Great bats

Seldom-seen, the grey and purple great bat is found in remoter parts of Mirkwood. Little is known of its habits. It eats night-flying birds (e.g., owls), large spiders, and various rodents, although larger individuals have been known to fell a small bear. The great bat sucks blood (always a tempting notion to those who dislike bats, even the small insectivorous kind) from its victims, and feeds on the softer flesh of its prey.
