Update on Bird Mortality Cases
Between August 24 and September 6, 2025, the NZP recorded the deaths of:
- 9 Painted Storks
- 3 Black-headed Ibises
- Out of these, 7 samples tested positive for the H5N1 Avian Influenza virus.
The last bird death in the water bird aviary occurred on August 28, and no new deaths have occurred in the isolation ward since September 6. Currently, two birds are recovering in isolation.
Additionally, 5 migratory Painted Storks died near the water pond, with 3 testing positive for the H5N1 virus. Importantly, no new deaths among migratory birds have been reported since September 1.
Samples and Testing
Environmental samples have been sent to the National Institute of High Security Animal Diseases (NIHSAD), Bhopal for screening. The test results are currently awaited.
So far, no symptoms of influenza-like illness have been observed in any other zoo animals, suggesting that the infection is confined to specific bird populations.

In response to the outbreak, NZP authorities have ramped up intensive sanitation and bio-security protocols. These include:
- Restricted movement near bird enclosures
- Regular disinfection of enclosures and surrounding areas
- Close health monitoring of birds and zoo staff
- NZP Remains Vigilant
The National Zoological Park assures the public that it remains fully vigilant and continues to take all necessary actions in accordance with standard operating procedures and expert guidelines to contain the avian flu outbreak.
