 somewhat resemble small l^^agles in tlicir tliglit aud liabits, ])rcyiug 

 on the smaller mammals such as rabbits, rats, and mice, as well as 

 reptiles aud insects. They do not capture their prey on the wing, aud 

 consequently seldom kill birds except young ])Oultry. Tliey must be 

 regarded as useful birds to both farmer aud agriculturist. A very 

 hand.some species is the Red-backed Buzzard (B. erythronotus) (870) 



[Case 48. from S. America. The Common Buzzard [B. buteo) (875) is still fairly 

 numerous in various parts of Great Britain. As will be seen from the 

 specimens exhil)itedon the lowest shelf of the Case, the plumage varies 

 greativ, some old bii'ds being almost uniform dark brown above and 

 below. A large South American form will be found in the Giant 

 Buzzard [Gtranoaetus melanoleiiciis) (876). 



[Case 48. Next come the Buzzard-Hawks of America represented by several 

 genera, 7J«/eo/rt (877), Astunna (878), and Rupornis (879), and the very 

 handsome black-and-white species such as the Wliite-spotted lluzzard 

 (Leiicop/enus- inehinnps) (881). 



Tlie Harpies include five very large powerful species placed in four 

 genera, all of which are represented in the Case. The Crowned Ilarpy 

 (Har/ii/lialiaetus coronatm) (884), the Guiana Crested Harpy [Morphnm 

 (/ulanemis) (885), and the true Harpy (Tlirasaotiis hnrpijia) (886) are 

 all long-crested forms from South and Central America ; and the latter, 

 whose range extends into Mexico and Texas (where the species is locally 

 known as the " Lobo volante " or " Winged Wolf "), is one of the most 

 splendid as well as the most powerful of all tlie Birds of Prey. It feeds 

 chiefly on mammals, including fawns, monkeys, foxes, and moderate 

 sized pigs. An allied form, Harpyopsis nov(e-ffui?iete (887), found in 

 New Guinea, has the general ajtpearaucc of a great (ioshawk and is 

 said to prey on Tree-Wallabies. 



[Ga.se 48.] The Bearded Vultures or Lajmmergeicrs (888) form the next sub- 

 family Gijpa'etiiue , wdiich includes two very large species, one found 

 from South Europe to the Himalayas and the other in Africa. 

 They arc much like Vultures in their habits but not such foul feeders. 

 Like the Egyptian Vultures (Neophron) they are said to obtain the 

 marrow from bones by carrying them up into the air and letting them 

 fall from a great height, and land-tortoises are similarly treated. Hence 

 the name " Bone-breaker " by which they are often known. Their flight 

 is grand in the extreme, but the stories of their having carried off children 

 are highly improbable, for in spite of their spread of wing they lack 

 the strength of foot to do so.
