Pectoralis muscle mass is the combined mass of the pectoralis major and the supracoracoideus. Data on heart, muscle and body mass were collected within 30 min from birds that had been killed or that had died inadvertently during mist net collection.

Masses were measured to within 0.001 g using an Acculab digital scale(model no. PP-2060D).

Sample sizes from Hartman(1961) were different for each of the morphological variables.
