The hawks and eagles (Falcon' idee) (Fig. 240) comprise about three hun- 

 dred and fifty species and include such birds as the kites, hawks, buzzards, 

 and the osprey or fish-hawk. These are almost exclusively carnivorous. 

 Raptores are easily distinguished by their hooked bills and sharp talons. 

 They feed chiefly on rats and mice. Occasionally some of the hawks will 

 attack chickens, but there are more friends than foes among them. Hawks 

 build large nests of sticks in tall trees. They lay four whitish eggs with 

 brown blotches.
