Variation in personality and behavioural plasticity across four populations of the great tit Parus major

1.Interest in the evolutionary origin and maintenance of individual behavioural variation and behavioural plasticity has increased in recent years. 2.Consistent individual behavioural differences imply limited behavioural plasticity, but the proximate causes and wider consequences of this potential constraint remain poorly understood. To date, few attempts have been made to explore whether individual variation in behavioural plasticity exists, either within or between populations. 3.We assayed 'exploration behaviour' among wild-caught individual great tits Parus major when exposed to a novel e...
