it is difficult to decide as to its relative abundance at Toronto. I 
seldom fail to see one or more specimens each season. (/. Hughes- 
Samuel.) A regular migrant at London, Ont., though never yet 
found to be common. Two or three are all that any one observer, 
will usually note in one migration. (W. E. Saunders.) Seen as a 
passing migrant at Guelph, Ont. (A. B. Klugh.) 
A peculiar song heard on Hill river, Keewatin, July 8th, was 
probably the song of this species, but I was unable to secure the 
bird. (E. A. Preble.) Although only two specimens were taken, it 
undoubtedly breeds about Pembina on the 49th parallel, in the 
heavy timber of the river bottoms, but I was not so fortunate as 
to discover its nest, a circumstance the more to be regretted, since 
neither the nest nor eggs have yet come to light. (Cowes.) Very 
rare at Aweme, Man., may breed. (Criddle.) An abundant breed- 
ing species in the wooded districts of Manitoba. (Atkinson.) 
Summer resident of thickets in Manitoba; nest found on Duck moun- 
tain. (E. T. Seton.) One was secured by Dr. Bishop in the Maple 
creek, Sask. timber on June 8th, 1906, in the great wave of migrants 
that passed through on that day. (A.C. Bent.) Not uncommon 
and breeding at Edmonton, Alta., in May, 1897. Not observed in 
any other locality west of Manitoba. (Spreadborough.) 
BREEDING NoTEs.—On June oth, 1884, near Fort Pelly, on the 
upper Assiniboine, I found a vireo nesting in a small bluff of poplar 
and willow; the chosen site was in the twigs of a willow some ten 
feet from the ground; the nest was the usual suspended cup formed 
of fine grass and strips of birch bark; on the ground immediately 
below it was another nest of precisely the same make and materials; 
intending to take this with me on my return I hung it in the-tree, 
but when I came back I found it on the ground, it was again hung 
as before, and again thrown down, although it had been firmly 
attached to a twig; this happened several times so that there was 
little doubt that it was the vireo’s doing, but why? I cannot 
imagine. On June 13th, the vireo began to sit on her four eggs; I 
shot her and found her to correspond exactly with Coues’ descrip- 
tion of philadelphica, except that the yellow on the breast was quite 
bright; the eggs closely resembled those of the red-eyed vireo, but 
were destroyed by an unfortunate accident before they were accur- 
ately measured. (E.T. Seton.) At Crescent lake, Sask., June 11th,
