Environment & Crow

"House Crows are omnivorous scavengers with a wide-ranging and opportunistic diet. They eat absolutely everything that is edible, and some that may not even be so. The crow feeds largely on refuse around human habitations, carrion, small reptiles, insects, small invertebrates, eggs, nestlings, plants, grain and fruits etc... If the studies on corvids are used as a guide, then the House Crow needs about 300g of food daily. Much of what the average House Crow eats is garbage or human waste – but not all."

"total of 34 million crows in the country"

"So total garbage cleared by crows is:
Urban crows [1,91,00,000 x 165g] = 3,150 tons/day = 11,50,000tons/year
Rural crows [1,50,00,000 x 110g] = 1,650 tons/day = 6,00,000tons/year"

"and the final contribution by House Crows can easily cross Rs 400crores (about US$ 90mn) annually – and this is citizen tax savings!"
