Jamming avoidance response of big brown bats in target detection.
When searching for prey, big brown bats (Eptesicus fuscus) enhance the range of their sonar by concentrating more energy in the nearly constant-frequency (CF) tail portion of their frequency-modulated (FM) sweeps. We hypothesize that this portion of their signals may be vulnerable to interference from conspecifics using the same frequencies in their own emissions. To determine how bats modify t...
متن کاملSocial 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 کاملNovel Poxvirus in Big Brown Bats, Northwestern United States
A wildlife hospital and rehabilitation center in northwestern United States received several big brown bats with necrosuppurative osteomyelitis in multiple joints. Wing and joint tissues were positive by PCR for poxvirus. Thin-section electron microscopy showed poxvirus particles within A-type inclusions. Phylogenetic comparison supports establishment of a new genus of Poxviridae.
متن کاملMorphological, olfactory, and vocal development in big brown bats
Using a within subjects design, we documented morphological, bioacoustical and behavioral developmental changes in big brown bats. Eptesicus fuscus pups are born naked and blind but assume an adult-like appearance by post-natal day (PND) 45 and flight by PND 30. Adult females use spatial memory, acoustic and olfactory cues to reunite with offspring, but it is unclear if pups can recognize mater...
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...
