ANOVA table and estimated coefficients – linear mixed model for nestling morphological traits.

Wing and tarsus models are repeated measures models with Nest of Origin and nestling ID as random factors. Hatching date and brood size are centred for ease of interpretation. F and p values stem from ANOVA table, and for non-significant interactions represent values just before removal (significance level for removal of interaction p>0.1). Reference = 8 days old female nestling from a prenatal maternal control and matching environment group. SE = standard error.
