CATALOGUE OF CANADIAN BIRDS. 597 
island, and in the vicinity of Kingston; one nest I found, built in a 
thorn bush about three feet from the ground, was completed on 29th 
April; on the 4th May, it contained five eggs, speckled and zoned and 
smaller than the eggs of L. borealis. The old birds were very tame 
and did not behave in the same way as those of the other species, 
which latter kept far off and perched high up in the trees; there 
were no large trees near this nest; May 6th, found a nest in a simi- 
lar location, containing four fresh eggs, birds were very tame, allow- 
ing of my approach within a few feet; April 3rd, 1890, I saw a pair 
of migrant shrikes, and on the 28th found the nest containing seven 
eggs in a thorn bush; on the 7th May found another nest with five 
eggs, incubated, built so low in the thorn bush that I could look into 
it when standing on the ground. April 18th, 1892, I found a migrant 
shrike’s nest in a thorn bush in a pasture field, which, on the 29th, 
contained six eggs; May 2nd, 1898, found a migrant shrike’s nest in 
a thorn bush with six fresh eggs; April 6th, 1899, I saw a pair of 
migrant shrikes, and their nest on the 29th April with six eggs, built 
as usual in a thorn tree in a pasture field, and no great height from 
the ground; I could refer to perhaps twenty other instances of this 
bird breeding as above in thorn bushes in pasture fields the last 
week of April or first week in May. (Rev. C. J. Young.) This bird 
begins its nest around Ottawa in April, and lays five, six or seven 
eggs; the nest is built in thorn trees or bushes from four to ten feet 
high, and is composed of branches, rootlets and strings, with woolly 
lining united to feathers and hairs. (Garneau.) A detailed account 
of the breeding of this bird in the vicinity of Ottawa, Ont., is given 
in The Auk, Vol. XXII., p. 314, by the Rev. G. Eifrig. 
622a. White-rumped Shrike. 
Lanwus ludovicianus excubitorides (SWAINS.) COUES. 1872. 
This is the characteristic species of the whole region along the 
49th parallel from Pembina to the Rocky mountains. At Turtle 
mountain, during the last week in July, I found a family of these 
birds in an isolated clump of bushes. The young, four in number, 
had just left the nest, which was discovered in the crotch of a bush 
five or six feet from the ground. The nest proper rested upon a 
bulky mass of interlaced twigs; it was composed of soine white weed 
(Anaphalis margaritacea) that grows abundantly in the vicinity, 
matted together with strips of fibrous bark. (Coues.)
