BOUREE'8 PABRAEEET. 
same remark applies to many other species of exotic birds, which can, 
it is true, survive the rigours of our climate, but would certainly thrive 
much better if duly protected from them. 
The western aviary at the ‘‘Zoo^’, is our beau-ideal of what an aviary 
should be; only we would have it all in one, a comfortable house at 
the back, where hot-water pipes maintained an equable temperature all 
the year round, and a spacious flight in front, well grassed, and planted 
with suitable trees and shrubs, with a limpid streamlet meandering 
through, in which the birds could drink and wash themselves at will, 
without risk of contaminating the water, and from which they could 
be shut off when necessary during the prevalence of frost or intem- 
perate winds. 
In such a place it should be the rule, and not the exception, for 
the birds to breed; and where, as in the case of the Parrakeets under 
consideration, the price of sundry species is high, the undertaking 
should be at least self-supporting, if, indeed, an actual profit were not 
obtained.
