Abstract
⺠We examined personality and behavioural plasticity in tree swallows, Tachycineta bicolor. ⺠Differences in personality between individuals explained approximately 55% of variation in aggressiveness. ⺠More aggressive individuals were better able to respond to variation in ambient temperature and tended to fledge more young. ⺠However, plasticity conferred a reproductive advantage only for nonaggressive males. ⺠Our results suggest that personality and plasticity are context-dependent components of fitness in tree swallows.
