CATHARTIDiE — THE AMERICAN VULTURES. 493 



"Both in theii' mode of flight and in their movements upon the 

 ground this species differs materially from the Turkey Buzzard. 

 The latter walks steadily while on the ground, and when it mounts 

 does so by a single upward spring. The Black Vulture is ill at 

 ease on the ground, moves awkwardly, and when it essays to fly 

 upward takes several leaps in a shuffling side-long manner before 

 it can rise. Their flight is more labored, and is continued by flap- 

 ping several times, alternated with sailing a limited distance. Their 

 wings are held at right angles, and their feet protrude beyond their 

 tail-feathers. In all these respects the diiferences between the two 

 bu-ds are very noticeable, and plainly mark the species." (Brewer.)
