Bat droppings, or guano, can be used as fertilizer. Many eat insects. Some bat species in other countries eat fruit or nectar and even fish. Vampire bats, a small group that lives in Central and South America, feed on animal blood. Like all mammals, young bats feed on mother's milk.
Some bats spend the winter in underground caves.
These little brown bats were photographed hibernating in Connecticut. This game is very similar but is played on land. One person is the bat and another is the moth. Both must stand in a circle made by the other players. The bat is blindfolded.
