The effect of the number of eggs evicted by cuckoo nestlings (n = 20) on growth parameters within the evictor group for the nestling period.

Growth was estimated as deviations from growth patterns of evictor chicks randomly sampled in the study population (see Methods). Effect sizes (mean ± SE) refer to the regression coefficients for each model. Sample sizes for respective periods are given as number of measurements, and df refers to denominator degrees of freedom from the GLMM model controlling for chick identity and age.
