OF THE HAMILTON ASSOCIATION. 285 



Hab. Eastern North America to the Rocky Mountains, north to Green- 

 land, the Barren Grounds and Alaska, breeding from Northern New England 

 northward. South in winter to Northern South America. 



Nest, in an evergreen, 8 or 10 feet from th-i groimd ; built of larch twigs 

 woven together with moss and grass, and lined with fine grass. 



Eggs, 5 ; white, spotted with purple and reddish-brown. 



The Black-poll is a regular visitor in Southern Ontario in 

 spring and fall. It is the last of the family to arrive from the 

 south, beingseldom seen before the 20th of May. Its stay at this 

 time is of short duration, and when it goes the collector con- 

 siders the Warbler season is over. In the fall they are again seen 

 in increased numbers, many being in the young plumage, and 

 not in such haste to depart, although none remain over the 

 winter. 



The musical powers, if they have any, are not exercised in 

 this latitude, the birds while here being mostly silent. They 

 feed largely on winged insects, which are never plentiful till the 

 end of May, and this may account for the Black-polls being late 

 in arriving in spring.
