RED-SHOULDERED- BUZZARD. 
I have had the tree on which the nest was placed cut down, I have observed 
the same pair, a few days after, build another nest on a tree not far distant 
from the spot in which the first one had been. 
The mutual attachment of the male and the female continues during life. 
They usually hunt in pairs during the whole year ; and although they build 
a new nest every spring, they are fond of resorting to the same parts of the 
woods for that purpose. T knew the pair represented in the Plate for three 
years, and saw their nest each spring placed within a few hundred yards of 
the spot in which that of the preceding year was. 
The young remain in the nest until fully fledged, and are fed by the 
parents for several weeks after they have taken to wing, but leave them and 
begin to shift for themselves in about a month, when they disperse and hunt 
separately until the approach of the succeeding spring, at which time they 
pair. The young birds acquire the rusty reddish colour of the feathers on 
the breast and shoulders before they leave the nest. It deepens gradually at 
the approach of autumn, and by the first spring they completely resemble the 
old birds. Only one brood is raised each season. Scarcely any difference of 
size exists between the sexes, the female being merely a little stouter. 
This Hawk seldom attacks any kind of poultry, and yet frequently pounces 
on Partridges, Doves, or Wild Pigeons, as well as Red-winged Starlings, and 
now and then very young rabbits. On one or two occasions I have seen 
them make their appearance at the report of my gun, and try to rob me of 
some Blue-winged Teals shot in small ponds. I have never seen them chase 
any other small birds than those mentioned, or quadrupeds of smaller size 
than the cotton rat ; nor am I aware of their eating frogs, which are the 
common food of the Winter Falcon.
