Identifying Little Sandy Desert bat species from their echolocation calls.

Abstract

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.
