The Indian Bustard: Threatened due to Habitat Loss and War

The Indian Bustard 

The Indian Bustard, scientifically known as Ardeotis nigriceps, is a large and majestic looking bird, native to the Indian subcontinent. It is known for its striking appearance and unique behavioral traits, i.e., females lay a single egg, while males have a booming call. The Bustard faces major threats that endanger its very survival. The recent war between Indian and Pakistan has compounded these threats to the birds’ habitats.
 
Physical Characteristics:
The Bustard is a tall and heavy bird, with an average height of about 3 to 4 feet (90 to 120 cm) and weighing about 16 to 18 kg, making it one of the largest flying birds in the world. Its wingspan measures around 6.5 to 7.5 feet (2 to 2.3 meters), and it possesses long legs adapted for walking and running in its dry grassland habitat. The male has a distinct black crown and breast, while its back and wings have shades of brown. The female, on the other hand, has a more sober sandy-brown plumage. 
 
Habitat and Distribution:
The Bustard once thrived across the vast grasslands and semi-arid regions of India and Pakistan. Historically, it could be found in areas such as Rajasthan, Gujarat, Madhya Pradesh, Maharashtra, and Andhra Pradesh. However, due to habitat loss and fragmentation, the species' distribution has drastically diminished. Today, the Indian Bustard is chiefly found in small areas of its earlier range, such as Nanaj Wildlife Sanctuary (Maharashtra), the Thar Desert region of Gujarat, Rajasthan and adjoining Pakistan, where the right type of grassland habitats still exist. Back in 2012, I had the privilege to see these birds in their natural habitat in Nanaj, Maharashtra, even though it was a long distance sighting.  
 

The Bustards mainly inhabit open grasslands, shrublands, and semi-arid plains. These extensive plains offer a perfect blend of tall grasses for nesting and foraging for seeds, insects and sometimes, mice and lizards.

Threats to its existence:
The Indian Bustard faces numerous threats that have led to its endangered status. It is listed as Critically Endangered on the IUCN Red List and the National Wildlife Action Plan (2002-2016). Its preference for areas undisturbed or with minimal human activity, makes it particularly susceptible to habitat destruction caused by urbanization, agriculture expansion, and infrastructure development like roads and electricity pylons and windmills. The threats in Pakistan are mainly due to illegal hunting. In addition, human settlements like resorts, have drastically reduced suitable breeding and foraging grounds for the species. Fragmentation of its habitat into smaller pockets instead of large contiguous areas has hindered its ability to disperse, find mates, and establish new territories. 
A major threat is the increased presence of power lines and wind turbines within the bird's range. These structures pose a high risk of collision and electrocution, especially since the birds fly at low levels.
As per latest reports, the numbers have dropped drastically in Nanaj Wildlife Santuary.
 
Conservation Efforts: 
Conservation initiatives are being undertaken to mitigate the challenges faced by the Indian Bustard. Several protected areas, such as the Desert National Park, Great Indian Bustard Sanctuary, and Karera Wildlife Sanctuary, have been established to protect their habitats. Additionally, efforts are being made to engage local communities and raise awareness about the importance of conserving this iconic species, once in the race to be declared as India’s national bird. Efforts are being made to protect its habitat under the initiative, Integrated Development of Wildlife Habitats of the Ministry of Environment and Forests, Government of India
 
An artificial breeding facility has been established at Sam, Jaisalmer for rearing chicks. (During the recent border shelling with Pakistan, the bustard chicks were shifted from Jaisalmer to Alwar; refer article in HT, May 15, 2025).
The government is also considering moving overhead electricity cables to underground pathways in the specific zones (as directed by the Supreme Court). Collaborative efforts between different state governments, Ministry of Environment and Forests, and local communities hold the key to ensuring the survival of this majestic bird.

Cloud Seeding: Potential Solution for Rainfall Deficiency in India

Cloud seeding offers a viable and scientifically proven method to induce artificial rain and address rainfall deficiencies.
 
We are now almost halfway through the annual monsoon season and the rainfall patterns continue to show large variability. There exists the distinct possibility of deficient rainfall over the country. Until now, nine states have had deficient rainfall, while only six states have received normal or excess precipitation. (Ref: IMD, see image below)
Consider the situation in Maharashtra; although parts of the state, including cities like Mumbai, Kolhapur, and Nagpur have been drenched by heavy rains, districts such as Nasik, Aurangabad, and Jalgaon have shown significant rainfall deficit. 
The deficient and uneven distribution of rainfall has also resulted in extremely low water levels in dams across Maharashtra. 
 
See Table below:

One potential solution to this problem is cloud seeding, a form of weather modification that can induce artificial rain, given the right cloud formations / conditions. This technology, though available for a long time the world over, remains un-utilized in India. The last time cloud seeding was under serious consideration was in the year 2012. In the past 12 years, there have been no efforts by the government to seriously consider cloud seeding to mitigate the rainfall deficiencies. Not one single time!
 

What is Cloud Seeding?

 

Cloud seeding involves dispersing silver iodide into the air which helps formation of nuclei for water condensation or formation of water droplets, leading to small-scale weather modification within the cloud. The water droplets gradually increase in size to fall down as precipitation or rainfall.
The process can be performed using aircraft fitted with devices to disperse silver iodide solution. It can also be done using ground-based generators, which release the seeding material into the atmosphere. Once these particles reach the clouds, they stimulate the formation of rain droplets, increasing the likelihood of precipitation.

Proven Positive Results
 
The efficacy of cloud seeding has been demonstrated in various parts of the world. Countries like the United States, China, Australia and UAE have successfully employed this technique to enhance rainfall and alleviate droughts. China has an extensive cloud seeding program, which is said to have increased precipitation by up to 10-15% in target areas, especially catchment areas of dams and water reservoirs.
 
Environmental Impact of Cloud seeding 
 
Cloud seeding can significantly impact ecosystems in the region. The point to note is, the impact is positive. Impact includes, changes in precipitation patterns, modifications to water bodies and ground water levels, and disturbance in natural habitats of animals.

Need for Immediate Action
 
Maybe we should consult China or the UAE, or maybe we have enough expertise, but no intent. There is an urgent need for targeted action right now to increase the chances of success. The satellite imagery from IMD shows there is very good cloud cover now, which can have positive results. Delaying efforts until August when there is sparse cloud cover, would only aggravate the situation, leading to further water scarcity and suffering for the agricultural sector.
Additionally, investing time and money into cloud seeding technology and infrastructure can help India solve the problem of unpredictable monsoons. A strong cloud seeding program by the government will not only address the current deficit, but will enable us to prepare for rainfall shortage in the future.

There exist several sub-species of this falcon, each adapted to the country of residence. The migratory variant captured in these pictures have a slightly lighter grey body.

They are solitary birds and skilled aerial hunters; either by scanning the terrain from air, or patiently observing from a lookout post, before striking with great speed.

Habitat

Chiefly near wetlands, or grassy plains near rivers. Occasionally found near urban habitations.

Food

Feeds on pigeons, doves, small birds, occasional rabbits and hare.
