Variation in nestling body mass (brood means) in relation to female (A) body mass and (B) brood size as nestlings, and in relation to females’ current (C) body mass and (D) territory quality as breeding adults. In (C), female body mass is depicted for graphing purposes only; female body condition as an adult was included as the independent variable in this analysis, but her body mass as a nestling (B) was used in analyses as our morphological data for females at that age were incomplete. Values on x-axes are z-scores
