1911 J General Notes. 3/1 



the owners of the nest were a male Helminthophila leucobronchialis and a 

 female H. ckrysoptera, as both birds were seen about the nest. About 

 five days after I found the nest the young disappeared, just how will never 

 be known. 



A few days after the disappearance of the young birds a nest was found 

 across the road and was believed by Mrs. Sherman and others who did 

 not know of the first to be that of leucobronchialis. So far as I am aware 

 the determination of the ownership of the nest was based entirely upon the 

 identification of the female, which was described in ' The Auk ' by Mrs. 

 Sherman as having " a dark dusky throat-patch, not clearly defined at 

 its base, but blended into the pale gray of the upper breast. . . .The black 

 line through the eye was broader and extended back farther than did that on 

 the Brewster of the preceding year. She differed also in showing two 

 yellow wing-bands." This description applies perfectly to the female 

 of ckrysoptera and as there was a male of this species singing not far from 

 the nest in question it is not at all unlikely that he was the owner and not 

 the leucobronchialis, as one might be led to believe. 



In 1909 and 1910 the straight male chrysoptera was the only bird to be 

 seen; in the Arboretum no female was seen or nest found in either year. 



Mrs. Sherman describes (I. c, pp. 444, 445) a pair of Goldenwings which 

 bred in Roslindale in 1910. The male was a typical chrysoptera ; the female, 

 which had been identified as leucobronchialis, had much the same plumage 

 as the one she had just described (see above), but differed in having " the 

 dusky throat patch lighter in color. It bore the same character in being 

 darker towards its center and directly under the bill. The one in 1908 

 had a nearly black throat patch, mottled slightly in appearance. The black 

 line through the eye was narrower and paled on a pale gray cheek. The 

 white line above the eye was uniform in width .... The white line below the 

 eye was shorter. The whole tone of the back was more olivaceous. Two 

 bright yellow wing-bars divided by an olive or dark band on the wing. 

 The entire underparts were washed with yellow which showed quite bright 

 on the middle of the breast in a good light. The crown was bright dande- 

 lion yellow running into bronzy yellow on the back of the head." 



This description seems to be a rather good one of a female Helminthophila 

 chrysoptera in very high plumage. 



It has always been believed that the females in the Arboretum in 1907 

 and 1908 were chrysoptera, and I see no reason why either of these birds 

 or the one in Roslindale should ever be regarded as anything else. — James

Black-throated Blue Warbler (Dendroica cmrulescens coeruUscens) 

 Nesting in Sterling, Massachusetts. — I have been collecting about 

 Lancaster, Mass., since 1897 and I have never found but one Black- 

 throated Blue Warbler's nest until today. 



My friend Mr. Herbert Parker told me he had found what he was sure 

 was a Black-throated Blue's nest, in Sterling, which is the next town to
