Repeatability of parental effort in male and female Pied Flycatchers as measured with doubly labeled water

Abstract: Intensity of parental care is one of the critical factors affecting offspring growth and final size and thus is a key variable in life-history evolution. In the study population of Pied Flycatchers (Ficedula hypoleuca), it was previously shown that maternal daily energy expenditure was an important source of variance in offspring size and likelihood of infection by blood parasites. Thus, energy expenditure may be considered a parental-performance effect, and variation among females in the intensity of parental… Show more

“…during both observations and are experiencing similar environments. For example, we might expect reproductive effort in birds to be more repeatable within broods rather than across seasons (Potti et al 1999; Moreno et al 2002). In contrast, when the interval between observations is long, there is more opportunity for developmental change; individuals are more likely to undergo dramatic change such as sexual maturity or a niche shift over a longer period of time.…”

“…Consequently, nest defence behaviour in birds should be more repeatable within the same breeding attempt or between different attempts within the same breeding season than between different seasons (Potti et al. ; Samaš et al. ).…”
