Figure 6-13 • Ventrodorsal projection of the partially folded wings of a great blue heron shows the relative difference in length between the
humerus and radius/ulna. Note the heron’s long, narrow wing bones and laterally compressed torso compared to a raptor.
Figure 6-14 • Close-up, ventrodorsal view of the cubital joint of a Boreal owl. Unintended rotation of the humeral joint has resulted in some
secondary obliquity of the elbow—a technique that can be used to deliberately separate the humeroulnar and humeroradial joints from one
another to improve their visibility.
