BIRDS OF NEW YORK 389 



young left the nest successfully (Auk, 21:387); on May 18, 1904, he or one of his descend- 

 ants returned to the park (Bildersee, Bird Lore 6: 131; Hix, Wilson Bid., 51,41). A male 

 was taken at Richmond, Staten Island, May n, 1907 (Chapin, Auk, 24:343).

Distinguishing characteristics. Like the Golden-winged warbler but lacking the 

 black patches on the check and throat, having the black eye streak of the Blue-winged 

 warbler and sometimes showing more or less traces of yellow on the breast and under parts, 

 and traces of yellowish green on the back, but retaining the yellow crown and yellow wing 

 bars of chrysoptera. 



This interesting warbler is now regarded like the Lawrence warbler as a hybrid between 

 the Blue-winged and Golden-winged warblers. It is much more common in collections 

 than the Lawrence warbler, numerous examples having been taken in Connecticut and 

 southeastern New York, as well as in northern New Jersey, and even eastern Massachusetts. 

 Doctor Fisher collected 6 specimens near Ossining, N. Y. (N. O. C. Bui. 4:234; 2:378; 

 and 6:219; Auk, 2:378). Mr Howell took a specimen at Parkville, Long Island (Auk, 9: 

 306), and another was taken at Nyack (Brewster, N. O. C. Bui. 6:219; Richer, Auk, 2: 

 378). The earliest specimen in New York is evidently a male collected by Bell at Rockland 

 in the spring of 1832 (Trotter, N. O. C. Bui. 44:459; Auk, 2:361). There seems little 

 doubt that this warbler is a hybrid like the Lawrence warbler, but unfortunately it has: 

 not been absolutely determined upon sufficient observation of birds reared by parents 

 of these two species, an observation which could easily be performed if mated birds of 

 these species were carefully watched and, instead of collecting the nests and eggs, the young 

 birds were studied in the nest, for their early plumages show the characteristic pattern 

 of the adults. 1 



1 Since the foregoing paragraph was written Doctor Faxon has proved satisfactorily that this warbler 

 is a hybrid of the Golden-winged and Blue-winged warblers (See Mus. Comp. Zool. Mem. 40; 31 and 16).
