Patna: In a promising development for environmentalists and bird watchers, migratory birds have begun arriving in Bihar well ahead of their usual schedule, with sightings reported as early as the first week of September. This early arrival is being seen as an auspicious sign for both the ecological health of the region and the coming winter season.
According to Dr. Gopal Sharma, State Coordinator of the Indian Bird Conservation Network (under the Bombay Natural History Society) and Interim Director of the National Dolphin Research Center, Patna, this early migration may be a sign of a harsh winter ahead and is likely to be accompanied by a larger number of birds in the coming months.
Notable Migratory Birds Spotted in September
Bird species that are usually seen in mid-October have now been sighted much earlier across the plains of Bihar. These include:
- Grey-headed Lapwing
- Common Sandpiper
- Glossy Ibis
- Red-necked Falcon
- Stork-billed Kingfisher
- White Wagtail
Dr. Sharma attributes this early arrival to a combination of factors, including temperature fluctuations, irregular weather patterns, and improved water body conservation.
Environmental Indicators: Positive Signs for Habitat Health
Experts believe that this trend is not just a seasonal anomaly but could reflect a positive ecological shift in the region. Improved natural habitats—such as rivers, wetlands, ponds, forests, and agricultural fields—are creating favorable conditions for both migratory and native birds to live and breed.
“Early bird migration may indicate an upswing in environmental quality. It’s a hopeful sign for conservation efforts,” said Dr. Sharma.
Increase in Native Birds Like Sparrows and Weaver Birds
The District Coordinator of the Asian Water Bird Census also reported a notable increase in the population of native birds, particularly sparrows and weaver birds.
This increase is being linked to several factors:
- Crop harvesting, which leaves behind grains and insects
- Pre-winter preparations by birds
- Improved conservation initiatives at the local level

Bihar Emerges as Key Breeding Site for Garuda (Great Eagle)
Among major developments, Bihar has now emerged as a leading breeding site for the Garuda, a large raptor also known as the big eagle, known for its nesting expertise.
This bird, which is primarily found in:
- The Brahmaputra Valley of Assam
- The Kadwa Diara region of Bhagalpur, Bihar
…has now placed Bihar in a top position among India’s three known breeding grounds for the species.
Conclusion: Hope for Biodiversity and Conservation
The early arrival and rising numbers of both migratory and native birds are being interpreted as strong indicators of improving biodiversity and ecological health in Bihar. Environmentalists believe these developments bolster hopes for sustained conservation success in the state and across the eastern Gangetic plains.
