Quite apart from the official country bird list, what is the definition for
including birds in field guides. Along the same lines as Edwin, it has always
concerned me that birds such as Muscovy and even Khaki Campbell are not
included in local field guides despite the fact that you see them regularly in
the "field". For example there is a very large Campbell hybrid at Banyule
Wetlands at the moment. An experienced bird watcher can identify this bird
however someone solely reliant on a field guide would be stumped.
To include information on domestic 'field' birds would only take an additional
page or two and reference could be made to the fact that they are unable to
"establish themself and breed regularly as wild birds and reproduce within the
new habitat."

Bird (or plants) would be added to a countrys bird list or flora list when they
become naturalised that is they are able to establish themself and breed
regularly as wild birds and reproduce within the new habitat.

Could anyone comment on this in response to a query someone had recently.
When do you think we can know count feral Guinea Fowl, Greylag Goose,
Muscovy Ducks on our Oz lists? These have become established in some places
around Sydney. What are the rules for adding introduced birds to our list if
we say we can count Mute Swans, Peafowl, Red-whiskered Bulbuls etc?
