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. (Coues.) Very 

 rare at Aweme, Man., may breed. {Griddle.) 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 9th, 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, tht 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 nth,
