THE BIRDS OF WISCONSIN. 
65 
eastern part of Dane County by L. Kumlien. The nest was 
placed in a low bur oak, about eight feet from the ground, and 
contained three eggs, well incubated. This set was sent to 
Dr. Brewer. The female had been wounded, the primaries of 
one wing sticking straight up, even when the bird was sitting. 
She could make but short flights and this is in all probability 
the cause of the pair remaining here to breed, and it must be 
considered as an exceptional record. Extremely variable in 
plumage. 
Archibuteo f errugineits (Lichi.J. FERRlGIJfOUS ROUGH-LEG. 
On November 10, 1893, a pair of these hawks was procured 
by L. Kumlien at Lake Koshkonong. They were flying low 
over the rushes a short distance from shore, and one was 
secured with each barrel. October, 1894, another was taken 
at the same locality and came into our possession. We are 
positive of having seen the species in the western part of the 
state, but the above are the only records of capture obtainable 
for Wisconsin. These birds are preserved in the Kumlien 
collection. 
Aquiia chrysaetos (Linn.). GOLDEN EAGLE. 
Rather a rare bird in Wisconsin. Obtained principally 
from October to March, though there are several records for 
southern Wisconsin both earlier and later. During the past 
fifteen years we have handled about fifteen specimens taken at 
various localities throughout the state. Dr. Hoy records the 
nesting of this species in a large oak tree between Racine and 
Milwaukee in 1851, and had the egg in his collection some 
years ago. To us, however, the egg looked very similar to 
that of the bald eagle. This eagle is exceedingly variable in 
size. The Museum of Milton College contains perhaps the 
greatest extremes extant, one a gigantic female which fiercely 
attacked a man who was carrying a deer upon his back, in 
Chippewa County, the other, a male, less than thirty inches in 
length. During the winter the golden eagle resorts to any 
carcass of a dead horse or cow that has been left exposed and 
are then easily secured. We have the details of several 
instances where it has been suddenly surprised while feed- 
ing, and instead of retreating, as might be expected, has 
turned and fiercely attacked the intruder, sometimes with such 
vigor as to drive an unarmed man away.
