The morphological development of the locomotor and cardiac muscles of the migratory barnacle goose ( Branta Leucopsis)
The masses of the locomotor and acardiac muscles of wild barncale goose gollings, from migratory population, were examined systematically during development and their values compared to those of pre‐migratory geese. Pre‐flight development was typified by approximately linear increases of body, leg,...
