Bird Song: Biological Themes and Variations
The study of bird song focuses on how song develops, sexual selection and female choice, and themes and variations in time and space.
Advances in the study of behavior
Advances in the Study of Behavior was initiated over 40 years ago to serve the increasing number of scientists engaged in the study of animal behavior. This volume makes another important
The different roles of social learning in vocal communication
It is found that unexpected genetic or environmental factors can have considerable effects on vocal behaviour in birds and mammals and are often more likely to cause changes or differences in vocalizations than investigators may assume.
Context-specific use suggests that bottlenose dolphin signature whistles are cohesion calls
Signature whistle copying was rare and did not initiate reunions or specific vocal responses, which strongly support the hypothesis that signature whistles are used to maintain group cohesion.
Bird song learning: causes and consequences
It is suggested that cultural evolution, geographical variation and dialect boundaries, being features of populations rather than individuals, are epiphenomena without functional significance in themselves, but song learning may confer advantages stemming from the copying process itself, in interactions with neighbours and in matching song to habitat.
Minimising Errors in Splitting Behaviour Into Bouts
Some problems in using log survivor functions to split behaviour into bouts are outlined. It is argued that it is usually best to choose that bout criterion which leads to the fewest within and
Why do the females of many bird species sing in the tropics
The two reasons that appear at present most likely to explain the greater prevalence of female song in the tropics are: the need for mutual stimulation to achieve breeding synchrony in a relatively aseasonal environment and sex role convergence arising from more long-term relationships and greater fidelity than is usual among north temperate species.
Individually distinctive pup vocalizations fail to prevent allo-suckling in grey seals
During the 1997 breeding season on the Isle of May, Scotland, vocalizations were recorded from grey seal, Halichoerus grypus, pups, and playback experiments revealed that mothers did not respond more to vocalizations of their own pups than to those of nonfilial pups.
