no SYLVICOLID^ : AMERICAN WARBLERS. 



They are white, blushing when fresh, and speckled all 

 over. According to Minot they " vary between the 

 extremes of being finely and thickly marked about the 

 crown witli lilac and being thinly and coarsely blotched 

 at the greater end with reddish-brown, these markings 

 being sometimes combined." In size the eggs range 

 from 0.60 to 0.63 in length by 0.48 to 0.52 in 

 breadth. The nest of this bird is one of the many 

 known to be appropriated by the Cowbird at times. 

 The Nashville Warbler reaches New England early in 

 May, and departs by the end of September. It is most 

 numerous during the fall migration, and in many lo- 

 calities shows an evident preference for coniferous for- 

 ests, though it may be found indifferently in any kind 

 of woodland and shrubbery. It is not a very conspic- 

 uous bird, either in dress, voice, or action, and is 

 hence often supposed to be less numerous than it really 

 is, being overlooked amid the throng of Warblers that 

 pass through our woods, except by those observers 

 whose eyes and ears are trained in the exercise of 

 discrimination. 



ORANGE-CROWNED WARBLER. 



Helminthophaga celata {Say) Bd. 



Chars. Above, nearly uniform olive-green, rather brightest on rump, 

 but never ashy on head. Below, greenish-yellow, olive-washed 

 on sides ; a concealed orange-brown crown-patch (often wanting) ; 

 a yellowish eye-ring and supraciliary line. " Size of the last, and 

 often difficult to distinguish in immature plumage ; but a general 

 oliveness and yellowness compared with the ashy of some parts 

 of nificapilla, and the different color of the crown-patch of the 

 two species, will usually be diagnostic." /
