in diameter. The nests are quite shallow, but are constructed 
similarly to those of the redstart. Eggs four. In former years 
the birds were much more common in the vicinity of London, 
Ont. (W. &. Saunders.) Nest andeggs taken at Drummondville, 
near Niagara Falls, Ont. (See Ridgway, Hist. N. Am. Birds, 1., 
1874, p.235.) A regular summer resident in southern Ontario, but 
local. One spring I searched for it carefully near Hamilton 
without seeing a single individual, while across the bay, four 
miles off, Mr. Dickson reported it quite common and breeding in 
the woods near the Waterdown station of the Grand Trunk Rail- 
way. (MclIlwraith.) 
BREEDING Notes.—I have two nests with sets of eggs of this 
species collected by Mr. Edward Reinecke, of Buffalo, N.Y. One 
nest containing four eggs was found on Navy Island, in the 
Niagara River. The nest was placed on the limb of an elm, near 
the top about 50 feet from the ground and very hard to get at.
