134 The Birds of Albany County 



Sharp-shinned Hawk. — Acdpiter velox. 11.30 



Common in Early Spring and Fall 



Field marks. — Tail square, barred; primaries barred; upper 

 parts grayish brown; under parts whitish, barred and 

 streaked with pale brown. 



This Hawk is the bitterest enemy of the small birds, 

 devouring more than any other of its race. It may possibly 

 breed here, though I have no record. The nest is placed 

 high in trees; eggs, four to six, nearly spherical, and wreathed, 

 generally around the center, with blotches of reddish-brown. 



Marsh Hawk. — Circus hudsonius. 19.00 



Uncommon Summer Resident 



Field marks. — Long tail, barred; upper tail-coverts white; 

 general color gray, darker on upper parts; breast and 

 under parts white, lightly barred with pale brown. 



This bird is apt to fly low and leisurely, and is therefore 

 easy to identify. The nest is placed on the ground in marshes ; 

 eggs, four to six, dull white.
