THE BIRDS OP NEW JERSEY. 261 



Common, but local summer resident. Arrives May 2d (May 6th), 

 depr-rts September 25th. 



The \\'arbling Vireo is a bird of the shade trees of the village streets 

 and lawns, with the habits of other Vireos, but an entirely different 

 song ; a fine continuous warble, recalling somewhat the song of the 

 Orchard Oriole, a bird of similar surroundings. It is more or less 

 local and apparently more plentiful in the northern half of the State. 

 Mr. F. M. Chapman found it at High Knob, Sussex county, and it is 

 abundant in the Wallkill Valley (Rhoads). 



628 Lanivireo flavifrons (Vieillot). 

 Yellow-throated Vireo. 



Adults. Length, 5-5.75. Wing, 3. Above, yellowish-olive; scapulars, rump 

 and upper tail-coverts, gray ; wings and tail, black, most of the feathers nar- 

 rowly edged with white ; two conspicuous wing bars ; under parts, bright 

 canary-yellow, tinged with olive on the sides ; abdomen and crissum, pure 

 white ; lores and eye ring, yellow. 



Youny in first summer. Smoky gray above, white below ; chin and throat, 

 pale yellow. 



Nest pensile from a high branch similar to that of the Red-eye, but covered 

 externally with lichens ; eggs, three to four, white, spotted sparingly at the 

 larger end with black and brown, .80 x .60. 



Tolerably common summer resident. Arrives April 29th (May 3d), 

 departs September 15th. 



The Yellow-throated Vireo is a bird of the tree-tops, and hence is 

 not so well known as the Red-eye, and may be more plentiful than we 

 suppose. His notes are stronger and sweeter than those of the Red- 

 eye, with a longer pause between, and there seems to be three slightly 

 varying phrases repeated in the same order again and again, the first 

 decidedly harsh : "See saw I'm up here You're down there." 



629 Lanivireo solitarius (Wilson). 

 Blue-headed Vireo, Solitary Vireo. 



Adults. Length, 5-G. Wing, 3. Above, olive-green, mixed with slate-gray on 

 the back ; head, plain slate-gray ; wings and tail, black, the feathers mostly edged 

 with white or yellowish ; two prominent wing bars ; under parts, silky white, 

 yellow-olive on the sides ; eye ring and lores, white, with a dusky spot just 

 before the eye, extending onto the eye ring. 



Nest and eggs similar to those of the Red-eyed Vireo, .80 x .60.
