Young free—trailed bats, Tadarida brasiliensis mexicana, fall to the floor of nursey caves where they are eaten by beetles and predators. The number of young falling is correlated with the number of young in the cave and the bat's age. During the first two months of life there is a loss of 1.3% of the population. Ths mortality is lower than for the adults over a comparable period.
