Myadestes townsendi (Audubon). Townseud Solitaire 



Extremely rare, though as one was seen in Kispiox Valley on 

 June 24, the species probably breeds in the region. Others seen on 

 September 2, September 13 (two birds), and September 17, make up 

 the total of observations. One specimen collected (no. 42594), an 

 immature male taken in Kispiox Valley on September 2. 



Hylocichla ustulata swainsoni (Tschudi). Olive-backed Thrush 



Common in the lowlands; not seen at high altitudes. The first 

 arrival was heard singing on June 1 ; on June 3 olive-backed thrushes 

 were everj'where in the woods. In August they became very scarce, 

 SQ much so that none was seen for some weeks and I supposed they 

 had already gone south. Then, the last week in August a few re- 

 appeared, and, while not abundant, one or two were seen almost daily ■ 

 until late in September. The last was noted on September 21. Eleven 

 specimens collected (nos. 42595-42605), six adult males, two adult 

 females, and three immature males in first winter plumage. 



Hylocichla guttata guttata (Pallas). Alaska Hermit Thrush 



There were a few hermit thrushes on Nine-mile Mountain, breeding 

 in the spruce and hemlock forest immediately below timber line. The 

 song was heard occasionally and at longer intervals a glimpse was 

 caught of one of the birds flitting through the dense shrubbery. Two 

 specimens collected (nos. 42606-42607), both adult males, taken on 

 July 29 and August 10, respectively. They are essentially like breed- 

 ing birds from the upper Stikjne River, and, as with the latter series, 

 are not to be referred to Hylocichla guttata sequoiensis, a name that 

 has been applied to the hermit thrush of this general region (see 

 Swarth, 1922, p. 303). 



Hylocichla guttata pallasi (Cabanis). Eastern Hermit Thrush 



During the second week in September a very few migrating hermit 

 thrushes appeared in the woods of Kispiox Valley. Two were shot 

 September 10, and others seen up to September 14. The two collected 

 (nos. 42606, 42607), both immature males in first winter plumage, are 

 obviously not the same as the breeding bird of this region, and appear 

 to be best referred to the eastern subspecies, Hylocichla guttata pallasi. 

 They are not so bright reddish dorsally as are most eastern specimens, 

 but they are distinctly more reddish than guttata, they are larger than 

 guttata, and they have the buffy flanks of pallasi. The subspecies
