55.-Vireo solitarius. Solitary Vireo. — None were observed in 
1899, but very possibly they were overlooked. In 1900, I heard them a 
number of times, and after some difficulty, secured one specimen — a 
breeding female. 
Although the males move about considerably while feeding and sing- 
ing, they were apparently confined to three localities, a half mile or 
more apart, and I concluded that there were probably but three pairs 
breeding in the section of country that I explored. Their habitat is the 
heavy mixed growth, at the east base of the mountain ; the specimen 
taken was on a dry ridge clothed with spruces, firs, and hemlocks. 
They are rather shy, and have a habit of moving restlessly from point to 
point, always keeping well out of sight, but singing at frequent intervals.
