18S7.] General Notes. iGl. 



The adult males have the under plumage of a brighter yellow than that 

 of the one obtained last year; the color, however, is of a rather light shade, 

 not the deep yellow represented in Audubon's plates; the dark markings 

 on the crown and upper breast are similar to the one procured last year. 



The upper plumage of the adult female closely resembles that of the 

 male, except that there is no indication of black on the crown, and on the 

 front there is only a dull yellowish tinge; the under plumage is of a 

 lighter yellow than in the male, with a dusky, grayish patch on the lower 

 part of the neck, without any appearance of black as given in Mr. Audu- 

 bon's plate, though in his description he says ''fore-neck dusky." 



The young female is quite like the adult in its upper plumage, but has 

 the under plumage grayish, with just a tinge of yellow. 



Both sexes of the adult are of the same dimensions : length, 4.50 inches ; 

 wing. 2.37; tail, 2; bill, .44; tarsus, .70. The young measure a little 

 smaller. 



In the color of its upper plumage (excepting the crown) this species 

 closely resembles the Tennessee Warbler, and the young does somewhat 

 in the under plumage, but they are easily distinguished by the whitish 

 stripe over the eye and the dusky line from the bill to the eve in the Ten- 

 nessee Warbler. 



I requested Mr. Galbraith to note any peculiarity of habits, but he se- 

 cured none of the specimens himself, all being killed by his assistants ; 

 to one of the males is attached a label with the following account : "Killed 

 March 29, 1SS7; testes large. Killed on the upland ; seen to fly from the 

 ground to a small tree." 



He procured but nine specimens of Swainson's Warbler {Ilvlinaia 



swainsotii), which seems remarkable, as he collected so many more last 



year when not specially looking for them. They are probably local in 



heir habits, and the colony was reduced by the number obtained last 



year. — George N. Lawrence, Nc~v York City. 



[It may be of interest to add that three of the six specimens of Bach- 

 man's Warbler, mentioned above as obtained this year by Mr. Galbraith, 

 are now in the collection of Mr. William Brewster, and that the other 

 three, and also the specimen obtained by Mr. Galbraith in 1S86, are in the 

 collection of the American Museum of Natural History, New York City. 

 This increases the number of specimens taken in the United States to 

 eleven. Several specimens, as is well known, have been taken in Cuba. —

Birds laying their Eggs in the Nests of other Birds. — In 'The Auk' for 

 January, Mr. H. B. Bailey, of South Orange, N. J., reports the finding of 

 eggs of the Brown Thrush in the nest of the Wood Thrush. I have the 

 eggs of Coccyzus amertcanus and C. erythrophthalmus taken from the same 

 nest, two of the former and one of the latter. I think the nest was of 

 americanus, but I could not distinguish which bird was on the nest at the 

 time I found it.
