Feeding Behavioral Strategy of Rhinolophus pearsoni in Summer

Abstract: We used the Bat Sound Detector and the Professional Recorder to collect the echo of Rhinolophus pearsoni,and then analyzed the echoes by the software Cool Editor 2000.It showed that this bat species is a kind of FM/CF/CM bat,the echolocation calls comprise two constant frequency signals which two modulated frequency signals attached.The frequency of first CF signal is (61.08±0.019) kHz,the frequency of second CF signal is (60.97±0.03) kHz.After researched the foraging behavior of R.pearsoni in field,meanwhile,analyzed the food compositions by used Shannon-Weiner diversity index and Spearman correlation analyses,it suggested that this bat captured the mid sized insects of Lepidoptera and Coleoptera etc.by flycatching method mainly in evergreen and deciduous broadleaf forest in summer.This species of bats showed feeding selective to the types and body size of prey.Meanwhile,it suggested that there maybe relativity between the echolocation signals function and morphological feature of R.pearsoni.
