Identifying little sandy desert bat species from their echolocation calls

Abstract

McKenzie NL and Bullen RD, 2003. Identifying Little Sandy Desert bat species from their echolocation calls. Australian Mammalogy 25: 73-80. In combination, the frequency maintained for the greatest number of cycles (FpeakC) and the width of this peak (quality factor) identified search-mode echolocation calls of nine species comprising the bat fauna of Australia's Little Sandy Desert. These data were derived from the frequency spectrum profile of frequency-divided calls. Differences between FpeakC quality factors of arid-zone emballonurid and molossid calls were functionally consistent with their different foraging strategies.
