Migratory Birds Flock to Bihar Weeks Early, Signaling Harsh Winter

As of October 15th, 2025, migratory birds have arrived weeks earlier than usual in the Indian state of Bihar. According to Dr. Gopal Sharma, the Bihar coordinator of the Indian Bird Conservation Network, many species have reached their winter destination by the end of September instead of their typical mid-October arrival.

The early migrants include a variety of birds such as the Common Sandpiper, Red-necked Falcon, Glossy Ibis, Grey-headed Lapwing, Stork-billed Kingfisher, and White Wagtail. The district coordinator of the Asian Waterbird Census also reported a rise in sparrows and Baya Weavers in the region.

Experts have attributed the birds' premature arrival to temperature changes as well as potential improvements in water habitat conservation efforts in Bihar. While this could indicate a positive development in the local ecosystem, it also raises concerns about disruptions to migratory patterns and potential population declines if resources become scarce.
