Teesta Barrage counts 10K winged guests
The winged guests generally fly in from Tibet, China, Mangolia, eastern parts of Europe and Siberia. Many of these also come from Ladakh. Rasik Bill, Mahananda Barrage, Gazoldoba and Nararthali are some of the common places where thousands of migratory fowls of different species normally come in during the first or second week of December every year to spend the winter.
