196 THE LONG-TAILED DUCK OR ‘CALLOO’ 
the tinkling of bells, whence the German name die Schelle Ente, 
Bell Duck, the Norfolk provincial name Rattle-Wing, and the 
systematic name Clangula. The young male does not make this 
noise, and having also desig plumage from the adult, has been 
described by some authors as a distinct species under the name of 
Morillon. 
The food of the Golden Eye varies with its haunts. In estuaries 
it feeds on crustaceous and molluscous animals and small fish, which 
it obtains by diving. In rivers and lakes it feeds principally on 
the larve and pupz of insects, for which also it dives in clear deep 
water. The call-note is an unmelodious quack or croak. 
The Golden Eye breeds only in high latitudes, and builds its nest 
in holes of trees, often at the height of twelve or fifteen feet from 
the water, into which it has been seen to convey its young one by 
one, holding them under the bill, and supported on its neck. The 
Lapps, in order to supply themselves with eggs, are in the habit 
of placing in the trees, on the banks of the rivers and lakes fre- 
quented by these birds, boxes with an entrance hole, which, though 
invariably robbed, are visited again and again. 
The Golden Eye is found in many countries of Europe, in Northern 
Asia, and in North America,

upper plumage generally dark brown, under white. Length sixteen 
inches. Eggs greenish white, tinged with buff. 
THOUGH a few specimens of this beautiful bird are obtained from 
time to time in various parts of England, especially on the coast 
of the eastern counties, it cannot be considered other than a rarity. 
‘Among the northern islands of Scotland, and along the coasts of 
the mainland’, Macgillivray tells us, ‘ these birds make their appear- 
ance in October, in small flocks, which gradually enlarge by the 
accession of new families. In the Bay of Cromarty, where they are 
very common, it is pleasant to see them in small flocks scattered 
over the water. They are most expert swimmers, and live on 
bivalve shellfish and crustacea, which they obtain by diving in 
shallow or moderately deep water. The male in swimming raises 
his tail obliquely, in rough water almost erects it, and is remarkable
