^70 BIRDS OF ONTARIO. 



It is a regular visitor in spring and fall, and Though not abundant i.s 

 very generally distributed. 



A few have been observed in Manitoba, and it has also been 

 reported as a straggler in Labrador, but from its lingering late in 

 the spring in Southern Ontario, and appearing again early in Sep- 

 tember, the bulk of the species probably does not go much farther 

 north to spend the summer. In the Auk, Vol. II., page 103, Dr. 

 Merriam gives an account of a nest of this species which he found 

 in Lewis County, N.Y., on the 2nd of June, 1879. It was saddled 

 on a limV) of a large pine, eighty-four feet from the ground, and 

 contained four fi-esh eggs of the owners of the nest and one of the 

 Cowbird. 



One of the few errors made by Wilson was his description of 

 the young of this bird as a separate species, which he named the 

 Hemlock Warbler. In this he was for a time followed by other 

 writers, till further observations brought (»ut the truth. 



Like most of its class, this species crosses the southern frontier in 

 May, and is again seen passing south in September.
