Captive-bred GIB released into wild killed by fox

A captive-bred Great Indian Bustard was killed by a desert fox in Jaisalmer’s Desert National Park. The six-month-old male had entered the wild only the previous Wednesday. Its death was a serious setback because the release programme aims to rebuild a critically endangered species through experimental rewilding.

The bird was attacked at a natural watering hole. Scientists and forest officials noticed the incident through satellite tracking, which alerted a control room at the breeding centre in Sam. When a team reached the site, the fox had disappeared. Only shattered remains and feathers were left.

Officials collected blood samples and retrieved the tracking device. The incident prompted scientists to review release protocols and conservation safeguards. Seven other bustards will be released only after that review. Three other released birds remained safe and continued moving through the park.

The Great Indian Bustard, or GIB, is a large ground-dwelling bird native to India. It is considered critically endangered, meaning its wild population faces an extremely high risk of extinction. The article identifies it as a species needing a dedicated conservation plan and population restoration effort.

The article does not explain all the causes behind the GIB’s decline. Established conservation knowledge links the species’ crisis to threats such as habitat loss, disturbance, hunting and collisions with power lines. Those wider threats help explain why captive breeding and carefully managed rewilding are being attempted.

The Jaisalmer programme bred birds at the Wildlife Institute of India’s Sam centre before releasing them into the Desert National Park. One six-month-old male was killed by a desert fox. The setback has led officials to review safeguards before releasing seven more birds.

The first phase of the experimental rewilding programme selected 11 captive-bred Great Indian Bustards for release. All were around six months old. The number shows that this was a small, closely monitored trial rather than a large-scale release.

Two satellite-tagged male birds were released at the Sudasari site on October 4. Two more male birds were released there the following Wednesday. One of those two was killed by a desert fox on Sunday. This means six birds had been released by the time of the death: the four males released in the reported steps, plus two earlier birds included in the programme’s initial release count.

The article states that three birds released into the wild remained safe after the attack. Seven birds from the original group had not yet been released. Their release is now paused pending a review of safeguards.

The fox attack has changed the programme’s immediate timetable. Wildlife Institute of India scientists will review the release protocols and conservation measures used for captive-bred Great Indian Bustards. The goal is to reduce the chance of another avoidable loss while keeping the wider rewilding effort on course.

The clearest practical change concerns the seven bustards still waiting for release. Officials will not release them until they have completed a thorough review of programme safeguards. The released birds will also continue to be monitored through satellite tracking, allowing teams to follow their movements and respond to alerts.

Officials do not describe the event as proof that rewilding should stop. They call it natural predation by a native desert fox, while recognising the need to strengthen protections. The three other released birds were reported safe, and the review will guide the next release decisions.

Officials describe the attack as a natural predation event because desert foxes are native predators in the park’s landscape. Releasing a captive-bred bird into the wild exposes it to the same natural dangers faced by wild animals. The attack therefore reflects the difficulty of restoring a species in its habitat.

The six-month-old male was killed at a natural watering hole. Teams were already conducting regular patrols and using protective measures, but those actions could not prevent every encounter with a predator. Satellite tracking detected the incident and helped officials locate the bird, but it could not stop the attack.

The event still matters for programme design. Scientists are reviewing safeguards before releasing seven more birds. Officials say predation is bound to happen in the wild, while the WII director said the incident should strengthen determination to meet the conservation plan’s objectives.

Satellite-tracking devices give scientists a way to follow released birds after they leave the breeding centre. They provide movement information over a wide and difficult landscape, where teams cannot watch every bird continuously. This is especially useful during experimental rewilding.

In Jaisalmer, scientists and forest officials monitored the birds from a control room at the Sam breeding centre. Satellite tracking alerted them when the six-month-old male was attacked. A team then travelled to the location, where officials retrieved the device and collected blood samples from the remains.

The system also supports routine protection of surviving birds. Forest department sources said the three other released birds were safe and continued moving across the park, with their movements regularly tracked by satellite. The technology cannot prevent every natural attack, but it helps teams detect incidents, locate birds and assess how they adapt.

Captive-bred animals are moved from controlled care into environments where food, shelter, predators and weather cannot be managed in the same way. They may need to develop survival skills while facing risks immediately. Reintroduction therefore requires careful preparation, monitoring and safeguards.

The released bustard in Jaisalmer had been bred at the WII’s Sam centre and was around six months old. It was killed by a desert fox at a natural watering hole only days after release. The incident shows how quickly a captive-bred animal can encounter a natural threat that staff cannot fully control.

Satellite tracking, patrols and protective measures help teams observe and respond, but they cannot remove every wild risk. The attack has led scientists to review release protocols before releasing seven more birds. The three other released bustards were reported safe and continued moving through the park.
