Echolocation Strategies of Aerial Insectivorous Bats and Their Influence on Prey Selection

  • Robert M. R. Barclay
Part of the NATO ASI Science book series (NSSA, volume 156)


There are few studies of prey selection by aerial insectivorous bats but Swift et al. (1985) noted that the available data suggests that large species feed selectively while small species are unselective. They suggested that large bats select prey, primarily on the basis of size, for reasons consistent with optimal foraging theory (i.e., to maximize the rate of net energy intake).
