How much to invest in parental care and by who remain puzzling questions
fomented by a sexual conflict between parents. Negotiation that
facilitates coordinated parental behaviour may be key to ease this costly
conflict. However, understanding cooperation requires that the temporal
and sex-specific variation in parental care, as well as its multivariate
nature is considered. Using a biparental bird species and repeated
sampling of behavioural activities throughout a major part of
reproduction, we show a clear division of tasks between males and females
in provisioning, brooding and foraging. Such behavioural specializations
fade with increasing nestling age, which stimulates the degree of
alternated feeding visits, as a recently promoted form of conditional
cooperation. However, such cooperation is thought to benefit offspring
development, which is not supported by our data. Thus, from a proximate
point of view, conditional cooperation via alternation critically depends
on the division of parental tasks, while the ultimate benefits have yet to
be shown.
