Harris — Birds of the Kansas City Region. 263 



hawk far outnumbers its cousin the Red-tail, but this is not 

 true of this part of the state where the latter greatly pre- 

 dominates. 



The Red-shouldered Hawk is present during the entire year 

 but is never common. The dates of occurrence of migrants 

 are about the same as those of the Red-tail. 



A favorite resort for these birds is the wooded bluff regions 

 along the Missouri Valley. 



BuTBO swAiNSONi Bonaparte. Swainson's Hawk. 

 Occasional migrant. 



Swainson's Hawk but rarely straggles into the county and 

 then only during migration. 



Bankers has taken two specimens during recent years. A 

 pair have been found nesting about thirty miles southwest of 

 this county. 



We have very little additional data as to the local occurrence 

 of this hawk.

 Rather rare summer resident. 



The earliest record of the arrival of the Broad-winged Hawk 

 in spring is April 8, 1914. All other recorded dates are near 

 the end of the month. It, usually leaves late in October. 



It was found nesting near Independence in June, 1900 (Tin- 

 dall). A nest was located in the wooded bend of the Blue 

 River south of the rifle range in Swope Park in May, 1917. A 

 pair were disturbed while perched on an unfinished nest in a 

 tall tree in the timber near the mouth of the Blue in the 

 spring of 1914. This was an unusual place for these birds as 

 they prefer the upland woods to the bottom land. 



Aechibutbo lagopus sancti-johannis (Gmelin). Rough- 

 legged Hawk. 

 Fairly common winter visitant. 



The Rough-leg arrives from the north as early eis October 

 28 (1916), though more often a week or two later. It is not 

 often seen after March 12th (an exceptionally late date is 

 April 4, 1917). 



It may be looked for during winter, in any place in the
