Fig. 5From: Evolution of body morphology and beak shape revealed by a morphometric analysis of 14 Paridae speciesIntraspecific covariation between morphological traits and altitude within P. major. Correlations of altitude with body weight, body length, culmen length and PC1 of body morphology are shown. Each dot represents an individual P. major specimen. Lines represent ordinary least square (OLS) regressionsBack to article page
