Churchill. These proved to be intermediate between novaboracen- 
‘sts and notabilis, but nearer to notabilis. (EL. A. Prebles.) Two 
specimens from Chemawawin, near Grand Rapids of the Sas- 
katchewan, agree more nearly with the species than with S. xova- 
boracensis notabilis. (Nutting.) A specimen of this species was 
secured in August west of ,the Sweet Grass Hills, on the head- 
waters of the Milk River. It was again observed in the under- 
growth surrounding some reedy pools near Chief Mountain. 
(Coues.) A summer resident along watercourses in Manitoba. 
They were very abundant at Humphrey’s Lake on August gth, 
1884. Evidently preparing to migrate. (Zhompson-Seton.) A 
common summer resident at Avenue, Manitoba, arriving about 
May 13th and leaving late in September. (Norman Criddle.) 
This is an abundant spring migrant at Indian Head, Assa., 
the first individual seen was on May 11th, they became common 
at once and were abundant in spring for a few days along streams 
and shores of lakes; one specimen seen at Edmonton, May 15th, 
1897, evidently a migrant; common from the mouth of Lesser 
Slave River to Peace River Landing, in Lat. 56° 15’, June, 1903; 
breeding around Vermilion Lakes at Banff, Rocky Mountains, 
July, 1891, rather scarce; one seen on the International Boundary 
near Rossland, in May, 1902. (Spreadborough.) This bird was 
only seen at Carlton House where it frequented the moist and 
thickly wooded points of the river, It arrived in May and dis- 
appeared in a few days, probably going further north to breed. 
(Richardson.) North to Lapierre’s House, on the Mackenzie 
River; common. (Ross.) Two specimens were taken at Duck’s, 
August 7th and gth, 1889. (Séreator.) Found breeding along 
interior streams of British Columbia; Lac la Hache and Bonaparte 
River. (Rhoads.) Breeding at Quesnel, B. C., and less commonly 
at 158-Mile House. (Svooks.) 
The barren coast of Behring Sea from the mouth of the Yukon 
north and south affords it but little shelter in the spring, hence 
its extreme rarity there in spring. It occurs in spring where the 
dense growth of bushes about Kotzebue Sound affords it available 
breeding grounds. It is, in fact, one of the commonest bush- 
frequenting birds we have in the north. (WVe/son.) Several spect- 
mens of this bird were obtained at St. Michael in August, 1876. 
I have never observed it there during the breeding season. 
(Turner.) The first sound that I heard on the morning of August
