PH 10/11/92 Brown leaf-nosed bats, and Gray leaf-nosed bats, if also principal enemy among many other animals. But for humans colour of brown leaf-nosed bat is unmistakable: it has a white spot on its head. In contrast, at least in the absence of light, this kind of bat would be hard to see. But now we have a different problem. Brown leaf-nosed bats, and Gray leaf-nosed bats are known to eat "fruit" (mice? birds?) which they find on the ground or in trees. It seems that when fruit is scarce, these bats will move from one tree to another searching for food. But if the trees are far apart and there is no fruit on the ground between them, they may starve. If they do so, it is likely that their population will decline sharply. But this does not mean we should worry about the survival of brown leaf-nosed bats. For one thing, they are very small and eat very little food. And for another, their main diet consists of insects which are abundant in the forest. So even if fruit is scarce, these bats will probably survive. But there is another problem.
