HIKDS OF 



This " flying gem," clad in black and orange of the richest 

 shade, is by many regarded as the most gaily attired of all the 

 Warblers. It is a regular visitor in spring and fall, and though 

 not abundant is very generally distributed. 



From its lingering late in spring and appearing early in 

 September, it probably does not go much farther north to spend 

 the summer, but at that season it has not been observed in 

 Southern Ontario. One of the few errors made by Wilson was 

 his description of the young of the Blackburnian Warbler as a 

 different species, which he named the Hemlock Warbler. He 

 was for a time followed by other writers, till further observation 

 brought out the truth. Like most of its class this species crosses 

 the southern frontier during the early part of May, and is again 

 seen passing south in September.
