W. PUSILLA : GREEN BLACK-CAPPED WARBLER. I7I 



tested, but an unquestionable instance of such occur- 

 rence has lately been given by Mr. Deane (Bull. Nutt. 

 Club, V, 1880, p. 117). Mr. Merriam has supplied 

 our most extended and valuable notes on the subject, 

 derived from observations made in Connecticut. As 

 noted by Mr. H. A. Purdie (Am. Nat., vii, 1873, p. 

 692), the Hooded Warbler was found by Mr. J. N. 

 Clark to be abundant at Saybrook, "in dense woods, 

 breeding everywhere in suitable places, always in a 

 low laurel {^Kalmia) bush." (See, also, Mr. Purdie's 

 remarks in Bull. Nutt. Club, i, 1876, p. 73, and ii, 

 1877, p. 21.) The bird probably comes to New Eng- 

 land in May, and takes its departure in September.

Chars. Above, clear yellow-olive, the crown glossy black, the fore- 

 head, sides of head, and all under parts bright yellow ; wings 

 and tail unmarked, glossed with the color of the back : under 

 mandible pale. In female and young birds the black cap is ob- 

 scure or wanting. Very small : length, 4.75-5.00 ; extent, 7.00 ; 

 wing, 2.25 ; tail about 2.00. Bill Flycatcher-like, with strong bris- 

 tles, as in other species of the genus. 



Too little is known as yet of the breeding resorts 

 and habits of this dainty bird to enable me to speak 

 with assurance of the species as a summer resident in 

 New England. It occurs, however, in that character 

 in Maine, and doubtless also in New Hampshire and 

 Vermont, being apparently limited in its southward 

 range in the breeding season by the Canadian Fauna. 

 It goes north to the Arctic regions, having been found 

 nesting in Alaska, for instance. Eggs from the Yukon
