Greater Flamingos Spotted at Veeranam Lake

Summary of Findings on Greater Flamingos in Veeranam Lake

Key Facts:

• Species Observed: Greater flamingos.
• Location: Veeranam Lake, Cuddalore District, Tamil Nadu.
• Total Sighted: 18 greater flamingos.

Contextual Information:

• Migration Patterns:
  • Greater flamingos typically migrate from the Gulf of Kutch to the eastern coast of India during winter.
  • Normal coastal habitats include areas like Point Calimere Wildlife Sanctuary, Muthupettai Lagoon, and Pichavaram mangroves.

Factors Influencing Altered Migration:

• Super El Niño: Severe weather phenomenon affecting climate patterns, likely altering migration routes.
• Water Deficit: Significant reduction in rainfall and river flow.
  • Cauvery River: Reduced flow contributing to dry coastal mudflats.
• Monsoon Impact: Low rainfall during the Southwest monsoon season has exacerbated food scarcity in coastal habitats.

Research Insights:

• Foraging and Habitat Use:
  • The receding water levels at Veeranam Lake have created shallow areas favorable for greater flamingos to forage.
  • Plankton and other food resources may be concentrated due to evaporation, making the lake a temporary feeding ground during migration.

Future Monitoring Requirements:

• Continuous monitoring of greater flamingos is essential to understand:
  • How these coastal species adapt to using inland wetlands under stress conditions of coastal ecosystems.
  • The sustainability of Veeranam Lake as a habitat during their migratory period.

Implications:

These observations highlight the impact of climatic changes on wildlife behavior and habitat use, which may inform conservation strategies and environmental policies regarding wetland management and the protection of migratory bird routes.
