6 Birds of Canada. 
Sub-Family MILVIN &.— The Kites. 
Circus hudsonius—The Marsh Hawk. 
The Marsh Hawk is one of our most common 
summer hawks. It arrives here from the south 
about the first of May. Color, bluish-cinereous 
above; beneath, reddish-white. Nests, on the 
ground ; eggs, four or five, of a dirty white color. 
Feeds upon field mice, principally, and the num- 
ber of these destructive little animals which it 
devours during the breeding season is almost 
incredible. It is consequently entitled to the 
protection of the farmer. 
Sub-Family AQUILINE.—The Eagles. 
Halietus leucocephalus—The White-headed 
Eagle. 
This noble bird is frequently met with on the 
high shore of Lake Ontario throughout the year, 
and is often seen in the Ottawa region, near the 
interior lakes, and in the vicinity of the Rideau 
canal. Feeds upon wild fowl and small animals, 
and is equally partial to fish. The nest of this 
species, formed of large sticks, sods, moss, and 
hay, is usually found in a lofty tree, in a swamp 
or morass, and, as it is increased or repaired 
every season, becomes of great size ; eggs, two 
or three, of a yellowish-white color, with brown 
patches. General color, brownish-black; head 
and tail, white ; bill, feet, and iris, yellow.
