Sonar signals of big brown bats, Eptesicus fuscus, contain information about individual identity, age and family affiliation
Article Abstract:
The big brown bat, Eptesicus fuscus, emits echolocation (signal) signals which transmit messages about individual identity, family membership, sex and age. Each individual has distinct emissions but there are similarities among the emissions sent by the different members of a family. The emissions of the adults and young bats vary but there are no differences of emissions between the male and female children. The sonar signals of mothers and children in a family are equally arranged in the cross-correlation space. The signal similarity within a family is possibly due to heredity and learning.

Female big brown bats, Eptesicus fuscus, recognize sex from a caller's echolocation signals
Article Abstract:
The identification of the sex of an unfamiliar bat from playbacks of its echolocation calls by the female big brown bats is examined. The results suggest that the female big brown bats are capable of determining the sex of an unfamiliar bat from its echolocation calls.
