Information transfer at evening bat colonies
Article Abstract:
The prey density, following behavior, spatial and temporal association among foraging flights and foraging success of evening bats were quantified to analyze information transfer. Observations of Nycticeius humeralis in northern Missouri showed that juvenile and some adult bats follow adult females to their roosting and feeding sites based on information exchange among nursery colony members. Roost exclusion experiment showed that bat vocalizations may be either active information exchange or alarm calls to facilitate group departures.

Greater spear-nosed bats discriminate group mates by vocalizations
Article Abstract:
Female greater spear-nosed bats, Phyllostomus hastatus, can discriminate the calls of members of their own social groups but fail to discriminate individual calls based on field and laboratory playback studies using bat populations from three caves. The familiarity and discrimination of groupmates provide benefits to these bats in terms of sharing food resources and guarding feeding areas.

Function of male song in the greater white-lined bat, Saccopteryx bilineata
Article Abstract:
The male vocalizations of greater white-lines bats, Saccopteryx bilineata, were recorded on the Island of Trinidad and some behavioral observations of the focal male and nearby bats were made at the time the calls were given. The results show that the different call functions may have different functions in S. bilineata.
