Park, Ont., in June and July, 1900. (.Spreadborough.) Not as com- 

 mon as formerly in summer though it still breeds in fair numbers 

 around London, Ont. {W.E. Saunders.) Common as a migrant, 

 breeding in varying numbers every year at Guelph, Ont.; arrives 

 about May 8th and leaves about August i8th. {A. B.Klugh.) One 

 specimen only of this distinctive species was secured at Pembina 

 — perhaps its western if not its northern limit. {Coues) A com- 

 mon summer resident in the wooded parts of Manitoba. Its 

 choice of locality usually causes it to be found chiefly in half-open 

 woods, especially along the edges of low, marshy places. It 

 frequents the tops of the highest trees. (Thompson-Seton!) Tol- 

 erably common at Avenue, Manitoba, where it very likely breeds.

Breeding Notes. — Found a nest in Beechwood cemetery near 

 Ottawa, which was built in an upright crotch about six feet from 

 the ground. The nest was a loosely woven mass of dried weeds 

 and fibrous substances lined with fine grass and horse-hair. Eggs, 

 4, white with reddish brown markings. {G. R. White.). Nests 

 around Ottawa in June and also at Lake Nominingue, 100 miles 

 north of Ottawa, in raspberry bushes and low shrubs; the nests 

 are made with grasses and strips of bark lined with vegetable 

 fibres and finer strips of bark; nest 3x2 and 2 x r25. (Garneau^ 

 On May 22nd of the past year (1900) not far distant from each 

 other, I noted two newly formed nests of this bird; the first seen 

 was deep in the underwood, and placed in the fork of a small 

 bushy maple about twenty inches off the ground; this was so 

 bulky and compactly built that at first I took it to be a nest of an 

 indigo bird; it was formed of a kind of woody fibre gleaned from 

 decayed timber, vines and grasses, and lined with long, black 

 horse-hair, which it must have taken the builder a good deal of 

 time, with much trouble, to collect and place in position; on the 

 above date this nest contained an t^% of the cow-bird, which I 

 removed and — five days after — it contained three eggs of the 

 chestnut- sided warbler, and on these the female was incubating, 

 and as the usual set of eggs of this species numbers four, it was 

 evident that the cow-bird had removed one of the warbler's when 

 she deposited her own ; this tramp among birds, is one of the 

 worst enemies with which the whole family of the warblers has 

 to contend, as many of their nests are found to contain one or 

 more of the cow-bird's eggs; and there is danger that the progeny
