THE TUETED DUCK. 
White-sided Diver. 
Fuligula cristata, Steph. 
Anas fuligula , Linn. 
Is a regular winter visitant. 
Accoeding to the testimony of an experienced fowler, it is the 
latest of the Fuligulcs arriving in Belfast Bay ; even the month 
of December, in which he killed the first birds seen by him there 
in 1839 and^.1840, being considered early. On fresh water, 
to which these dncks are partial, they appear earlier ; — in the 
middle of November I have observed them on Bally drain Lake, 
and have received specimens from Lough Neagh, among which 
were adult males, as well as young birds. They have frequently 
been brought to me from the latter locality from this period until 
April ; December and January being the months in which they 
were chiefly procured. But I have known them to remain there 
until May, on the 4th of which I saw one, in 1850. 
At the beautiful sheet of water — Ballydrain Lake — this species 
is seen to great advantage. The following one or two notes made 
by a friend relate to it there : — When the lake was frozen over on 
the 27th of January, 1833, in addition to a few wild ducks and teal, 
a number of tufted ducks (of which some were old males) appeared 
in company with pochards. During Eebruary, the tufted ducks con- 
tinued there ; and on the 3rd of March, a very warm day for the 
season, “ twenty-six males, with fine crests and pure white sides, 
and twenty-five females with apparently no crests, brownish sides, 
and generally of a brownish-black colour, were congregated toge- 
ther.” Above a dozen of pochards, too, appeared, with their 
bills concealed amid their dorsal plumage, — a favourite position 
of the Fuligulce , when quietly resting on the calm waters of the 
inland lake or of the sea by day at full tide, in particular, they 
are generally thus seen, sleeping, or enjoying their rest after the 
toil of flight and feeding during the preceding night. There
