Members of the family Phaneropteridae are well known for their acoustical duetting behaviour, used for locating and meeting a mate. In Poecilimon affinis, typically the male approaches a responding female phonotactically. A set of behavioural experim

Defense of territories in many animal species involves the advertisement of territory holder quality by acoustic signaling. In the sac-winged bat Saccopteryx bilineata, males engage in territorial countersinging when reoccupying their day-roost terri

Vocal group signatures facilitate group cohesion or the exclusion of nongroup members and thus greatly affect the social system of any given species. This is especially significant for highly mobile animals such as bats. The greater sac-winged bat, S

We recorded social vocalizations from two sympatric species of glossophagine bats, Glossophaga soricina and G. commissarisi, using habituated captive groups that were housed in separate flight cages. Whenever possible, the species-specific vocalizati

In males of the grasshopper Chorthippus biguttulus the relationship between song and mating success was investigated in three isolated field populations of individually marked animals within their natural habitat. In a population with muted males (fo

Summary In mammals, adult behaviour patterns are often expressed by juveniles throughout ontogeny. In bats, many social behaviours develop before pups are weaned, but the ontogeny of social behaviours in juvenile bats is largely unexplored. We studie

Most bat species inhabit roosting sites in whichthey are well concealed during the day, such ascaves or tree holes, whereas others roost in exposedlocations on tree trunks or branches (Kunz and Lum -sden, 2003). For the latter, it is essential to app

Like many other mammals, Saccopteryx bilineata exhibits a polygynous mating system, in which each male defends a group of females called a harem. Colonies consist of several harems, and nonharem males roost adjacent to harems. Unlike most other mamma

In many animal species, individuals compete for resources but avoid escalated conflicts by threat displays, i.e. a mutual signalling behaviour that enables the opponents to predict the outcome of the conflict without the necessity of actual fighting.

We investigated the acoustical component of the recognition process leading to successful mother–pup reunions in the greater sac-winged bat, Saccopteryx bilineata , using both a statistical approach and playback experiments. Statistical evidence fo
