"We predicted that bolder birds would have higher reproductive success but that pairs with greater dissimilarity in their personalities would have lower reproductive success (Biro & Stamps, 2008; Munson et al., 2020). We also predicted that the probability of re-pairing would increase following breeding failure (Coulson, 1966; Mercier et al., 2021). As a result, we predicted that pairs with greater dissimilarity in personality would be more likely to re-pair. Although individuals that fail to breed may benefit from re-pairing in the long term, we predicted this behaviour to cause an initial decline in reproductive success for re-pairing birds compared to faithful couples (Ismar et al., 2010). We predicted that birds would assortatively mate by boldness and that re-pairing birds would choose a new partner more similar to them in boldness than their previous mate (Collins et al., 2019). Finally, we also predicted that shy birds would be more willing to change their breeding strategy following reproductive failure compared to bolder conspecifics, leading to higher re-pairing probabilities (Wolf et al., 2008)."
