48 TRANSACTIONS OP THE CANADIAN INSTITUTE. [VOL. III. 



Vireo olivaceus. — The Red-eyed Vireo's nests are found occasionally 

 but may be more common than supposed to be. 



Dendroica sestiva. — The Yellow Warbler's nests are to be found 

 everywhere, and every season, and are generally the depositary of the 

 Cowbird. 



Dendroica blackburnisa— In 1885 I found one nest of the Black- 

 burnian Warbler in a cedar tree north of Well's Hill. It was the only 

 nest of this species I ever saw here. It resembled that of the D. cestiva, 

 but a little smaller and shallower, it contained two eggs which were 

 marked very much similar to those of the Yellow Warbler. 



Seiurus aurocapillus— Oven-bird found occasionally on Well's 

 Hill. 



Setophaga ruticilla. — Redstart nests are found occasionally in the 

 deeper bushes north of the hill. 



Galeoscoptes carolinensis. — I find the Catbird's nests every year, but 

 in July 1885 I found a nest on the hill which contained one fully fledged 

 bird, one fresh egg and one addled egg. I took the addled egg and the 

 young bird, and returned in about two weeks and got another full fledged 

 bird. This is the only case I have known of fresh eggs and young birds 

 being found in the same nest around Toronto. 



Harporhynchus rufus. — I have found two or three Thrasher's nests 

 among the low scrub on the hill. 



Troglodytes aedon. — House Wrens' nests can be found in almost 

 every orchard or bit of bush around the city. They build in holes in the 

 side of a house or in a tree. 



Cistothorus palustris. — The Long-billed Marsh Wren's nests are 

 abundant in Toronto Marsh every year. 



Parus atricapillus. — Have found Chicadees' nests every year in old 

 stumps. 



Turdus fuscescens. — The nests of Wilson's Thrush are to be found 

 every year quite common in the deep woods. 



Merula migratoria. — The Robin's nest is about the most familiar to 

 all collectors, and is by far the most plentiful both in and outside the 

 city. 



Sialia sialis. — I find about two Blue-birds' nests every year, generally 

 in a hole in a tree or post, with a small hole just big enough to admit the-
