Overview This weekend, Cyclone Ditwah brought an unexpected event to Tamil Nadu's shore: two female Amur Falcons were blown off their migratory course and landed in Point Calimere (Kodiyakarai) . The sighting highlights the impact of extreme weather events on wildlife migration patterns. About Amur Falcons The Amur Falcon ( Falco amurensis ) is a small raptor that breeds in southeastern Siberia and northern China. It is renowned for its extraordinary long-distance migrations. Migration Distance: Approximately 40,000 km annually. Migration Route: Cuts across the Central Asian and West Asian flyways before crossing the Arabian Sea to reach southern Africa. Typical Indian Route: Usually passes through the Gujarat-Maharashtra corridor, making the Tamil Nadu coast an unusual location. Past Sightings in Tamil Nadu This is not the first instance of Amur Falcons being sighted in Tamil Nadu due to cyclonic activity: 2020: First-ever sighting in Point Calimere after cyclones Nivar and Burevi . November 2024: Two more Amur Falcons were sighted during Cyclone Fengal . November 2025: Two female Amur Falcons appeared close to the BNHS Bird Migration Study Centre during Cyclone Ditwah . Expert Opinion S. Sivakumar , Assistant Director at BNHS , emphasized the role of cyclones in altering migratory trajectories. "This is not their regular migratory route. Amur Falcons normally pass through Gujarat and Maharashtra. Strong cyclonic winds can blow them far from their viable path. We first recorded the species here in 2020. Now, during Cyclone Ditwah, two have appeared again," he stated. Significance for the Birds For the Amur Falcons, Kodiyakarai represents an unscheduled stop, a rare pause in their otherwise relentless, transcontinental journey.
