IV ANATIDAE eZee 
and “Old Squaw” in America; it flies very swiftly and nests near 
water, laying from six to twelve oblong grey-green eggs, 
Clangula glaucion, the Golden-Eye, not yet proved to breed in 
Britain, though it does so in North Germany, the Caucasus, 
Siberia, and Maine, besides the Arctic Regions generally, is found 
in winter to the Mediterranean, and thence to North India, China, 
Japan, Mexico, and Cuba. The glossy head is green, with a slight 
crest and white cheek-patches; the upper parts are black with 
white on the wings and scapulars, the lower surface being white, 
the bill black, the iris golden, the feet orange. The female has the 
head and back brown, the chest grey. Similar to Fuligula in 
general habits, the Rattlewing, as it is often termed from its noisy 
flight, is more partial to inland waters in winter, while for breed- 
ing it prefers hollow trees, or nest-boxes set up by Lapps and Finns, 
the ten or twelve eggs being bright green. (C. islandica, the ordi- 
nary species in Iceland, differing from C. glaucion in its purplish 
head, inhabits Arctic America also, and winters in the United 
States, rarely straying to Britain or the rest of Europe. C. albeola, 
the Buffel-head, of North America, which has visited the Com- 
mander Islands and Britain, has the head purplish-green with a 
large white occipital patch, the iris brown and the feet pinkish. 
It breeds to the northward, the eggs being whitish. 
Tachyeres cinereus, the Logger-head or Steamer Duck, of Chili, 
the Falklands, and Straits of Magellan, is grey in both sexes, 
with lighter head, rufous throat, white secondaries and _ belly, 
orange-yellow bill and feet. The narrow median rectrices are 
curled up, the wings very short; while the adults apparently lose 
the power of flight. Darwin well describes the noisy splashing 
action, the rapid and flapping swimming movements, the weak 
diving powers, the strong beak adapted for extracting shell-fish, 
and the voice like that of a bull-frog.t From seven to nine eggs 
are laid among herbage or low bushes. 
Fuligula marila, the Scaup, of Northern Europe, Asia, and 
America, which migrates to the Mediterranean and Black Seas, 
North India, China, and Guatemala, has the head, neck, and chest 
greenish-black, the back vermiculated with black and white,” the 
wings and tail dusky, the speculum and under parts white, the bill 
and feet plumbeous. The female is chiefly brown above, with

* Fine alternate dusky and white lines produce a grey effect at a short distance.
