: TUFTED DUCK. 147 
cf the true Ducks. It does now however, ever stay to breed 
with us, and can have no further notice here. 
257. SURF SCOTER—(O:demia perspiciliata). 
_ A bird of very rare, and, perhaps also it may be added, very 
local occurrence. 
258. RED-CRESTED WHISTLING DUCK—(fuliguia rujina), 
Again another occasional vistor. 
259. POCHARD—(Fuligula ferina). 
Dunbird, Red-headed Wigeon, Red-headed Poker, Duncur.—A 
winter visitor, and in very considerable numbers in districts 
where the presence of inland waters to a sufficient extent enables 
‘ them to follow out their natural habits. It is almost impossible, 
from their great quickness and skill in diving, to take them with 
the other ‘‘ Fowl” in the Decoy, and they are therefore captured by 
a peculiar arrangement of nets affixed to poles so heavily weighted 
at one end as on being liberated to elevate the net in such a way 
as to intercept the flight of the birds, as soon as they are fairly on 
wing. The Dunbird does not now breed in this country. 
260. FERRUGINOUS DUCK—(fuligula nyroca). 
Somewhat resembling the Pochard in general hue, but smaller, 
and in respect of the numbers in which it has been met with in 
this country, comparatively a very rare visitor. 
261. SCAUP DUCK—(Fuligula marila). 
Spoon-bill Duck.—A winter visitor, and not an unusual one, 
although its numbers are never such as to commend it to notice 
in the same way as the Wild Duck, the Dunbird, the Wigeon, and 
some others. It breeds commonly in Iceland, but never in Britain. 
262. TUFTED DUCK—(fuligula cristata). 
Another constant winter visitor, and as well or better known 
than the Scaup. Like the Scaup Duck it usually prefers oozy 
or muddy estuaries and their customary accompaniments. But
