In the spring of 1SS1 it was reported from various parts of Iowa, 

 about the middle of March; from Lanesboro, Minn., March 2 (two 

 being seen during a furious storm, and it was repeatedly seen the next 

 week). April 3 it appeared at Two Eivers, Manitoba (latitude 49° 28') ; 

 and April 12 it reached Oak Point, Manitoba. 



In the spring of 1885 the Eed-tailed Hawk was seen at Laporte City, 

 Iowa, March 3, and at Lake City, Minn., March 26. Various irregular 

 notes were given from intervening places. 



In the fall of 1885 the first returning migrants reached Bonham, 

 Tex., November 10, and were common there November 19. 



337a. Buteo borealis kriderii Hoopes. [436a.] Kriders Hawlc. 



An inhabitant of the Great Plains, the eastern limit of its range cover- 

 ing the western part of the Mississippi Yalley from Minnesota to Texas. 

 Has been taken in Minnesota, Wisconsin, Iowa, northeastern Illinois, 

 Kansas, and Texas. Eoberts and Benner took a young Krider's Hawk 

 from the nest in western Minnesota in June, 1879, and Mr. Eidgway 

 tells me he has examined two females shot from the nest in Minnesota. 



337b. Buteo borealis calurus (Cass.). [43G6.] Western Bed-tail. 



The Western Eed-tail reaches the western border of the Mississippi 

 Yalley district. Colonel Goss records it as not uncommon in Kansas in 

 winter. It has been taken also in Illinois, near Chicago (Xelson). The 

 only observer who has had the good fortune to secure it is Mr. Lloyd, 

 who finds it an abundant resident in Concho county, Tex., where it 

 breeds from April 22 to May 22. 



338. Buteo harlani (Aud.). [433.] Harlan's Hawk. 



Harlan's Hawk is an inhabitant of the Gulf States and the lower 

 Mississippi Yalley, and has been found as far north as Kansas, Illinois, 

 and Iowa. It was reported by one of the observers in former years 

 from Liter, 111., aud has also been found at Warsaw, 111., and at Gaines- 

 ville, Tex. Nothing is known of its movements and breeding habits. 

 The species was described by Audubon from a specimen killed in 

 Louisiana. 



339. Buteo lineatus (Gmel.). [439.] Iied-sliouldered Haiclc. 



The movements of this species are similar to those of the Eed-tailed 

 Hawk, with which it is often found during migration, but it does not 

 go so far north, seldom passing beyond our northern boundary. In 

 eastern Kansas it is a common resident (Goss). Both it and the 

 Eed-tail intended to spend the winter of 1883-'81, as usual, in the 

 vicinity of Saint Louis, but the severe cold of the first week in January 

 proved too much for them, and they migrated, to return with the first 

 warm wave the last of the month. It was reported as wintering at 

 Chicago, and as a rare winter resident in southern Missouri. It mi- 

 grated at the same time as the Eed-tail, and at Elk Eiver, Minn., where 

 the latter was not seen, it arrived March 21.
