Rideau river, in April, 1903. OnAprilthe 6th, 1904, saw the first 
pair for this year, and on April the 18th, saw five pairs along the 
Rideau,between Cumming’s and Billing’sBridge, have always found 
them in pairs and have not as yet seen more than two adults 
together. April the 2Ist saw a pair on Rockliffe rifle range. 
(Z. 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, 
Lanark and to the limit of Ontario; I did not meet with it in the 
county of Renfrew; it breeds in a thorn bush early in April and 
usually lays six eggs about April 19th; the nest is large and 
strong placed from five to ten feet from the ground. (Rev. C /. 
Young.) Reported as common at Beaumaris, Muskoka district by 
Mr. Tavernier. (/. 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 penin- 
sula where it is not common; raises two broods annually. (IV. £. 
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. (4. B. Kluyh.) 
BreepinG Nores.—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 n st built by the same species ina thorn bush close to 
the first, but some one had lodged a big stone in this nest; I also 
fourd 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 Hoche- 
laga, 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. (Wntle.) 
Ihave 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 asummer 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 com-
