  1. Effects of experimental clutch size reduction (treatment), relatedness between dominant and subordinate female (Kinship), and the interaction of these two fixed factors on alloparental brood care by the subordinate female. Female body size and clutch size were included as covariates. Depicted are results of a GEE model, with female identifier as subjects (N=16 females, n=42 clutches sampled).
