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 riflerange. (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 strrmer resident at Toronto, Ont., not 
very common; reported as common at Beaumaris, Muskoka dis- 
trict, by Mr. Taverner. (J. 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 
18th being the date of the latest observations ; extends into the Bruce 
peninsula, where it is not common; raises two broods annually. (IV. 
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 18th. (A. B. Klugh.) 
BREEDING NoTEs.—I took a nest of this bird containing one egg, 
May 20th, 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, 
1891, Mr. Inglis found two fresh eggs of this bird in what appeared 
to be an old nest, near the same place. (Wuntle.) 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
