Fig. 3: Many individuals of both sexes switched between breeder and helper roles at least once in their lifetime.
From: A cryptic role for reciprocal helping in a cooperatively breeding bird
Bars (blue for males and red for females) show the proportion of individuals of each type that switched between helper and breeder roles across seasons at least once in their lifetime. For simplicity, switches to and from the role of non-breeder–non-helper are not shown. Error bars are 95% confidence intervals from an exact binomial test. To estimate switching probability for lifetimes, only individuals with records for complete lifetimes were included in this analysis.
