Abstract
Different approaches to echolocation in the Microchiroptera, as reflected by differences in call design (frequency, patterns of change of frequency over time), raise an important question, namely can we equate specific call designs with particular foraging strategies? It is difficult to answer the question now because we do not have data on individual variation either in call designs or in foraging strategies. In some species, echolocation calls vary in design (e.g., Rhinopoma hardwickei, Lasiurus cinereus, and some neotropical emballonurids — Habersetzer 1981; Belwood and Fullard 1984; Barclay 1983, respectively), while in others there is no evidence of variation (e.g., Myotis myotis — Neuweiler 1983).
