The visits of this bird are very infrequent, and its appearance not 
to be depended upon.

This bird must be considered among our accidental visitors.

Formerly a common stationary form in our marshes and fens; now 
seldom seen, and mostly in winter.

The frequent occurrence of this bird in the British Islands de- 
mands a place for it in our ayifauna; and hence I have given a 
figure of it.

Lirrite Brirrern. 
Although never to be found with certainty, it is probable that we 
are seldom without the presence of this interesting marsh-lover: 
it cannot, however, be considered other than a chance visitor. 
Family CICONIIDA. 
This family includes among its members not only our weil- 
known White and Black Storks, but at least twenty other species 
of those useful birds. Whatever the condition of Britain may formerly 
haye been, it is no longer suited as a resting-place for either of the 
two species just mentioned ; still scarcely a year passes without one 
or other of them accidentally dropping down on our marshes during 
their wanderings from one country to another.
