Townsend 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 everywhere in the woods. In August they became very scarce, so 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. Hleven 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 Stikine 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
