Figure A1.

Female social networks (five nearest neighbours) in Wytham's great tit population during the breeding season. A representative network for Wytham is depicted (2006), along with the Marley networks for each year (2005–2010). Coloured nodes denote individuals with a personality score and open circles mark nestboxes occupied in that year but where the female's personality is unknown. Black lines denote a two-way association (both each other's nearest neighbours), whereas grey arrows depict the direction of one-way associations. For these directed networks, 70–80% of all links are reciprocal.
