it is a social bird, many pairs nesting in a small 
area, and collecting at certain spots to feed. © Its 
breeding-grounds are on the Arctic tundras, near 
the rush-and-grass-fringed lakes, amidst the thickets 
of birches, junipers, and willows. The nest is 
placed under a bush, or amongst herbage on a 
bank, and is merely a hollow lined with dry grass 
and sedge and dead leaves. To this, however, the 
usual lining of down is added. The eggs, from 
six to nine in number, are greenish-gray, and of 
smooth texture. The female, as usual, takes sole 
charge of the young. The Scaup Duck inhabits, 
during summer, the Arctic regions of Europe, Asia, 
and America, drawing southwards in winter almost 
to the tropics.

Tufted Duck derives its name from the bushy crest 
or tuft of feathers growing from the top of the head, 
and drooping down over the back of the neck on 
the male. The head, neck, and crest are glossy 
black, shot with purple and green; the upper parts, 
the breast and the under tail coverts, are black ; the 
remainder of the underparts and the alar speculum
