Mate-switching is not associated with offspring fitness in a socially monogamous bird | Proceedings of the Royal Society B: Biological Sciences
In many species, individuals form socially monogamous pair-bonds lasting multiple
breeding seasons, or even whole lifetimes. Studies often suggest social monogamy to
be adaptive, but this is usually q...

Then, we studied divorcing using long-term data of @seychelleswarbler.bsky.social addressing all these shortcomings, and found that divorce is related to male age, pair-bond tenure, and reproductive success, but that there are no strong fitness consequences to divorce

We addressed 5 shortcomings: (1) divorcees and widows and (2) initiators and victims of divorce are not disentangled, (3) consequences of divorce and widowhood are not studied together (4) long-term consequences and (5) age-dependency of divorce are not addressed
