564 THE BIRDS OF MAINE 



parent at Gaines, Orleans Co., New York, June 2, 1896, and 

 recorded at the time by, I think Mr. Short in the Oologist, 

 since which I acquired the set by purchase from Mr. Short. 

 The nest is composed externally of narrow strips of pellucid 

 bark and a few sedges, lined with fine grass and hair. It is 

 two inches deep outside by one and a half inside, while the 

 diameter is three and a half outside by one and three-quarters 

 inches inside. The eggs are white speckled with chestnut, 

 umber and lilac gray, tending to form a wreath about the 

 larger ends to which the marks are chiefly confined. One 

 egg is almost entirely marked with suffused lilac gray about 

 the larger end while the others are strongly and boldly marked. 

 They measure 0.68 x 0.53, 0.66 x 0.51, 0.65 x 0.53. The 

 ever ready Cowbird had added one of its own eggs to this set 

 and the intruder's egg measures 0.96 x 0.60. Generally four 

 or five eggs are said to be laid. 



685. Wilsonia pusiUa(Wih.}. Wilson's Warbler; Wilson's 

 Black-cap; Green Black-capped Fly catching Warbler. 



Plumage of adults: crown black; forehead yellow; otherwise above 

 bright olive green ; below bright yellow ; the adult breeding female often 

 has fully as much black in the crown patch as the adult male does and in 

 many cases the two sexes are not distinguishable in plumage, other writers 

 to the contrary notwithstanding. Immatvure plumage : very similar indeed, 

 but the black cap is lacking or sometimes indicated by a few black feathers, 

 edged with greenish olive. Juvenal plumage : above hair brown, mottled 

 with sepia ; wings and tail olive brown, edged with greenish ; below yellow, 

 washed with pale brown on throat and sides. Wing 2.25 ; tail 2.10. Bill 

 with bristles at base. 



Geog. Dist. — The breeding range extends from northern Maine and north- 

 ern Minnesota to Lake Athabaska, Labrador, Hudson Bay and Newfoundland, 

 being essentially a bird of the Canadian and Hudsonian faunje ; wintering 

 on the Atlantic slope of the mountains of Central America from Guatemala 

 to Costa Rica, occasionally wintering as far north as Yucatan.
