The distal tip of the prenasal process is directed ventrally. The lower jaw extends only as far as the anterior margin of the orbit.

Journal of Anatomy, EarlyView.New World vultures are the only avian clade proposed to lack a syrinx and have been described as non‐vocal. Using dissection, diceCT, and histology, we demonstrate that cathartid vultures have novel syringeal features that form a syrinx and vocal characterization reveals that they produce more complex vocalizations than previously reported.
