BIRDS OF ONTARIO. 



39 



SUBFAMILY ACCIPITRIN^E. (KITES, HAWKS, EAGLES, ETC.) 

 GENUS ELANOIDES. 



(327) Swallow-tailed Kite. 



(Elanoides forficatus.) 



Mr. Mcllwraith records the occurrence of this species in western 

 Ontario and also at Ottawa, and it is quite likely to be seen here again, 

 as it is a great wanderer. 





Marsh Hawk. 



GENUS CIRCUS. 

 (331) Marsh Hawk. 



(Circus hudsonius.) 



Very common summer resident, breeding in secluded marshy places 

 throughout the Province. Arrives early in April, departs about the end 

 of October. One of our most useful Hawks, feeding principally upon the 

 destructive meadow mouse. This Hawk may readily be distinguished 

 from all others by its low skimming flight, as it works over the meadows 

 in search of its favorite food, and also by the white patch at the base of 

 its tail, which is very conspicuous. A heavy penalty should be inflicted 

 on persons who destroy these birds.
