P was estimated from a multivariate model with no random effects while individual identification and nest were then included to decompose the covariance matrix into G, N and R. Values below the diagonals are covariances (with SE) and values above the diagonals are the corresponding correlations. Bold values denote nominally significant parameter at P <0.05 based |estimate| ≥2SE.
