THE NASHVILLE WARBLER. 415 



bunch of hypnum mosses, so that I take up the moss as a 

 part of the nest. The 5 eggs, well on in incubation, about 

 .62X.50, are clear white, sparsely specked and spotted all 

 over with light-red and reddish-brown, the markings thick- 

 ening into blotches at the large end. 



This instance of nidification agrees remarkably, especially 

 in the size and appearance of the eggs, with two instances 

 of that of the same species reported by Mr. Allen, from 

 Massachusetts, with others, more recently, by Mr. Peckham, 

 of Rhode Island the characteristics being that the nest, 

 which occurs early in the season, late in May or early in 

 June, is on the ground, and well concealed, having the eggs, 

 some .62X.50, milk-white, and moderately marked with 

 reddish tints. 



The song of this species is common about Manitoulin 

 and Strawberry Islands, and does not resemble that of the 

 Chestnut- side, which may be heard in contrast with it at 

 almost any time. The song of the Nashville Warbler is a 

 composition, the first half of which is as nearly as possible 

 like the thin but penetrating notes of the Black-and-white 

 Creeping Warbler, while the last half is like the twitter of 

 the Chipping Sparrow. As such a composition, its discov- 

 ery has been exceedingly interesting to me; and may be 

 imitated by the syllables, ke-tsee-ke-tsee-ke-tsee-chip-ee-chip-ee- 

 chip-ee-chip. 



About 4.50 long, olivaceous above, yellow beneath, head 

 slate, somewhat obscurely crowned with dark chestnut, its 

 slender and very sharp bill, without notch or bristle, declares 

 it to be one of the Helminthophaga genus. The sexes have a 

 very close resemblance, the female being simply a little 

 lighter and more obscure in color and marking. 



Seeming to winter in Mexico, this species passes through 

 Western New York as a common migrant the first week in
