Trichy: Rare sightings of the woolly-necked stork are being reported from the paddy fields near Thanjavur. Researchers believe this sighting could be a significant indicator of the species' range expansion or the effects of environmental changes in the region.
Although the woolly-necked stork is native to India, it is most commonly found in the northern states. "While it occasionally appears in southern India, particularly Tamil Nadu, during the migration season, its presence in Thanjavur district after the migration period has ended is considered a very rare event," said Sathishkumar Rajendran, researcher and founder of the Endangered Wildlife and Environmental Trust (EWET).
S Sriram, a birdwatcher, first spotted the bird in the paddy fields near Vannarapettai village and reported it to the researchers. Based on this information, Sathishkumar Rajendranand EWET coordinator Viswapream CA visited the location, observed the bird in person, and documented the sighting through photographs.
The woolly-necked Stork (Ciconia episcopus) is a medium-sized wading bird. It typically inhabits open grasslands, paddy fields, riverbanks, ponds, and other wetland areas.
Its primary diet consists of fish, frogs, small reptiles, insects, and other aquatic creatures. The species is classified as ‘near threatened' on the IUCN Red List.
According to the researchers, these birds are usually seen alone or in small groups. During the breeding season, they build nests on tall trees and lay two to four eggs. They play an important role in maintaining ecological balance.
Researchers believe that the appearance of this bird in the Thanjavur region could indicate either an expansion of its range or the impact of ongoing environmental changes. They have now initiated continuous monitoring and documentation efforts to track further sightings of the species in other areas.
