Bats are active at night seeking their food, which consistsdepending on the species-of insects, fruits or even of blood. Thus, their hidden way of life caused fear, especially in those cases, when many bats fly simultaneously around houses or around heads of persons, since they live together in groups of often more than 100-150 animals hiding themselves during daytime in the treetops (e.g. plant eating flying foxes e.g. in Australia) or in tunnels of railways, galleries of closed mines, in old, rottening empty buildings on practically all continents except for Antarctica.	./cache/cord-017407-nc9cyu2u.txt	./txt/cord-017407-nc9cyu2u.txt
