In the spring of 1885 the only record received on the migration of 
the Red-shouldered Hawk was a note of its arrival at Mount Carmel, 
Mo., April 5. In the fall of 1885 it appeared at Bonham, Tex., Novem- 
ber 23. Mr. Lloyd says it is a rare resident in western Texas. 
340. Buteo abbreviatus Caban. [440.] Zone-tailed Hawk. 
This southwestern Hawk is a fall visitant in Tom Green and Concho 
counties, Tex., where it was noted September 10, 1884 (Lloyd). In 
Comal county, Tex., it was found breeding in May, 1878, by Mr. W. H. 
Werner, who secured a male specimen and a set of eggs. Two pairs 
were observed (Brewster, Bull. Nutt. Ornith. Club, Vol. IV, 1879, p. 80). 
341. Buteo albicaudatus Vieill. [441.] White-tailed Hawk. 
A southwestern species, breeding along the Rio Grande in Texas 
(Sennett and Merrill), and occurring in western Texas in fall and win- 
ter (Lloyd). 
342. Buteo swainsoni Bonap. [442.] Swainson’s Hawk. 
Swainson’s Hawk is common in Manitoba and along the Red River of 
the North, and it occurs throughout most of the Mississippi Valley, and 
thence west to the Pacific. It remains in the West quite far north dur- 
ing cold weather, and is a common resident in western Kansas and 
western Texas. Even in eastern Texas, near Houston, it is “not un- 
common during the breeding season” (Nehrling). In 1884 a few were 
seen in January at Vermillion, Dak. It was not seen in Iowa until migra- 
tion commenced. About April 1 it appeared at Newton and Laporte 
City. 
In the spring of 1885 Swainson’s Hawk was recorded at Newton, 
Iowa, April 16, and March 23 at Laporte City, Iowa. A nest with 
three eggs was found May 13 at San Angelo, Tex. 
In the fall of 1885 the first south-bound migrant was seen at Emporia, 
Kans., October 10. 
343. Buteo latissimus (Wils.). [443.] Broad-winged Hawk. 
This is the only distinctively eastern Hawk occurring in the Missis- 
sippi Valley. It is found only rarely so far west as Kansas, the most 
westerly record being that of Dr. Watson, at Ellis, Kans. It breeds 
principally in the northern part of its range, being quite common in 
Minnesota (though it has been known to nest even in southern Texas), 
and in winter it passes south to Florida, and even to Central and South 
America. In spring migration in 1884 it passed through central Iowa 
about the middle of April, but only a few notes on it were reported. 
In the spring of 1885 the Broad-winged Hawk arrived at Mount Car- 
mel, Mo., March 23, at Laporte City, Iowa, March 30, and at Grinnell, 
Towa, April 17. In the fall of 1885 none were seen at Mount Carmel, 
Mo., after September 12,
