BLACK-AND-WHITE CORMORANT 141 
are black. There are twelve feathers in the tail. 
The flanks are mostly white, under tail coverts black. 
The bird is little more than half the weight of the 
Large Black-and-white Cormorant. It dives almost 
as well as the Grebes and much better than any other 
Cormorant. 
DARTER 
Anhinga novce-hollandice 
Since the year 1892 I have not seen the Darter, but 
in that autumn, when we had many rare visitors to 
the River and Lakes, I observed three or four in a 
single day on the Barwon between Willows and Lakes. 
They were perched on the topmost branches of 
redgums by the river-side, giving, as I passed in a 
four-oar, a clear view of the long serpentine neck 
from which the bird is called Snake-bird by the 
dwellers in places where it is a common species. It is 
nearly related to the Cormorants, resembling the Large 
Black species most of all, but the great length of its 
neck prevents any possibility of confounding the two. 
It feeds, like the Cormorants, entirely or almost entirely 
on fish. The birds mentioned as observed in 1892 
probably came to us from Riverina. 
GANNET 
MoTUs serrator dyotti 
Most of us probably know the Gannet quite well 
by sight without recognising just what bird it is,
