With the exception of a few model species, individual differences in cognition remain
relatively unstudied in non-human animals. One intriguing possibility is that variation in …

There is increasing interest in individual differences in animal behaviour. Recent research
now suggests that an individual's behaviour, once considered to be plastic, may be more …

In species with mate choice, the choosy sex selects its mate based on traits that are thought
to indicate the mate's quality. In several bird species, females prefer males that sing more …

Mate choice studies routinely assume female preferences for indicators of high quality in
males but rarely consider developmental causes of within-population variation in mating …

Higher cognitive function depends on accurate detection and processing of subtle features
of sensory stimuli. Such precise computations require neural circuits to be modulated over …

Zebra finches are an important model for vocal learning and avian mate choice. The two are
contingent on each other: males' learned songs are addressed at females with learned …

Sex steroids have long been recognized for their dramatic impact on brain and behavior,
including rapid modulation of membrane excitability. It is a widely held perception that these …

To what extent do individuals assess the cognitive abilities of the opposite sex when
choosing a mate? With the exception of song learning in birds, the hypothesis that cognitive …

Vocal signals, including human speech and birdsong, are produced by complicated,
precisely coordinated body movements, whose execution is fitness-determining in resource …
