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 loth 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 Tlie Ottawa Naturalist, Vol. XVIIL, 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. (/. 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. E. 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
