Why do garganey birds migrate to India?

Birds migrate from place to place in search of food and better living conditions. Migration to India is mostly from places which experience severe winters and the water bodies freeze over. Snow often covers the ground also, depriving birds of food and warm places to live in. They migrate long distances to warm places like Asia, Africa and Central America where winters are not so severe and food is available in plenty. After the severity of winter reduces in Equope, Central Asia and Chinese and Russian cold regions the visitors return from the wintering locations. They usually breed in the places from where they migrate to India.
