Birds of The Palisades Interstate Park

tlieir shrubby summits. Its favorite resorts are in timber where 
dead leaves are fairly exposed, with scattered fallen dead branches 
and a sparse growth of hardwood sprouts. I estimated that there 
was a singing male Oven-bird to every hundred yards of the trail 
up Bear Mountain. The Oven-Bird has brownish upper parts, a 
dull orange crown bordered with black, and spotted breast and 
sides. 
On May 27 I found a nest of the Oven-bird on the slope above 
the office building near the Inn (Fig. 17). It was concealed 
amongst the dead leaves around a fallen branch. It was made of 
coarse grasses, arched overhead, and the entrance opening was 
floored with a large spreading dead leaf, as a sort of doormat. A 
brood of four was produced in this nest. 
15. Chestnut-sided Warbler. Dendroica pennsylvanica (Linn.) 
This warbler is one of the common residents of the shrubbery 
throughout the Inn locality and everywhere in the Park domain. 
It is confiding in its disposition, of unsuspicious nature, and not 
averse to carrying on its business regardless of close observation of a 
quiet kind. It is a handsome little warbler, with conspicuous mark- 
ings, having the top of the head yellow, sides of the throat black, 
and a chestnut stripe along the sides, partially concealed by the 
folded Avings, which have yellowish bars. The song has a charac- 
teristic ending easily identified after close attention. The general 
song I annotate as follows : “ Sweet sAveet sweet SAveet, see Avee 
cheAV ”, with the second note of the ending, the syllable “ Avee ”, 
made emphatic. 
On May 29 I found a nest of the Chestnut-sided Warbler along 
the road near the southeast entrance to the Inn grounds. It Avas 
in the shrubbery below the parapet, near the margin of the under- 
groAvth. The site was in a very slender sprout, about three feet 
from the ground, where a slender creeping vine crossed a weak 
fork of the sprout (Fig. 18). The nest is constructed almost 
Avholly of narroAv dried grasses, Avith a scant amount of weed bark, 
Avoven rather loosely together, and lined Avith fine broAvn grasses 
and some horsehair. This nest produced a brood of four in due 
time.
