nest was ill-concealed, about four feet from the ground, and the bird 
left it when I approached. At a short distance it resembled a chip- 
ping sparrow‘s, but was composed outwardly of fine hemlock twigs, 
neatly woven, and was lined with hair and fibres. There were four 
fresh eggs, which were boldly marked, rather than spotted, with 
blotches of a dark brick-red on a creamy ground. I saw the bird 
leave the nest three times and identified it by the yellow markings 
and black on side of head. (Rev. C. J. Young.) This pretty little 
warbler arrives at Scotch Lake from the roth to 15th May, and 
within a week of the first arrival is common. They frequent young 
spruce trees in pastures and partly cleared land. They nest in June, 
building near the ground in small spruces and generally on the outer 
end of a small limb. They lay four eggs, and the period of incuba- 
tion is ten or eleven days, and the young stay in the nest about two 
weeks. (W. H. Moore.) A few pairs breed at Ottawa, while a 
great number go more to the north at Lake Nominingue. It nests 
in bushes of all kinds from one to four feet from the ground. The 
nests consist of small twigs, fine grass and rootlets, lined with hair 
or hair-like roots. (Garneau.) <A very full account of the nesting of 
this species in Compton co., Que., by Mr. L. M. Terrill was printed 
in The Ottawa Naturalist, Vol. XVIII., p. 150. 
658. Cerulean Warbler. 
Dendroica rara (WILS.) RIDGWAY. 1897. 
Rare spring migrant at Toronto, Ont. I have records of three 
males, May 24, 1890, May 20, 1893, and May 11, 1897; besides these 
there are four or five other local specimens, including a pair in the 
museum of Toronto University, taken in 1856. (J. H. Fleming.) 
Common in the southwestern part of Ontario, but rare near London 
and not extending much further north. A number of nests have 
been taken, varying from 25 to 60 feet above the ground and all 
saddled on fairly large limbs from { to 2 inches 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. FE. Saunders.) Nest 
and eggs taken at Drummondville, near Niagara Falls, Ont. (See 
Ridgway, Hist. N. Am. Birds, I., 1874, p. 235.) A regular summer 
resident in southern Ontario, but local. One spring I searched for it
