Accidentally to New England. Winters from Texas southward 

 and migrates sometimes in large flocks. 



The Swainson's Hawk was reported by Mr. H. Nehrling as a 

 rare breeder in the region of Pierce City, Lawrence Co., in the 

 early eighties. The writer saw it in Platte Co., opposite Leaven- 

 worth, June 28, 1906, a time of the year when a well-bred Swain- 

 son's Hawk should be on its breeding grounds. In Osprey, 

 Vol. 5, p. 109, we read: "On April 23, 1901, a pair was found 

 building a nest in an elm that grew on the west bank of Sugar 

 Creek, Linn Co., Kansas." This is only 28 miles from our state 

 line. In has repeatedly been found nesting in central Iowa, 

 and once in southeastern Illinois (Richland Co., 1875) by Mr. 

 E. W. Nelson. In his migration reports to the Department of 

 Agriculture, Mr. W. G. Savage reports this species from Jasper 

 Co., October 12 and 16, 1902, and from Shannon Co., September 

 15 to 24, 1903. Mr. Chas. K. Worthen has taken it at Warsaw, 

 111., and further observations will probably show that it is a not 

 uncommon transient visitant, especially westward, and a pos- 

 sible breeder in the northwestern counties. 



*343. Buteo platypterus (Vieill.). Broad-winged Hawk. 



Buteo pennsylvanicus. Buteo latissimus. Astur pennsylvanicus. 



Geog. Dist. — From northern South America, Mexico and West 

 Indies through Eastern United States to New Brunswick, On- 

 tario and eastern Manitoba. West to Minnesota, eastern Ne- 

 braska, Kansas and Texas. Breeds throughout its North Ameri- 

 can range and winters from the South Atlantic and Gulf States 

 southward. 



The Broad-wing is a fairly common summer resident in Mis- 

 souri, mainly eastward, less commonly westward. It prefers 

 undulating ground where wooded tracts, even of medium-sized 

 trees, adjoin creek bottoms, wet meadows and cultivated fields. 

 Such localities still exist in spite of the universal devastation of 

 timber, in most parts of the state. It seems to shun the swampy 

 southeast and the bottoms of the large rivers as well as the 

 dry ridges of the Ozarks and the drier stretches of the prairie 

 region. None winter with us; migration from the north is brisk 

 during the fourth week of September, when on some days dozens 

 may be seen sailing over in loose flocks. It does not stop over 

 as long as the Red-tail and Red-shoulder, but small parties may 

 be met with during the first half of October, after which the
