346. Asturina plagiata Schlegel. [445.] Mexican Goshawk. 
The Mexican Goshawk occurs regularly as far north as the southern 
border of the United States, and occasionally up the Mississippi Valley 
to southern Illinois. 
347a. Archibuteo lagopus sancti-johannis (Gmel.). [447.] American Rough-legged 
Hawk, 
The whole army of these Hawks crosses our northern boundary twice 
ayear. During the winter they are distributed over most of the Missis- 
sippi Valley, the exceptions being the extreme northern and extreme 
southern portions. They are most numerous in the middle sections, 
thinning out each way. At Elk River, Minn., all had passed south by 
December 24, 1883. A little south of this point they remained all 
winter. At Vermillion, Dak., ten were seen during a day’s tramp in 
January, 1884, At Mount Carmel, Mo., they were quite common all win- 
ter on the prairies, the bulk leaving March 10, and the last on the 24th. 
In the fall of 1884 the first Rough-legged Hawk was seen at Mount 
Carmel, Mo., November 7. It used to be abundant there during the 
winter, but now is somewhat rare. 
In the spring of 1885 the Jast was seen at Mount Carmel March 15. 
The first appeared at Oak Point, Manitoba, April 7, and they were 
common there April 10. In the fall of 1885 they returned to Mount 
Carmel November 10; the next was seen November 12, and by Novem- 
ber 20 they were in usual winter numbers. 
348. Archibuteo ferrugineus (Licht.). [448.] Ferruginous Rough-leg; Ferruginous 
Buzzard. 
Chiefly a western species, a few coming east into the Mississippi 
Valley. It is resident in western Kansas, where Dr. Watson says it is 
tolerably common at Ellisevery year. It has also been seen in western 
Nebraska, and is abundant in western Texas in winter. It has been 
seen once at Rock Island, Ill, and has been found nesting at Vermil- 
lion, Dak., and Grinnell, Iowa. 
Mr. Balmer writes from Paris, Ill.: “‘OnJanuary 19, 1886, I had the 
good fortune to capture what I consider a rare bird for this State, viz, 
Archibuteo ferrugineus. He seems to have got along way out of his lati- 
tude. Hecame with a thaw, in a south wind, after our big, big blizzard. 
I shot him out of a tree after dark, having marked him down for the 
night. The bird is a male, and measured 53 inches in extent.” 
349. Aquila chrysaétos (Linn.). [449.] Golden Kagle. 
In the western mountains this species comes far south in winter, even 
to New Mexico and Arizona, but nearer the Mississippi it comes only 
to Kansas. Some years ago one was taken in November at Fayette, in 
central Missouri, but it is very rare so far south. Several were seen 
and some captured in central and northern Iowa in the winter of 
188384, the last ones leaving from March 15 to 22. Most Golden
