One of an interesting behavior study in life of birds is their foraging behavior which is directly connected to the distribution and abundance of food resources in their habitat. To study the foraging behavior of Sarus Cranes we searched for papers, review, we focus on the behavioral patterns of foraging in sarus. Sarus cranes are generalists and opportunists, feeding on a remarkably wide variety of plant and animal foods. Sarus cranes mostly forage in shallow water (usually < 30 cm (1 ft) depth of water) or in fields, often seen probing in mud with their long bills. They are omnivorous, eating both plants and insects during breeding season, aquatic plants, fish (perhaps only in captivity), frogs, crustaceans and seeds. Infrequently preying larger vertebrate prey such as water snakes, in a few cases sarus crane feed on the eggs of birds and turtles also. Tubers, corms of aquatic plants, grass shoots as well as seeds and grains from cultivated crops such as groundnuts and cereal crops such as rice are the form of plants food, they intake. Sarus Crane forages in both wetlands and agricultural fields. Nowadays impact of human disturbances, cutting of trees, destruction of wetlands, food unavailability, industralisation, predators, poaching are crucial factors affecting the foraging behavior of Sarus cranes. To solve this problem, we need to re-construct wetlands develop community awareness and conduct various kinds of awareness programs.
