) GARDEN AND AVIARY BIRDS. 
find numbers of green Parrots with long, pointed tails, 
and if we watch the domestic affairs of these we shall 
discover that their young, as a rule, preserve the same 
type. All these birds, therefore, we group as a species, 
called in English the Rose-ringed Parrakeet, from the 
pink ring on the neck of the males. In some places we 
shall come across a smaller Parrakeet, of the same general 
shape, but with the head of a strikingly different colour 
from the body—plum-colour in the male and dull purple 
in the female. If we attend to the propagation of 
these we shall discover that their young in turn resemble 
them, although the coloured head takes some time to 
develop. These, then, form another species, called the 
Plum-headed Parrakeet. 
Further research will show us yet other kinds, all agree- 
ing in general shape, but differing slightly in propor- 
tions, and morein colour. We group all these together 
as a genus; in popular language, they are all birds of 
the same style, though each species, or collection of in- 
dividuals, differs in certain details which are peculiar to it. 
If we examine the Parrakeets brought from Australia, 
we shall observe that while they can be divided up into 
groups of individuals, forming species, which groups 
differ in colour even more strikingly than our Indian 
birds, yet many of them agree closely in certain details 
which mark them off as another group or genus. Thus, 
though their tails are long and pointed, they are very 
much shorter and broader than those of the Indian 
Parrakeets ; their legs are longer, and, if we come to keep’ 
and observe them. we shall find their movements are
