Birds. yy 



above the ground, in a spruce tree. It was composed of hem- 

 lock and spruce twigs outside, then pine needles and dry- 

 grass, and lined with horsehair. The eggs (which we were 

 unable to save, they were so near hatching), were large for 

 the size of the bird, and darker colored than is usual with 

 Warblers' eggs.

BLACK-THROATED GREEN WARBLER. 



A common migrant. A not uncommon summer resident in 

 the northern part of the county. Breeds. Arrives April 29 

 to May 12. Nests taken June 4th and 26th, 1886. Both were 

 placed on a horizontal branch of a hemlock, about twenty 

 feet from the ground, in a little clump of branches, but riding 

 the horizontal limb; one on the edge of a heavy swamp, and 

 the other in a swampy place in a large piece of very heavy 

 timber. The nests were beautifully constructed, strong, com- 

 pact and deep. The outer sides about perpendicular, measur-

 side diameter, 3 to 3.50 inches; inside, 1.75 to 2 inches; com- 

 posed of green moss, birch bark, spider web, feathers, fine dry 

 twigs of the hemlock, lined with fine strips of bark and hair. 

 The eggs were rather a pointed oval; one set of three, white 

 with a pinkish shade, marked with fine spots of darker pink, 

 seCiTiing to show through, and quite strongly marked over 

 these with scattering blotches of light reddish brown with 

 much darker edges. They measured, .65 x .54, .64 x .52, 

 .64 X .52. The other set of two eggs were white, strongly- 

 blotched, especially at the larger end, with different shades of 

 brown and lilac, and measured .70 x .53, .70 x .51 inches.
