ONTARIO. 



Beach by K. C. Mcllwraith. Mr. Saunders mentions having 

 obtained two near London, and Mr. Allan Brooks has got one 



in Milton. 



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

 looked, 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. 



253. HELMINTHOPHILA PEREGRINA (WiLS..). 647. 

 Tennessee Warbler. 



Olive-green, brighter behind, but never quite 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 female and young the olivaceous glosses 

 the whole upper parts. Length, 4^-4! ; wing, about 2% ; tail, 2 or less. 



This comparative length of wing and tail, with other characters, prob- 

 ably always distinguishes this species from the foregoing. 



HAB. Eastern North America, breeding from Northern New York and 

 Northern New England northward to Hudson's Bay Territory ; Central 

 America in winter. 



Nest, on or near the ground; built of grasses, mosses and bark strips, 

 lined with fine grass and hair. 



Eggs, 4 ; white, with markings of reddish-brown about the larger end. 



The Tennessee Warbler breeds in the Hudson's Bay 

 Territory, where it is by no means rare, but the line 

 of its migration seems to be along the Mississippi Valley, 

 so that in the east it is seldom seen. I have only met 

 with it twice, once in spring and again in the fall. It is probable 

 that a few visit us with the migratory birds every season, but 

 like one or two others it may owe its safety to its plain attire, 

 being allowed to pass, while one of more gaudy plumage would 

 be stopped.
