this point was about to be concluded, as female specimens pre- 
ponderated; the species was not observed further west on the 4gth 
parallel. (Coues.) Not an uncommon summer resident in the 
wooded parts of Manitoba, apparently breeding on Duck Moun- 
tain. (Zhompson-Seton.) 
This isa common migrant at Indian Head, Assa., and very 
likely breeds ; first seen May 31st, and soon became common in 
willow thickets where it remained to June 15th, when all disap- 
peared ; first seen at Medicine Hat, Assa., May 18th, 1894; others 
were seen afterwards, but they were never numerous; a few seen 
on Old Wives’ Creek, Assa., late in May, 1895; a common breed- 
ing species at Banff, Rocky Mountains, in the summer of 1891 ; 
common in willow thickets from the mouth of Slave River to 
Peace River Landing, Lat. 56° 15’ in June, 1903 ; first seen on 
May 22nd, 1897, at Edmonton, Alta.; tolerably common along the 
creeks by the 28th; no doubt they breed here ; common from 
Edmonton to the Athabasca Pass in willow thickets in low ~ 
grounds and along streams in June, 1898; common in the 
foothills south of Calgary. (Spreadborough.) Common at the 
Grand Rapids of the Saskatchewan, where it doubtless breeds. 
(Nutting.) One of the most abundant birds between Athabasca 
Landing and Lesser Slave River; first noted May 30th ; common 
down the Athabasca River to Fort McMurray, Lat. 56° 40’; com- 
mon up the Clearwater River and at the north end of Methye 
Portage; common between Methye Lake and Isle a la Crosse 
Lake ; last seen August 1oth. (/. 47. Macoun.) One specimen. 
only was procured at Cumberland House, on the banks of the 
Saskatchewan, in the latter endof May. (¢chardson.) North to 
Fort Simpson on the Mackenzie River. (oss.) I have a nest 
and four eggs of this bird collected at Fort Saskatchewan near 
Edmonton, Alta., on June 12th, 1899, by Mr. J. Callaghan; nest in 
a willow two feet from the ground. (W. Raine.) This was a 
common breeder at 158-Mile House, B.C., where its sharp insistent 
song was to be heard from every copse in the partially wooded 
district. (Brooks.) Found only at Caribou Crossing, Lat. 60°, 
B.C., where I heard four males singing and secured three of them, 
June 27th and 28th, 1899. They were in comparatively open wil- 
low and spruce swamps. (Szshop.)
