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

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