Observed during the fall migration, in September, along the 
Mouse (Souris) river, where it was abundant. (Coues.) Common 
summer resident in woodlands, in Manitoba; evidently breeding in 
the woods around Carberry. (&. T. Seton.) First seen at Aweme, 
Manitoba, on May 12th, 1903, was common on the 17th and dis- 
appeared on September 16th. A common breeding species. (Crid- 
dle.) This is a rare summer migrant at Indian Head, Sask. It was 
first seen at Indian Head, May 2oth, 1892, and disappeared on the 
25th; first seen at Medicine Hat, Sask., May 9th, 1894, common by 
the 15th, and were all gone by the 20th. (Spreadborough.) Com- 
mon in families of flying young in the Cypress hills, Sask., July 25th, 
to 30th. No adult males found. (Bishop.) North to Fort Resolution 
on Great Slave lake; rare. (Ross.) This is one of the rarest warb- 
lers that breeds on the Anderson river where four or five nests were 
found containing from four to six eggs. The nests were made of hay 
or grasses, lined with deer hair, feathers and finer grasses, and were 
found on the ground in the shade of a clump of dwarf willow or 
Labrador tea. (Macjfarlane.) Throughout the wooded region of 
northern Alaska, from the British boundary line west to the shores of 
Behring sea, and from the Alaskan range of mountains north within 
the Arctic circle as far as the tree limit, this species is a summer 
resident. (Nelson.) Two individuals of this species were shot 
among the weeds surrounding the redoubt at St. Michael. They are 
not common as they were the only ones ever seen at that place. 
(Turner.) Two specimens taken at Ducks were of this form. 
(Streator.) East and west of Coast range; a summer resident. 
(Fannin.) Tolerably common during the migrations at Chilliwack. 
A scarce summer resident in the Cariboo district, of B.C.; both old 
and young birds showed typical celata. (Brooks.) Five specimens 
from the interior of British Columbia are distinguishable from the 
coast form which does not appear to cross the Coast range. (Rhoads.) 
Osgood took an adult male at Cariboo Crossing, lat. 60°, B.C., 
June 26th, 1899; I took a female and two young 20 miles below 
Fort Selkirk, July 27th, and a young one near Dawson, August 
2nd. Osgood secured an adult and a young one at Camp David- 
son, August 5th and another was seen near Fort Yukon, Alaska, 
August 21st; all taken were in willows or alders close to the water. 
(Bishop.) I saw this species but once, on the 25th May, near our 
camp on the Kowak, Kotzebue sound, Alaska, but heard it a num- 
ber of times. (Grinnell.)
