CAGE AND SINr iNG BIRDS. 
SECTION II. 
SPECIES. 
It will bo most convenient for our present purpose to 
arrange t!;G birds on wliicli we have to treat in groups or 
families^ in accordance with their natural affinities, having* 
regard more particularly to the nature of their food, and 
mode of treatment in captivity. Any strict adherence to a 
merely scientific arrangement would scarcely be looked for in 
a work like this, and it would be objectionable for several 
reasons. 
Let us then proceed to describe our first family, that of 
the 
WARBLERS, 
Included by some naturalists in a distinct genus under the 
term sylvaa. These are all what are called insectivorous, or 
soft-billed birds, and are mostly only summer visitants in 
this country. Generally speaking they are very difficult to 
rear and keep in a state of captivity, and therefore require 
an extraordinary degree of care and attention. An eminently 
musical family of birds are these warblers i sweet feathered 
choristers are they all ^ but the sweetest of all, crowned by 
general consent as the very qiieen of song, is 
THE NIGHTINGALE. 
This is one which requires a very careful study of its 
wants and habits, and an exceedingly tender and delicate 
mode of treatment, to keep it healthy in a state of confine- 
ment. 
It is a migratory bird, and generally arrives in this country 
about the middle of April 5 the males preceding the feiTici]' :-
