CATALOGUE OF CANADIAN BIRDS, 603 
1901, I found the nest and four eggs of this species; nest of fine strips 
of bark, grass and fine roots, built in a poplar tree; at Long lake, 
Manitoba, on June 12th, 1894, I found a nest and four eggs of this 
species suspended to the branch of a willow, six feet from the ground.

627. Warbling Vireo. 
Vireosylva gilva (VIEILL.) Cassin. 1851. 
A common summer resident at Halifax, N.S. (Downs.) Not un- 
common at Calais, on the boundary of New Brunswick. (Cham- 
berlain.) A rare visitant in summer at Quebec. (Dionne.) A 
scarce transient visitant at Montreal; I have met with only two 
specimens of this species, which I took on Montreal island. (Wvnile.) 
An abundant summer resident around Ottawa. (Ottawa Natura- 
list, Vol. V.) A common summer resident, nesting high up in maple 
and elm trees, in eastern Ontario. (Rev. C. J. Young.) Regular 
migrant at Toronto, Ont.; not common. I have taken this species 
several times at Emsdale, Muskoka district, in May; Mr. Taverner 
has taken the species at Beaumaris, Muskoka. (J. H. Fleming.) 
Abundant along the city streets in London, Ont., but somewhat less 
so in the country; eggs usually four, but sometimes only three ; nests 
always high up, not less than twenty-five feet from the ground, 
while the red-eyed vireo seldom builds higher than eight feet and 
usually less; the male bird takes his share of the work of incubating, 
and sings freely while sitting. (W.E. Saunders.) Common summer 
resident at Guelph, Ont.; prefers city shade trees and orchards to 
the bush; arrives about May 8th, leaves about September 2oth. (A. 
B. Klugh.) Observed in abundance at Pembina, on the 49th parallel, 
and again found at the opposite extremity of the line, the specimen 
captured in the Rocky mountains, being probably the slight variety 
swainsoni; at Pembina the warbling vireo was in full song and breed- 
ing in June; a nest found on the 11th of that month was empty; but 
in this latitude few of the small insectivorous birds appear to lay 
before the third week in June. (Cowes.) Summer resident of wood- 
lands in Manitoba; common on the south slope of Riding mountain 
and west side of Duck mountain. (EF. T. Seton.) Rather rare at 
Aweme, Man., but not uncommon at Stockton, Man., and at some 
other points. Nests high up in tall trees. (Criddle.) Next to the 
red-eye this is the most abundant of the vireos in the west. Noted
