Social Calls Predict Foraging Success in Big Brown Bats
Animals foraging in the dark are engaged simultaneously in prey pursuit, collision avoidance, and interactions with conspecifics, making efficient nonvisual communication essential. A variety of birds and mammals emit food-associated calls that inform, attract, or repel conspecifics (e.g.,). Big brown bats (Eptesicus fuscus) are insectivorous aerial hawkers that may forage near conspecifics and...
متن کاملSocial calls of flying big brown bats (Eptesicus fuscus)
Vocalizations serving a variety of social functions have been reported in many bat species (Order Chiroptera). While echolocation by big brown bats (Eptesicus fuscus) has been the subject of extensive study, calls used by this species for communication have received comparatively little research attention. Here, we report on a rich repertoire of vocalizations produced by big brown bats in a lar...
متن کاملSocial calls coordinate foraging in greater spear-nosed bats
The function of social calls emitted by foraging bats has received little study. Here we use observations of free-ranging greater spear-nosed bats, Phyllostomus hastatus, and field playbacks to determine whether audible, broad-band 'screech' calls attract mates, warn conspecifics or influence access to food. Five lines of evidence suggest that screech calls enable adult females from the same ro...
متن کاملSocial Learning of a Novel Foraging Task by Big Brown Bats (Eptesicus fuscus).
Acquiring information via observation of others can be an efficient way to respond to changing situations or learn skills, particularly for inexperienced individuals. Many bat species are gregarious, yet few studies have investigated their capacity for learning from conspecifics. We tested whether big brown bats (Eptesicus fuscus) can learn a novel foraging task by interacting with knowledgeabl...
متن کاملSocial Vocalizations of Big Brown Bats Vary with Behavioral Context
Bats are among the most gregarious and vocal mammals, with some species demonstrating a diverse repertoire of syllables under a variety of behavioral contexts. Despite extensive characterization of big brown bat (Eptesicus fuscus) biosonar signals, there have been no detailed studies of adult social vocalizations. We recorded and analyzed social vocalizations and associated behaviors of captive...
