borough.) “Nery abundant summer resident in thickets at Prince 
Albert, Sask., arriving in May. (Coubeaux.) Common at Grand 
Rapids and at Chemawawin; breeding in thickets. (Vuiting.) Very 
abundant throughout the entire wooded regions of arctic 
America, where it builds on dwarf willows and small scrub pine 
at a height of a few feet from the ground. (Macfarlane.) This 
species is known throughout the Northwest Territories as far 
north as the woods extend, or to Lat. 68°. It reaches the banks 
of the Saskatchewan about the third week in May and Great 
Bear Lake in Lat. 65° in the beginning of June. (Azchardson.) 
North to Lapierre’s House on the Mackenzie River. (oss.) 
BREEDING Notes.—This warbler is very common along the St. 
John River, near Fredericton. Have never seen them more than 
a mile from a river or large stream where they nest in low bushes 
that grow about such places. The nest is seldom over-a yard 
from the ground, and have often seen them within a yard of the 
highway road. By the first week in June the majority of their 
eggs are laid, three and four being the number in aclutch. The 
nest is composed of plant fibres, dried grasses, wool and hair. 
(W. H. Moore.) Nest found in a lilac bush was composed of vege- 
table substance and down lined with hair and down, a very com- 
pact and neat affair, Eggs 5, grayish or greenish white dotted 
and blotched with reddish-brown and lilac. (G. R. White.) Nests 
in bushes, conifers and other trees around Ottawa. The nest Is 
placed two to fifteen feet from the ground, and composed of 
grayish fibres of plants and vegetable down with a few bits of 
grass, bark or feathers. The inside is white when not lined with 
hairs. This warbler often adds a story to its nest to cover up a 
cowbird’s egg laid in the original nest. (Garneau.) This bird builds 
a neat and compact nest and generally places it high up on the 
willows or in the forks of a small tree, rose bushes or wolf willow. 
It is chiefly composed of dead leaves of grasses and carices, and 
with a thick lining inside of small feathers, hairs and fine cottony 
wool gathered from the catkins of willows; numerous nests of the 
above character were detected in June, 1895, in southern AssintI- 
boia by the writer. .
