The Nests of Two Hawks 
By JAMES N. LAYNE 
APRIL, 1942, found me prepared to study, photograph, and band a few 
hawks. I was not attempting to cover a large area or to do a great deal 
of recording, for although interested in birds of prey for several years this 
was the first time I had planned to really observe and study the wild hawks. 
My first experience with the “kings of the avian world” came through 
training them for falconry, and thus, as is the case with all conscientious 
falconers, I became intensely interested in the wild raptores and in their 
protection. 
Nest and eggs of red-shouldered hawk, April 22 
On April 17, at Highland Park, Illinois, I located two nests of red- 
shouldered hawks (Buteo lineatus) about three miles apart. The nests, 
fairly well constructed of sticks, were about 65 feet from the ground. The 
trunk of each nest tree was bare of branches to about 40 or 50 feet, and 
surrounding the base of the trees was, in both cases, a lush growth of poison 
ivy and a maze of tangled vines that rivaled the most cleverly constructed 
barbed wire entanglement.
