Genetic (A) and environmental (E) covariances (cov) and correlations (r) between song rate (BLUPs of song rate, in seconds1/2), beak colour (PC1), tarsus length (mm) and fitness (number of eggs fertilised/mean number of eggs fertilised). CovA and covE adds up to the phenotypic covariance, and likewise for the correlations.
