic and wind vitality farms, resulting in a rise in flying accidents.

“The increased human presence has also created more filth, attracting stray dogs who kill the birds or destroy their eggs,” Mr Dookia says.

To enhance the chicken’s inhabitants, the federal government of Rajasthan collaborated with the federal authorities and the Wildlife Institute of India to launch a conservation breeding centre at Sam metropolis in 2018. Another breeding centre was arrange at Ramdevra village in 2022, says Ashish Vyas, a high forest official in Jaisalmer.

As a primary step, researchers collected eggs discovered within the wild and hatched them in incubation centres. “Currently, there are 45 birds in both the centres,14 of which are captive-bred chicks (including the one born through artificial insemination),” he provides.

The plan is to additional enhance the chicken’s inhabitants after which ultimately launch them into the wild. But conservationists say that that is simpler mentioned than finished.

This is as a result of the birds born in these breeding centres have imprinted on human researchers (in different phrases, they’ve fashioned shut bonds with their human caretakers) and have misplaced about 60-70% of their capacity to outlive within the wild, says Mr Dookia.

“Human imprinting is necessary for feeding and handling the birds but it also makes them lose their natural instincts. It will be extremely challenging to re-wild them, especially if there’s no habitat left for the birds to be released into,” he provides.

The lack of habitat has additionally resulted in one other drawback: researchers have seen that the birds, which used emigrate throughout states, have virtually fully stopped doing so. Even in Jaisalmer, the place the birds are present in two pockets – Pokhran within the japanese a part of the town and the Desert National Park within the west – there’s hardly any cross-migration, says Mr Dookia.

It’s seemingly that the birds have stopped migrating over massive distances in response to flying accidents, he provides. This will increase the danger of inbreeding, which might lead to start defects.

“Thus, the only solution to conserve the great Indian bustard is to preserve its natural habitat,” he says.

But a Supreme Court judgement from April has made conservationists uneasy.

The court docket overturned an earlier interim order, which had instructed Rajasthan and Gujarat to prioritise transferring energy cables underground in nice Indian bustard habitats. The order had created a furore amongst renewable vitality companies, who mentioned that this might price them billions of rupees and nearly kill their enterprise.

In its newest judgment, the court docket noticed that individuals had the suitable to be free from the dangerous results of local weather change and that shifting massive sections of energy cables underground might not be possible for companies from a financial and technical standpoint.

It additionally directed {that a} committee be set as much as look into the feasibility of transferring energy strains and the efficacy of chicken diverters – units which have reflectors and are hooked up to energy cables to alert birds about their presence.

While corporates have hailed the highest court docket’s judgment, conservationists and a few authorized specialists say that it is problematic because it pits one good trigger towards one other.

“The judgment brings into focus a flawed understanding of the interplay between climate change, biodiversity and development issues,” ecologist Debadityo Sinha wrote in a column.

He famous that many highly-populated cities in India have underground energy strains and that different states have taken such a step to guard different chicken species previously. He additionally identified that though transferring energy cables underground is pricey, it is more likely to quantity to a fraction of a agency’s whole earnings.

Mr Dookia says that one of many causes renewable vitality corporations are flocking to Rajasthan is due to the low price of land.

“There’s also not much research on how these renewable energy farms will impact the state’s climate and ecology in the long run,” he says.

“So it’s not just the bird’s future that hangs in the balance, it’s also man’s.”
