Salt pans witness early arrival of migratory birds in Kanniyakumari
Migratory birds have arrived earlier than usual at the salt pans of Kanniyakumari, signaling a shift in seasonal patterns. Experts note that despite habitat shrinkage, these wetlands remain vital stopovers for species on the Central Asian Flyway.
Why it matters
Early migration patterns serve as an important indicator of environmental and climate-related changes affecting global biodiversity.
The arrival of migratory birds, particularly waders, has begun early this year at the salt pans of Puthalam, Andivilai and Swamithoppu in Kanniyakumari district. Several birds that were ringed at these salt pans last year were also spotted at the sites, indicating their return to the wetlands.
The salt pans of Puthalam, Andivilai and Swamithoppu, which were once extensively used for salt production, have considerably shrunk over the years. At present, only a few patches are being used for salt production. However, the reduction in salt producing areas has not prevented the migratory birds from returning to these sites.
Waders have started arriving a few days earlier than usual this year, with the salt pans providing feeding and resting grounds for the birds during their long-distance migration along the Central Asian Flyway.
