There’s hope for the rare Great Indian Bustard (Indian Express)

Mains Paper 3: Environment
Prelims level: Great Indian Bustard
Mains level: Challenges ahead to conservation of species

Context:

• Once the frontrunner to be named India’s national bird, the Great Indian Bustard has long been on the brink of extinction.
• The Great Indian Bustard (GIB), is one of the heaviest flying birds, and is found mainly in the Indian subcontinent.
• Barely 150 of these birds are estimated to be surviving now globally. However, a major conservation effort launched about four years ago is bringing a ray of hope.

Nine chicks:

• Since June last year, nine GIB eggs collected from the Desert National Park in Jaisalmer where a conservation centre has been set up, have hatched, and the chicks are reported to be doing well.
• This is the largest number of hatchings reported within a six-month frame by any GIB conservation programme in the world, say officials.
• Forest officials have identified seven females and one male among the GIB chicks; the sex of the ninth and youngest chick, which hatched a couple of months ago, is not yet known.
• The GIB is known to eat insects, harvested foodgrains, and fruit. “The uncontrolled use of pesticides and insecticides in farms has badly hit their food habitat,” said Tomar, who took over as the project head in early 2019.
• Vanishing grasslands, and attacks by dogs and foxes have contributed to the threat to the GIB’s survival.

Conservation:

• The Ministry of Environment, Forest and Climate Change, and the Wildlife Institute of India (WII), Dehradun, are working to save the GIB.
• The Ministry has allotted special funds to the tune of Rs 33 crore, a part of which was used to set up the incubation and chick-rearing centre in Jaisalmer.
• In a report submitted to the Ministry in November 2018, the WII said extensive land surveys have been carried out to locate suitable habitats for the chicks.
• Officials have zeroed in on 14 spots, based rainfall, accessibility, proximity to wild source, habitat and topographic suitability, availability of water, temperature, etc., and identified Sorsan as the site most conducive for their rearing.

Challenges:

• Male birds reach sexual maturity between the ages of 4 and 5; females at age 3-4. Generally, the GIB lives up to age 15 or 16, experts said.
• A female lays an egg once in 1-2 years, and the chicks’ survival rate is 60%-70%.
• Being such long-lived and slow reproducing species, adult mortality remains high.
• According to the WII report, the bird was once abundant in Kutch, Nagpur, Amravati, Solapur, Bellary, and Koppal districts in the states of Gujarat, Maharashtra, and Karnataka.
• Karnataka has expressed interest in working with us, but there is nothing concrete from Maharashtra so far.

Way ahead:

• Globally and in India, high voltage power lines are a major threat to the GIB.
• The bird has poor frontal vision, which restricts it from spotting power lines early. About 15% of the population (dies) due to the power lines in Jaisalmer alone.
• This, in comparison to the natural cause of deaths contributed only 4% to 5% cases.
