 | | The New World vultures, family Cathartidae, are superficially similar to large birds of prey, but are probably more closely related to storks, with which they share some anatomical and behavioral features. |
 | | The American vultures also differ from the Old World group in that they have longitudinal, perforated nostrils without a partition and lack a voice, due to the absence of a syrinx. |
 | | Within the mixed-species flocks seen at lion kills in Africa, there is a definite hierarchy, with smaller species, such as the Egyptian vulture, Neophron percnopterus, having to wait until the more powerful species, such as Rüpell’s griffon, Gyps ruepellii, are finished. |
