Qualitative and quantitative roughness data of Branta canadensis. A Overview of bone textural patterns of the smallest (RMNH.AVES 259397), medium-sized (RMNH.AVES 259400) and largest (RMNH.AVES 259398) specimens. B Plot of longitudinally acquired Ra values and associated humerus size. The specimen numbers represent the ones in image A. Note the gradual decrease in Ra with larger size
