667 Dendroica virens (Gmelin). 

 Black-throated Green Warbler. 



Adult male. Length, 4.50-5.25. Wing, 2.50. Above, yellowish olive-green, 

 some of the feathers of the back centered with black ; wing-coverts broadly 

 tipped with white, forming two bands ; three outer tail feathers with large 

 white areas on the inner webs ; forehead, cheeks and sides of neck, and broad 

 line over the eye, bright yellow ; throat, breast and sides of body, black ; middle

 with long yellowish tips to the feathers. In the female there is no black on 

 the breast and only black streaks on the sides. 



Nest in trees or sometimes near the ground ; , eggs, three to four, white, with 

 a wreath of brown and lilac spots, .60 x .50. 



Common transient visitant. Spring, April 28th (May 3d) to May 

 15th; autumn, September 1st to October 10th. 



Only one nest of this species has been found in the State. It was 

 discovered by Mr. B. S. Bowdish, at Demarest, June 5th, 1904. 1 That 

 it may prove a regular summer resident, in the same region, is sug- 

 gested by the fact that Messrs. S. N. Rhoads and Wm. B. Evans found 

 it at Alpine, on the palisades, in June, 1901, 2 and in June, 1909, Mr. 

 Rhoads found them evidently breeding at Greenwood, Wawayanda and 

 Echo Lakes. 



An easily recognized member of the spring Warbler host, with a 

 most distinctive song, "pee, tee, chee-o, tee," as given by Professor 

 Jones, the third and fourth notes joined together and representing a 

 drop from the former pitch, to which it returns on the last note ; the 

 first, second and fifth are short or staccato. 



671 Dendroica vigors! (Audubon). 

 Pine Warbler. 



Adult male. Length, 5-5.50. Wing, 2.75-3. Above, olive-green; wings and 

 tail, dusky, the former with two whitish wing bars, the latter with large white 

 areas on the inner webs of the two outer pairs of feathers ; below, yellow, with 

 indistinct dusky streaks on the sides of the breast; middle of abdomen and 

 under tail-coverts, white; a faint line of yellow just above and below the eye. 

 In autumn the colors are softer and more blended.
