Apart from well-domesticated
bird species, keeping birds in
aviaries is obviously preferred
whenever possible. The aviary,
usually being larger than most
cages, allows birds far more exercise
and this usually accounts for
healthier birds. However, even
aviaries must be carefully considered
for their suitability for the
species or group of birds that
are to be housed.
There are many books
on the subject such as The
Cage & Aviary Bird Handbook.
Aviaries are usually preferred
where breeding of wild bird species
is contemplated.
