70 BREWSTER’S WARBLER. 
12. Meeker, Auk, 1906, 23, p. 104. Bethel, Conn., June, 1906. Chrysoptera 
3%, pinus 2, nest and five young. [One of them found, June 16, after 
leaving the nest, appeared to be a typical young pinus. A pinus @ was 
also present. Neither of the males was seen to feed the young, nor is it 
stated that either male was seen feeding the female. Proof as to which male 
was the mate of the female in this interesting case is therefore lacking in 
the published record. Moreover, pinus and leucobronchialis look so much 
alike at the time they leave the nest, that the author’s identification of 
the young bird as pinus is of no value unless he is very familiar with 
leucobronchialis in juvenile plumage.| 
13. Granger, Auk, 1907, 24, p. 348, Faxon, Auk, 1907, 24, p. 444, Maynard, 
Warblers of N. E., Addenda, 1908, p. 139-140, pl. xin. Jamaica 
Plain, Mass., June, 1907. Leucobronchialis @ mated with chrysoptera @ , 
nest and young. 
14. Maynard, Rec. Walks and Talks, 1908, 1, p. 79-80, Sherman, Auk, 1910, 
27, p. 444. Jamaica Plain, Mass., June, 1908. Leucobronchialis # 
mated with chrysoptera 9. [Same locality as No. 13.] 
15. Peters, The Wren, 1909, 1, p. 45. Braintree, Mass. Chrysoptera o@ and 
leucobronchialis 2, nest and young which died in the nest. 
16. Bishop, Auk, 1910, 27, p. 464. Woodmont, Conn. Lawrencet &@ probably 
mated with pinus 2, nest and four eggs; all were collected; June 4, 1909. 
To these sixteen cases are now to be added the two treated of in this paper, 
both of them being cases of the union of chrysoptera # with leucobronchialis ¢. 
Among observations belonging to the second category, 7. e., of young birds one 
of whose parents alone was seen but whose plumage nevertheless pointed to a 
mixed parentage I have noted the following: 
1. Brewster, Bull. N. O. C., 1881, 6, p. 220-221. Highland Falls, N. Y., July 7, 
1879. Lawrencet 9 with a young one which is clearly a lewcobronchialis. 
2. Fisher, Auk, 1885, 2, p. 378-879. Sing Sing, N. Y. Chrysoptera 2 feeding 
young with first-autumn plumage of pinus, July 4, 1885, yellow below, 
wing-bars white [Coll. J. E. Thayer, no. 8775]. Another of the young 
resembled the mother, no yellow on the breast. 
3. Bishop, Auk, 1894, 11, p. 79-80. New Haven, Conn. Leucobronchialis ( ? ?) 
feeding two young, July 4, apparently H. pinus. In one the wing-bars 
were white, in the other they were broader and light yellow.
