Bridge ; have always found them in pairs, and have not as yet seen 

 more than two adults together. April the 21st saw a pair on Rock- 

 liffe rifle range. {E. F. G. White.) This form is very common along 

 the St. Lawrence, in eastern Ontario; it breeds on Wolfe island, and 

 about Kingston, also Frontenac and eastward through Leeds, 

 and Lanark; I did not meet with it in the county of Renfrew, but 

 it is common in the vicinity of Madoc, Hastings county. {Rev. 

 C. J. Young.) Regular sini^mer resident at Toronto, Ont., not 

 very common; reported as common at Beaumaris, Muskoka dis- 

 trict, by Mr. Taverner. (/. H. Fleming.) Fairly, common in 

 former years but less so now; still it will be found every mile or 

 two along the country roads; leaves us early in the fall; September 

 1 8th being the date of the latest observations ; extends into the Bruce 

 peninsula, where it is not common ; raises two broods annually. {W . 

 E. Saunders.) This was a common summer resident at Guelph, 

 Ont., a few years ago, but has been decreasing in numbers for the 

 past three years; this year (1903) it was very scarce; arrives about 

 March 26th, and leaves about August i8th. {A. B. Klugh.) 



Breeding Notes. — I took a nest of this bird containing one egg. 

 May 2oth, 1883, at Hochelaga, which was built in a thorn tree; I 

 visited the same place the following month, June 3rd, and found 

 another nest built by the same species in a thorn bush close to the 

 first, but some one had lodged a big stone in this nest ; I also found a 

 nest of this species. May 24th, 1888, at Laprairie, built in a bush 

 alongside the railroad track, and saw a shrike close to the nest; I 

 found another nest of this shrike, May 30th, 1891, at Hochelaga, 

 built in a thorn tree, containing two eggs, incubated, and June 6th, 

 1 891, Mr. IngUs found two fresh eggs of this bird in what appeared 

 to be an old nest, near the same place. (Wintle.) I have found this 

 bird to be the common species of shrike in eastern Ontario, for the 

 most part keeping along the St. Lawrence, apparently not going 

 further north than the county of Lanark ; at least I have never seen 

 it in northern Frontenac or in Renfrew county. It is a summer 

 migrant, arriving early in April. I have seen it as early as the 4th; 

 and commonly by the 17th; the nest is commenced about the end 

 of April and usually contains the complement of eggs by the first 

 week in May. If the first nest is destroyed, a second nest is built, 

 and eggs are laid towards the end of May; I have frequently met 

 with the nests; they are common about Lansdowne, Ont., on Wolfe
