Io BLACK-THROATED THRUSH. 
4,000 feet, and probably in the valley of the Ob; and although 
too late for eggs, the late Mr. Seebohm obtained three young not 
fully-fledged in the valley of the Yenesei between 60° and 63° N. 
lat., early in August. Herr Tancré’s collectors have obtained a 
series of eggs in the Altai Mountains which “exhibit the same 
variation in colour as the eggs of the Blackbird, and measure from 
12 to 1°rs in. in length, and from ‘8 to 75 in. in breadth” (See- 
bohm). This Thrush winters in Northern Persia, Afghanistan, 
Turkestan, Baluchistan, and India, as far south as Assam ; its range 
extending eastward to Lake Baikal. There it meets with the Red- 
throated Thrush, 7: vuficollis, a species which has wandered to 
Heligoland and Saxony. 
The food of this species is stated by Dr. Scully to consist in 
winter chiefly of the berries of Zveagnus, a diet varied with 
insects and worms. Favourite haunts in the cold season are sand- 
hills, low scrub, and trees bordering watercourses ; while Seebohm 
found that in summer a marked preference was shown for pine- 
trees, and the neighbourhood of the banks of the river where the 
forest had been cut down for fuel. The song of this species is 
undescribed. 
The adult male in breeding-plumage has the throat and breast 
black ; belly white, turning to greyish-brown on the sides and flanks ; 
upper parts olive-brown, darker on the wings and tail. In winter 
the throat-feathers have light margins, and the general plumage is 
duller. The young male resembles the adult female, in which the 
feathers of the throat and breast are not completely black, but have 
merely dark centres, forming a streaked gorget; under parts dull 
creamy-white. In both sexes the under-wing and azxillaries are 
golden-buff. Bill dark brown above, pale below ; legs and feet pale 
brown. Length about 9°75 in., wing 5°45 in. 
Turdus migratorius, commonly called in North America ‘the 
Robin,’ owing to its ruddy breast, has been obtained at Dover; 
but, like the Wydah-bird and other exotic species obtained in that 
locality, it had probably escaped from some ship passing through 
the narrow seas. An example taken near Dublin in May 1891, and 
another from Leitrim, Dec. 1894, are both in the Dublin Museum, 
while one was obtained alive near Leicester in Oct. 1893. The 
species has occurred once at Heligoland, on the high road of vessels 
for Bremen and Hamburg; and it is not unfrequently brought to 
Europe as a cage-bird.
