A hailstorm in the buffer zone of Pench Tiger Reserve in Madhya Pradesh has killed thousands of birds. Any thunderstorm that produces hail, which reaches the ground, is called a hailstorm. Hail is solid precipitation made of balls or irregular lumps of ice, each of which is called a hailstone. Hailstones consist mostly of water ice and measures between 5 mm and 15 cm in diameter.
