in Germany, and it has also been obtained once in Holland, near Haarlem. Dr. Dubois (Bull. Mus. 
Belgique, v. p. 99, 1887) records a young bird as having been taken near Brussels in October 1886. 
It has also been supposed to have been seen in Heligoland, but no specimen was procured (Seebohm, 
Ibis, 1892, p. 7). 
Mr. Seebohm contributed the following note to Mr. Dresser’s ‘ Birds of Europe’:—“ The Dark 
Thrush arrived on the Arctic Circle on the 7th June, and frequented the oases of bare ground on 
the sunny slopes of the banks of the Koo-ray'-i-ka, where it fed upon the previous year's crowberries 
and cranberries which had been preserved through the winter by the frost. As soon as the snow 
in the forests was melted, these birds left our headquarters and retired inland to breed. 1 secured 
several examples on their first arrival, and afterwards frequently heard their song in the forests. 
This Thrush is a very poor songster, but he has a splendid voice. Не seldom gets beyond two 
or three notes; but in clearness and richness of tone the few he utters are fully equal to those 
of the Blackbird. On the 27th June, a day or two before we left the Koo-ray'-i-ka, as I was 
strolling through the forest extremely annoyed at what I thought was the unreasonable delay 
of Capt. Wiggins in starting for the tundra, I suddenly forgot all my troubles by seeing a 
Dark Thrush fly from her nest in a slender spruce fir-tree. I shot the bird, and was soon up 
the tree. Тһе nest was placed about fifteen feet from the ground, upon a horizontal branch 
about six inches from the main stem. It was exactly like that of a Fieldfare, but was carefully 
lined with mud before the final lining of dry grass was placed in it. It contained five eggs 
resembling small but richly-marked Blackbird's eggs. 
“ After we left the Arctic Circle, I saw no more of this species until the 3rd of August, on my 
return journey, when, in lat. 66%, near Sil-o-vah'noff, the village of the unfortunate Scopsi, I shot a 
young Dark Thrush in first plumage. On the 6th of August, in lat. 63°, I got amongst а brood 
of young Dark Thrushes, which were uttering loud cries like tick, tick. This, I presume, is the 
Kestrel-like cry alluded to by Latham. I shot one bird from this brood." 
Mr. H. L. Popham, who also found the species breeding on the Yenesei River, observes :— 
“This Thrush has a fine clear voice: he begins his song with a few rich notes, which are not very 
much varied, and goes off with the same style of ending as in a Blackbird's song. Three nests 
of this Thrush were found, resembling those of the Fieldfare in construction, at Inbatskaya 
(lat. 64” N.): one about four feet from the ground on a stump, and another built close to the stem 
of a fir-tree, on a branch about twenty feet high. The eggs are smaller than any of the other 
Thrushes’ eggs found by us, and average 1:06 inch long by 75 inch broad" (Ibis, 1898, p. 493). 
Mr. Dresser (Ibis, 1901, p. 445, pl. ix. figs. 5-8) has described and figured some of Mr. Popham's 
eggs from the Yenesei, and he observes:—“ The number of eggs is four or five, seldom six, 
and they are smaller than any of the other Siberian Thrushes, averaging 1:06 by 0:75 inch. They 
are also less subject to variation, and are somewhat darker and more blue in ground-colour. One 
clutch is rather of the Blackbird type, but the rest are more or less spotted and blotched with 
rusty-red. Тһе nest is like that of a Fieldfare, strongly built, and lined with fine grass and dry 
larch-needles." 
Mr. Dresser's work also contains the following translation of Dr. Dybowski's notes on this 
species :—“ This Thrush breeds here (in Dauria) and is tolerably common, appearing in the spring 
about the 20th May. During the nesting-season it inhabits valleys overgrown with larch, fir, and 
the Cembra pine. It nests on young free-growing fir or larch trees, the nest being placed in 
а fork or on the boughs near the main stem, at an altitude of about 3 to 5 metres. It is constructed 
of dried grasses and weeds, worked together with earth and lined with fine grass and dry larch- 
needles, and is neatly and firmly built. It measures 120 millims. outside diameter, and 100 millims.
