Evidence Concerning the Interbreeding of Helminthophila chrysop- 

 tera and H. pinus.— On July 4, 1885, while collecting specimens in a piece 

 of woods underlaid by a scattering undergrowth, I came upon a female 

 Golden-winged Warbler busily engaged in collecting insects. As I stood 

 watching her she fiew to a neighboring cedar tree and commenced to feed 

 a young bird. I immediately shot and kiUed the latter as the female flew 

 away. The noise of the discharge started another young bird from some 

 bushes near by, and as it flew the female flew and alighted near it. Just as 

 I was on the point of firing they started, and I succeeded in wounding the 

 female only and had to follow and kill her with a second shot. On my 

 return to the place where I first shot at her, I could not find the young 

 one, nor did a careful search disclose it. In advancing tor a nearer shot I 

 had a good opportunity of seeing the young bird : it closely resembled its 

 mother in appearance and had no yellow on the breast, whereas the one 



killed was the exact counterpart of the young of the Blue-winged Yellow . 

 Warbler, with its yellow breast and white wing-bars. 



In all probability the father of this interesting family was a specimen of 

 Helminihof>hna phms.—l\. K. Fi.sher, M. D., Sin^ Sinff, Neiu Tork. |

DESCRIPTIONS OF THE FIRST PLUMAGE IN VARIOUS 

 SPECIES OF NORTH AMERICAN BIRDS. 



BT WILLIAM BREWSTER. ,

24. Helminthophaga chrysoptera. 



Fall plumage : male. Upper parts bluish-gray, washed strongly with 

 olive-green on the back. Forehead and crown yellow, somewhat ob- 

 scured by greenish streaking. Occiput bright greenish-yellow. Patch on 

 wings clear yellow. Band through the eye and entire under parts, as in 

 the aditlt. Chin, throat, and jugulum black, each feather broadly edged 

 with soiled white. White maxillary stripes fairly meeting on anterior 

 portion of chin. (This last feature may probably be explained by hidi- 

 vidual variation, not by age. I have seen many adults similarly charac- 

 terized.) 



Fall plumage : female. Remiges, rectrices, etc., as in adult. Pileum 

 and nape uniform olive-green ; back and rump bluish-gray, washed with 

 greenish-olive. Upper tail-coverts clear bluish-gray. Sides of head and 

 entire under parts with a slight wash of brownish-yellow ; otherwise col- 

 ored like the adult. From two specimens in my collection shot at Cam- 

 bridge, Mass., July 18, 1874. It may be well to mention that these birds 

 are in somewhat transitional dress, and have .hardly, perhaps,. passed from 

 the first plumage, hut as the female differs but little from a specimen of 

 the same sex in the perfected fall dress, taken August 21, 1875, I have 

 thought it best to describe them both as in full autumnal plumage.
