me in the tree tops and going on, moving rather energetically from 
one tree to another as he uttered his songs. Selecting what I 
thought to be the center of his song range, I began to search the 
shrubbery, and soon my eye caught sight of the nest. It was in 
chestnut sprouts, at the base of two tall slender oaks (Fig. 26). 
The nest was fairly well exposed, in a very slender forking chest- 
nut sprout, about eighteen inches from the ground, the slender 
sprout being supported by a stronger dead sprout. It was a strong 
nest, with compact walls made outwardly of coarse bark strippings 
and vegetable fibers, with some coarse loosely hanging bark and 
skeleton leaf material (Fig. 27). On that day the nest contained 
two eggs, but no female was seen near it at the time, and only 
after a half hour’s wait did I hear a faint “ chip ” announcing her 
presence nearby. On June 18 I visited the place, and there were 
four eggs in the nest. 
The Black- throated Blue Warbler was not seen by me elsewhere 
in the Park, and this incident of its nesting was exceptional. 
17. Yellow Warbler. Dendroica cestiva cestiva (Gmel.) 
The Yellow Warbler did not appear to be any more common in 
the Guest House neighborhood than at Bear Mountain. In fact, 
my only note of its occurrence was on June 28, when a specimen 
was observed at Kanahwauke Lake, among the sapling growth at 
the roadside near the bridge. 
18. Golden-winged Warbler. Vennivora chrysoptera (Linn.) 
It was at the Guest House that I had opportunity to study 
advantageously the interesting Golden-winged Warbler. On 
June 9, my first day of observation, I noted frequently the singing 
of this warbler in the trees at the rear of the House, and particu- 
larly in the bare top of a dead chestnut rising above the shrubbery. 
On June 12 I located a pair of Golden- winged Warblers feeding 
young in a nest hidden among swamp ferns in the edge of a little 
swamp along the road, on the premises immediately adjoining the 
Guest House lot on the east. After getting a fair idea of the loca- 
tion of the nest, I got down among the ferns, and, parting the 
soaked vegetation carefully with my hands, I found the nest. It
