The benefits of stable pair bonds (that persist between breeding attempts)
have been well described, but are relatively less well known in
cooperatively breeding species. If pair bonds are beneficial, then it is
possible that the bond between the behaviorally and socially dominant pair
may influence factors such as reproductive success and group stability in
cooperative species. Here we used long-term data to investigate the
relationships between pair bond tenure, reproductive success and group
stability in the cooperatively breeding pied babbler (Turdoides bicolor).
Pair bond tenure positively influenced both the number of offspring
recruited annually per pair, and total reproductive success (over entire
pair bond duration), indicating that pair bond tenure has an important
influence on reproductive success. The likelihood of immigration into the
group was lower for groups containing a bonded pair with long tenure,
indicating that the duration of pair bonds may impact group stability.
These findings suggest that pair tenure, a hitherto relatively unexplored
factor in cooperative species, may have an important influence on group
dynamics.
