33Q. RED-SHOULDERED HAWK. 

 lineatus lineatus. 



Buteo 



Red-shouldered Hawk 



Range. North America, east of the Plains 



and from the southern parts of the British 



Provinces southward; abundant and breeding 



throughout its range. 

 This species is smaller than the Red-tailed 



and is not as powerfully built; length 19 inches. 



The adults are handsomely barred beneath 



with reddish brown, giving the entire 

 underparts a ruddy color. Like the 

 last species, they rarely feed upon 

 poultry, confining their diet chiefly to 

 mice, rats, frogs, reptiles, etc. These 

 Hawks nest in the larger growths of 

 timber, usually building their nests 

 high above the ground. The nest is 

 of sticks, and lined with leaves, weeds 

 and pieces of bark. They lay three 

 or four eggs with a white ground 

 color, variously blotched and spotted, 

 either sparingly or heavily, with dif- 

 ferent shades of brown. Size 2.15 x 

 1.75. Data. Kalamazoo, Michigan, 

 April 25, 1898. Nest about 40 feet up 

 in an oak tree; made of sticks and 

 twigs and lined with bark. Four eggs.

339a. FLORIDA RED-SHOULDERED HAWK. Buteo lineatus alleni. 



Range. Florida and the Gulf coast; north to South Carolina. The nesting 

 habits of this paler sub-species are precisely like those of the last species.
