Chennai, Jan 29 (NationPress) The Vettangudi Bird Sanctuary in Tamil Nadu has experienced a significant upsurge in migratory bird numbers this season, as reported by forest officials.
This year, around 3,500 to 4,000 birds have been recorded at the sanctuary, marking a dramatic increase from the 800 that were noted in 2023.
The Tamil Nadu Forest Department highlights that nearly 20 species of migratory birds visit the Vettangudi Bird Sanctuary each year.
Among these are the Egret, Indian Spot-Billed Duck, Darter, Asian Openbill Stork, and Black-Headed Ibis.
Many of these avian visitors travel thousands of kilometers from places such as Australia, Europe, and Southeast Asia to arrive at the sanctuary.
Covering an area of 36 hectares, the Vettangudi Bird Sanctuary is located in the villages of Kollukudipatti and Vettangudipatti along the Madurai-Karaikudi Highway.
Migratory birds come to this sanctuary primarily for roosting and breeding. Local residents believe that the presence of these birds serves as an indicator of the monsoon’s intensity.
“These birds offer clues about the rainy season. Nesting in low-lying areas suggests lighter rainfall, while nesting in higher terrains points to heavier rain,” explained Manikantan Thevar, a local bird enthusiast.
To safeguard the birds from poaching, the forest department has assigned anti-poaching watchers.
Moreover, they have removed unwanted trees and shrubs, replacing them with native Nattu Karuvelam trees to enhance the habitat.
Efforts have also been initiated to ensure a reliable food supply for the birds.
Fish fingerlings have been introduced into nearby bodies of water, bolstering the food chain within the sanctuary.
To mitigate natural threats, authorities have relocated 32 monkeys and two pythons from the sanctuary, thus minimizing predatory risks to the birds and their eggs.
Acknowledging the sanctuary's proximity to a national highway, the forest department, in partnership with the Salim Ali Centre for Ornithology and Natural History, conducted a study on the effect of sound waves on migratory birds.
Meanwhile, the Pallikaranai Marshland in Mettukuppam, Thorappakkam, has welcomed over 10,000 birds spanning 100 different species.
Among them, 70 species are migratory, including rare birds like the Garganey, Northern Shoveler, Eurasian Teal, Eurasian Wigeon, Ruff, and Western Marsh Harrier.
Bird watchers attribute this increase to the marshland’s plentiful food supply and favorable habitat conditions.
The Pallikaranai Marshland has undergone significant restoration efforts, including the removal of 52 illegal encroachments under the oversight of the National Green Tribunal (NGT).
The relocated squatters allowed the wetland to regain its natural state, creating an undisturbed sanctuary for both migratory and local bird species.
With diminished human interference, the marshland has transformed into a thriving habitat, attracting thousands of birds each season.
Forest officials, along with bird watchers, continue to monitor the ecosystem, ensuring its preservation as a haven for avian biodiversity.
The increase in migratory birds at both the Vettangudi Bird Sanctuary and Pallikaranai Marshland underscores the success of conservation initiatives and highlights the necessity of safeguarding natural habitats for these seasonal visitors.
