^^^ BIRD GALLERl. 



toes armed with strong curved claws. By means of these powerful 

 weapons they are able to seize and kill their prey and to tear up the 

 flesh. They are monogamous, and the female is generally larger than 

 the male. The eggs are few in number, and the young when hatched 

 are in a naked and helpless condition. 



Three families are recognised, the first including the Vultures 

 {VuHuridie), the second the Eagles and Hawks {Falconidai) , and the 

 third the Ospreys [Pandionidm) . 



Family I. VulturidyE. Vultures. 



[Oases These Birds of Prey inhabit the tropical and subtropical portions of 

 4o, 46, j.jjg Qj^ Worldj where they represent the Turkey Vultures [Cathartidm)

 case.] latter birds in many important particulars, but in their habits they are 

 very similar. They feed chiefly on the carcases of dead animals which 

 their keen sight enables them to discover, and though many naturalists 

 have maintained that it is chiefly by the sense of smell that they find 

 their prey, there can be no doubt that this is a mistake, as has been 

 proved by experiments. Their claws being short and rather blunt, 

 Vultures rarely attack and kill living animals ; they are cowardly 

 sluggish birds, endowed with extraordinary powers of flight, 

 [Case 45.] The Cinereous or Black Vulture (F. monachus) (829), ranging from 

 Southern Europe to China, is the only representative of the genus 

 Vultur. It is rather solitary iu its habits, breeding singly in trees and

 adjoining centre Case. This southern European species is one of the 

 most familiar, and is specially numerous in Spain, where it breeds 

 [Case 45,] in caves iu the perpendicular crags of the Sierras. Another represen- 

 tative of the genus is the Himalayan Grifi'on- Vulture (G. himalayensis) 

 (831), and a closely allied form the White-headed Vulture {Lophogyps 

 [Case 40.] occipitalis) (832) will be found on the floor of the next Case together 

 with the Sociable or Eared Vulture [Otogyps auricularis) (833) and the 

 Egyptian Vulture {Neophron percnopterus) (834), which has on more 

 than one occasion wandered to Great Britain.

 (Plates XV., XVI., XXIV.) 



[Case 40.] Almost all the remaining Birds of Prey are included in this family, 

 and are divided into six subfamilies, the Caracaras {Polyborinai), the 

 Long-legged Hawks {Accipiirin<E) , the Buzzards {Buteonince) , the 

 Bearded Vultures (Gypaelinee) , the Eagles {A quilince), and the Falcons
