358 BIRDS OF ONTARIO. 



The range of this species is chiefly along the west coast oi- 

 midclle district of the continent. In the east it occurs rarely. As a 

 straggler, I have met with it only on two occasions, the latter being 

 on the 11th of May, 1886, when a specimen was taken at the Beach 

 by K. C. Mcllwraith. Mr. Saunders mentions having obtained two 

 near London, and Mr. Allan Brooks got one at Milton. 



It is a very plainly attired species, and may readily be overlooked, 

 for there is nothing in its dress or manner to attract attention, but 

 on close examination the color of the crown patch is a distinguishing 

 mark not likely to be mistaken. The sexes closely resemble each 

 other, and the young are like them, except that they do not always 

 have the brown crown patch till after the first year. 



They are by no means conspicuous birds, but they have their own 

 route to follow, and keep by it regularly every season. 



Province, county, township, territory are passed quietly over till 

 they reach the far distant land of Alaska, where Mr. Nelson says 

 they have been observed throughout the wooded region of the north 

 from the British boundary line, west to the shores of Behring Sea,, 

 and north within the Arctic circle as far as the tree limit. They 

 breed throughout the interior, and Kennicott secured a set of eggs 

 on the 10th of June and another on the l.^th of the same month. 



HELMINTHOPHILA PEREGRIN A (Wils.). 

 L'66. Tennessee Warbler. (647) 



Olive-green, l>rightei- l)eliiii(l, but never qiiite yellow on the tail coverts, 

 more or less ashy towards and on the head; no crown patch; below, white, 

 often glossed with yellowish, but never quite yellow ; a ring round the eye 

 and superciliary line, whitish, frequently an obscure whitish spot on outer 

 tail feathers ; lores, dusky ; in the fe/nale and yoaitg, the olivaceous glosses the 

 whole upper parts. Length, 44-4| ; wing, about 2^ ; tail, 2 or less. 



This comparative lengtli of wing and tail, with other characters, proba})ly 

 always distinguishes this species from the foregoing. 



Hab. — Eastern North America, l)reeding from Northern New York and 

 Northern New England northward to Hudson's Bay Teri'itory ; Central 

 America in winter. 



Nest, on or near the groun<l, l)uilt of grasses, mosses and l)ark strips, lined 

 with fine grass and hair. 



Eggs, foui', white, witli markings of I'eddish-brown about the larger end.
