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. {E. T. Seton.) First seen at Aweme, 

 Manitoba, on May 12th, 1903, was common on the 17th and dis- 

 appeared on September i6th. A common breeding species. (Grid- 

 dle.) This is a rare summer migrant at Indian Head, Sask. It was 

 first seen at Indian Head, May 20th, 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. (Macfarlane.) 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. 

 (Str eater.) 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 2 1 St; 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.)
