* T. fuscatus is the most common Thrush in the country of the Amour, where it is to be seen in large 
bands in autumn. The first I saw, probably on their way from the north, were met with on the 
19th of September at the village of Belgou, near the mouth of the Gorin. Іп 1854 I observed some 
at the Nikolaiewsk Post between the 166 and the 26th of October, between which dates considerable 
flocks were making a great uproar on the larches at the edge of the forests growing along the 
course of the river and its little tributaries, the Karm, Litscha, and Patscha. At the end of this 
period solitary individuals were mostly observed, and the last were noticed on the 26th. M. Maxi- 
mowicz has also killed a bird at the Marinsk Post on the 25th of October. On the 26th of September 
I obtained from M. Maack a specimen from the Boureia Mountains." 
Przewalski observed the first arrivals in spring on Lake Khanka on the 24th of April in 1868, 
and on the 21st of April in 1869. | | 
Nikolski gives the following note :—“ If this species nests at all in Sakhalin, it is probably only 
in the northern parts of the island. During my stay in the central part I never met with the bird 
in summer, and Poljakow collected his specimens during the spring and autumn migrations, both on 
the east and west sides of the island. In the notes found after his death he states that he often met 
with the species in the first half of June in the valley of the river Sousoi: it made its appearance 
in the island at the end of the spring, and was seen in the autumn when the snow commenced. 
On the 15th of October [O. S.], when he obtained one specimen, the temperature was considerably 
below zero, the trees and bushes were all turned yellow, and some of them were bare of leaves. 
MM. Dobrotworski and Mitsoul indicate this Ouzel as being very common in the south of the 
island, but do not state whether it nests or is only a bird of passage." 
In the Seebohm Collection is a fine series of this Ouzel obtained by the brothers Doerries at the 
mouth of the Amur River between October and April, as well as one specimen of Dybowski's from 
Sidemi in Ussuriland. 
Middendorff did not meet with the present species on the Stanovoi Mountains, bnt he says that 
he shot some specimens on the Yenesei above 59° N. lat. in the coldest part of the winter (Reis. 
Sibir., Zool. ii. p. 172, 1851). On the latter river Seebohm says that it was the first Thrush to arrive 
at the Arctic Circle, small parties coming in on the 4th of June. Не writes (Ibis, 1879, р. 3):— 
“They were to be found feeding on the steep banks where the sun had melted the snow. Their 
call-note reminded me of that of the Redwing. During the next week they were very plentiful, and 
I began anxiously to look out for their nests; but within a fortnight of their arrival they had all 
disappeared, and I saw no more of them until the 12th of July, during our voyage down the river. 
On this day we cast anchor for a few hours in lat. 69?, and I went on shore to explore for the first 
time a Siberian tundra. I climbed up the steep bank, and found myself in a wild desolate-looking 
country, full of lakes, swamps, and rivers, in some places a dead flat, in others undulating, and even 
hilly, brilliant with gay flowers, swarming with mosquitoes, and full of birds. In sheltered places 
dwarf willows and creeping-birches were growing, and (because we were only some fifty versts from 
the forests) here and there a few stunted larches. Winding through the tundra was the bed of a 
rver, now nothing but a small deep valley, forming a chain of isolated lakes and pools. This 
river-bed bears the name of the dried-up Doo-din'-ka, and is about fifty versts to the north-west of 
the real river Doo-din'-ka. Оп some of the northern slopes large patches of snow were still lying, 
Most of the birds evidently had young. 1 found myself generally the centre of attraction of a little 
crowd of birds uttering their various alarm-notes as they flew round or waited on some shrub 9% 
plant with their bills full of mosquitoes, anxious to feed their young as soon as I was out of their 
way. As I was returning to the shore, and descending a steep sloping bank covered with patches
