CATALOGUE OF CANADIAN BIRDS. 243. 
B.C. (Macoun.) Seen at Penticton, Meyers creek and Sidley, B.C. 
(Spreadborough.) Abundant on the mainland of British Columbia 
at Sumas, Chilliwack, mouth of the Fraser, and east of the Coast 
range. Partially migratory. A few are found throughout the 
winter in the neighbourhood of Ladner’s, near the mouth of the 
Fraser. (Fannin.) Observed in winter at Lake Okanagan, B.C. 
(Brooks.) Noted at every stopping-place in British Columbia. 
Nowhere abundant. (Rhoads.) These birds are numerous through- 
“out northern Alaska during the migrations. They are seen frequent- 
ly along the barren coast of Bering sea, and have been recorded as 
rather uncommon in the interior. (Nelson.) This bird appears 
to be a resident of the Yukon district only between the early part 
of April and late November. The species is a rare summer visitor 
on Attu island. (Turner.). I saw this species at Cape Blossom, 
Kotzebue sound, Alaska, on two occasions. Marsh hawks were 
frequently noted at our winter camp on the Kowak the last of 
August. (Grinnell.) Seen at several places in the interior of Yukon 
and Alaska in 1899. One was seen at Homer, Alaska, and another 
at Hope, in 1900. Noted at Nushagak, and by the Chulitna and 
Kakbitul rivers, Alaska peninsula. (Osgood.) Hawks are not 
common in the Cook inlet region, Alaska. This species is probably 
the most common. It was seen at all points visited. (/*iggins.) 
BREEDING NoTes.—This species breeds frequently in the neigh- 
bourhood of Ottawa. Its nest is composed of dry grass with a few 
dry sticks, probably to strengthen it. There is an inner lining of 
feathers few and far between to form a bed for the eggs, which are 
from four to six in number, of a dull white with the faintest shade 
of green and soiled, but no decided spots on them. The nest is 
built on the ground, or at the base of ‘a low bush near a marsh, 
about the middle of May. (G. R. White.) Besides in the large 
marshes and the small ones, this bird will even breed in an unculti- 
vated field at times, and is, if anything, more common than formerly. 
Nest on the ground, among shrubs, generally in a swampy place. 
Eggs four or five, white, rapidly soiled. (W. E. Saunders.) An 
abundant breeding species everywhere throughout Manitoba and 
west through Manitoba, Saskatchewan and Alberta. Noted breed- 
ing in all stages of plumage from reddish brown of first year to blue 
of mature birds, but also note that pairs are always alike in plumage. 
I never saw a red marsh hawk with a blue mate. (Atkinson.)
