1880. 
Middlesex County, Mass. 
Visited the nest found in Belmont. May 5. As we 
approached it the female started off and made away 
throng the pines like a bullet. I concealed myself 
behind the trunk of a large tree and av/aited her return. 
The v/oods were very lovely and peaceful v/ith the after¬ 
noon light streaming through the gauzy maples and floodiig 
the openings botv/oon the pines. Black-throated Green 
Warblers sang in the evergreens, a Flicker made the ma¬ 
ples ring \7ith his quavering laugh, and occasionally an 
Oven bird mounted skyv/ard and uttered his rich evening 
song. Once a Black—throated Blue Warbler came overhead 
hopping along the stem of a grape vine that festooned an 
ancient willovr. At length after about fifteen minutes, 
the Hawk appeared gliding through the pines ’vith set 
wings and alighting in the top of a tall red maple. I 
sat perfectlj^ still, and after the lapse of a few min¬ 
utes she started directly for the nest. As she passed 
me I gave her both barrels bring her down with the second. 
Shortly afterwards the male came into the sv/amp but ho 
was so shy that I failed to get a shot at him. Ho floe 
only a few rods at a time swooping down almost to the 
ground, and pitching abruptly upv/ard to some lovr branch. 
Ho frequently jerked his tail and uttered the notes de¬ 
scribed under May 5. His flight reminded mo of an 
0wl*s. The rad markings beneath were very conspicu-' 
ous and when he turned his breast tov/ards me he looked 
like an adult Bjit.e.o Xineatus. The irides of the female 
were brovmish-orange. Her stomach was empty and she was 
rather fat. The nest was in a yellow pine am mixed 
pine and cedar woods bordering a maple swamp. It was 
in the top of the tree about thirty feet ab ve the ground 
It was composed outardly of sticks, and lined with strips 
of coarse, outer pine bark, and a-few tufts of fresh 
green pine needles. It was apparently constructed by 
the Hawks themselves for it was smaller than a Crow’s 
nest and differently put together. It contained 
five eggs incubated about three days. They were conspi¬ 
cuously blood-stained when taken but some of these marks 
washed off when the specimens were blown.
