Sitta canadensis Linnaeus. Red-breasted Nuthatch 



A red-breasted nuthatch heard calling in woods near Atlin on 

 June 5 was the only one of the species noted during the nesting 

 season. Next seen (a single bird) on Spruce Mountain, August 1. 

 During the latter part of August the species was ifligrating through 

 the woods near Atlin in fair abundance. Last seen by me on August 

 31, though it may be expected to occur in this region until a much 

 later date. 



Penthestes atricapillus septentrionalis (Harris) 

 Long-tailed Chickadee 

 Presumably resident in the region throughout the year, though not 

 abundant. Seen at Carcross during the last week of May, and about 

 Atlin during the whole of my stay, usually in poplar woods. Six 

 specimens were collected (August 16 to 28), all in fresh fall plumage 

 (nos. 44954-44959). 



Penthestes gambeli abbreviatus Grinnell 

 Short-tailed Mountain Chickadee 

 A male bird (no. 44960) in breeding condition was shot in spruce 

 woods near Atlin, June 12. Presumably the species nests in this gen- 

 eral region, but it was not otherwise observed. This is the northern- 

 most station at which it has been found. Grand Rapids, on the Stikine 

 River, 160 miles to the southward, being the nearest point of record 

 (Swarth, 1922, p. 297). • 



Penthestes hudsonicus columbianus (Rhoads). Columbian Chickadee 



A fairly common species in the Atlin region, more sO than the long- 

 tailed chickadee. Showed decided preference for spruce woods. 

 Twenty -three specimens were collected (nos. 44961-44983), comprising 

 six breeding adults, six juvenals, and three adults and eight immatures 

 in fresh fall plumage. 



The subspecies columbianus, described by Rhoads (1893, p. 23), 

 was included in the 1895 edition of the A. 0. U. Check-list, but it was 

 eliminated later (A. 0. U. Committee, 1908, p. 355) for reasons that 

 are not known to me. The series of birds above listed, together with 

 others from more southern points in British Columbia (see Swarth,
