THE SPARROW HAWK 
note, ‘“‘killy-killy-killy,” repeated in rapid 
succession. This beautiful and singularly col- 
ored little bird is quite plentiful in the northern 
part of the United States 
in summer, but at, the 
approach of winter many 
migrate to the Southern , 
States. 
This hawk usually 
nests in large wood- 
pecker holes, and con- 
sequently rears its brood 
quite close to the habita- | 
tion of man. The period Sparrow Hawk 
of incubation is about three weeks, and for several 
days after hatching the young are covered with a very 
soft down; in fact some of the down is not molted 
by the time the young birds are ready to fly.
