Harris—Birds of the Kansas City Region. 268 
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. 
BuTEO SWAINSONI Bonaparte. Swainson’s Hawk. 
Occasional migrant. 
Swainson’s Hawk but rarely straggles into the county and 
then only during migration. 
Dankers 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. 
BuTEO PLATYPTERUS (Vieillot). Broad-winged 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. 
ARCHIBUTEO LAGOPUS SANCTI-JOHANNIS (Gmelin). Rough- 
legged Hawk. 
Fairly common winter visitant. 
The Rough-leg arrives from the north as early as 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
