347a. Archibuteo lagopus sancti-johannis (Gmelin)—AMERICAN RovuGuH- 
LEGGED Hawk. 
A rather rare winter visitant in middle and southern Nebraska, 
but more common in the northern part of state. Breeds chiefly north 
of the United States. West Point, Omaha, Lincoln, Neligh, Cherry 
county. 
348. *Archibuteo ferrugineus (Lichtenstein) —-FERRUGINOUS ROUGH-LEG. 
This is the common rough-legged hawk in the state and occurs 
throughout. It is less common in the eastern portion, but becomes 
more plentiful as we approach the middle and western sections of the 
state. It nests in moderate numbers in the sand-hills, and com- 
monly along Pine ridge and about the buttes of western and north- 
western Nebraska. It is a ground bird to a great extent, and fre- 
quents the vicinity of prairie dog towns, upon the inhabitants of 
which it preys. 
349. *Aquila chryszetos (Linnaeus)—GoLpDEN EAGLe. 
This magnificent bird is found in moderate numbers throughout 
the state in winter, but is more common westward. Owing to its 
large size, fearless nature, and carrion-eating habits, we have numer- 
ous records of its occurrence each year, and a few still breed annually 
in Scott’s Bluff, Sioux, and Dawes counties. It bred quite generally 
over the state years ago. 
352. Halizetus leucocephalus (Linnaeus)—BauLp EAGLE. 
Much less common than the preceding, and seems to be confined 
chiefly to our larger water-courses even during its migrations. It 
probably formerly bred in the more heavily wooded portions of 
northeastern Nebraska, and it is likely that a few still do so, but 
there are no definite breeding records. It likes to nest near where the 
Osprey makes its summer home so as to have an opportunity to rob 
the latter of its catch and save the work for itself. Many records. 
[354. Falco rusticolus Linnaeus—Gray GYRFALCON. 
This northern falcon has been taken at Vermillion, S. Dak., and is 
known to wander casually south to Kansas. It is included here on 
the strength of a record of a single specimen seen by Bruner at West 
Point, but not positively identified; another, probably the same 
species, was reported to him as seen at Norfolk.] 
355. *Falco mexicanus Schlegel—Prairige Faucon. 
Over the entire state in migrations; rare in eastern portions, rather 
common westward; a few are resident, but the majority move south 
in late fall, and return in early spring. It is a regular breeder in 
Dawes and Sioux counties, where it nests during May and June 
upon ledges on the faces of perpendicular cliffs. 
356. Falco peregrinus anatum (Bonaparte)—Duck Hawk. 
A rare but regular migrant over the entire state. Lincoln, Omaha, 
West Point, Neligh, Dawes county. It probably breeds in this last
