season. The speckled upper surface of the body and the 
dusky streaks on the axillaries distinguish C. septentrionahs in 
winter. 
Range in Great Britain.-This species breeds in Scotland from 
Argyleshire northwards, as well as in the Hebrides and the 
Orkney and Shetland Isles. “ In Ireland, says Mr. Usshe^ 
“ one OT two pairs have been discovered to breed on mountain 
likes in Donegal, but as their eggs are regularly taken foi 
collectors, the birds, if not s® 
away. A pair may have bred m Sligo (Zool. 1890, p. 35 )• 
In winter tL Red-throated Diver is found on all the coasts of 
Great Britain, and not only ascends estuaries, but is sometimes 
observed far inland. , 
Range outaide the British Islands.-The present species has a 
circumpolar distribution during the breeding season, and has 
been found as far north as 82 N. lat. In winter it visits the 
Mediterranean, Black and Caspian Seas, and m Eastern Asia 
is known to occur in Japan, China, and Formosa. In America 
it migrates in winter across nearly the whole of the United 
States 
Hahits.— I am indebted to my friend, Mr. W. R. Ogilvie 
Grant, for the following interesting note on the species 
“ In the north of Scotland I have, on many occasions, had 
opportunities of watching the breeding habits of the Red- 
throated Diver, and in May of 1896 I spent several whole dajs m 
observing the behaviour of a pair who had a "est with two 
partially incubated eggs on the edge of a small loch. T 
species almost invariably selects the small desolate lochs, 
often mere pools, situated in the more lo'^^ly and deserted 
parts for purposes of nidification. In the north of Suther 
land,’ where the country is a mass of lochs of every size and 
shape, there is much ground eminently suited to the habits 
of this Diver, but for some reason only a few scattered pairs 
avail themselves of this fine tract of country. T le two eggs 
are always placed close to the water’s edge, . 
margin of the loch, or on some tiny islet where the bank mes 
at a very gentle slope above the surface of the water. ^sse 
birds are so curiously constructed — the legs being placed so 
far back on the long boat-shaped body — that, though admira y
