                    Figure 6-20 • Ventrodorsal views of the shoulder regions of a partridge (A) and an African Gray parrot (B) showing anatomical differences
                    in the appearance of the shoulder joints.

                    bones of a great blue heron are proportionately longer   able anatomical differences that exist between the
                    than those of a hawk. This is a perfectly predictable   shoulders of water birds and raptors (Figure 6-19) or
                    difference provided one has observed both birds (see   between parrots and partridges (Figure 6-20)? I dare
                    previous section). But who might predict the consider-  say quite few.
