Birds of The Palisades Interstate Park

was set beside the base of a fern clump, low on the ground. When 
it had served its purpose and the young birds had left it, I collected 
the nest. It was so constructed in the site among the stems that 
it had no firmness of walls to give it shape upon being removed. 
It was made of fragments of dead leaves and bark of shrubs and 
vines, with a very little bedding of fine grass, all the material being 
dark brown in color, and almost moist while in place. 
On June 14 I made further notes regarding the singing of the 
male Golden- winged Warbler in the dead chestnut top back of the 
Guest House, as a favorite vantage point for the utterance of its 
drawling, wheezy songs, where it sat bathed in the sunshine of the 
early morning. When thus singing the bird is not disturbed by 
observation, though it seldom remains long in one station. 
19. Blue-winged Warbler. Vermivora pinus (Linn.) 
The Blue-winged Warbler occurs in the Guest House neighbor- 
hood in about the same proportion of representation as at Bear 
Mountain. There is a particular piece of broken woods inter- 
spersed with shrubbery along the Tuxedo Drive, just beyond the 
junction of the Johnsontown road with it near the Guest House, 
and I mentally characterized this piece of bushy woodland as the 
“ Warbler Tract,” from the prevalence of certain species there, 
noticeably the Hooded Warbler, the Chestnut-sided Warhler, the 
Black and White Warbler, the Oven-bird, the Maryland Yellow- 
throat, the Redstart, the Worm-eating Warbler, and others. On 
July 9 in this “Warbler Tract” I observed a Blue-winged War- 
bler working along a little ravine in the place. The Blue-winged 
Warbler was making frequent trips through the ravine, among the 
lower branches of the large trees and surrounding saplings. It 
was easy to identify this warbler by its clear yellow under parts, 
narrow black line through the eye, and the white of the outer tail 
feathers frequently made conspicuous by the bird in its gleaning 
movements, like the Redstart. I was certain that the bird was 
feeding young in a nest up the ravine, but I did not hear it sing 
and was unable to locate its nesting place.
