Visited a swamp in Lincoln to hunt for a nest of 
one of these Owls which has regularly bred there for sev¬ 
eral seasons. This nest v/as first found in 1873 by 
Dwight Whiting; it was then occupied by a pair of Red¬ 
tailed Hawks whose eggs Mr.Whiting took. Visiting it 
again the ne*t season he found it had been appropriated 
by the Owls who had hatched oyt two young in it one of 
which was taken._ In 1875 it was again visited by Fra^ 
found it empty but caught one of the young Owls 
(which was able to fly only a short distance) in the im¬ 
mediate vicinity. Prazar tells me that at that time 
the nest v/as nearly four feet in external diameter. It 
was in the extreme top of a white pine at a height of 
about thirty five feet. The thee, which I examined to¬ 
day, was about two feet in diameter. It stood on the 
extreme edge of an extensive pine swamp and overlooked an 
adjoining tract of swampy maple and ash growth. Pra¬ 
zar saw one of the birds here about a week ago. but we 
found neither them nor their nest to-day

Saw one, the male apparently, in the pine swamp in 
Lincoln where Frasar found the nest. It was exceedingly 
Shy as usual; and was followed by a mob of Crows. 
A number of pellets found in this haunt were of enormous 
composed entirely of skunkft hair and bones 
among them all the claws of both front feet ’
