List Categories
While we are on the subject of list categories, a suggestion has been made that we need to reconsider the category of those species which once seemed to be established exotics but have now disappeared, Chestnut Munia, Baya Weaver and perhaps Ring-necked Parakeet.
I like the idea of putting them in a sub-category of E (i.e. not part of the 'tickable' Hong Kong list) of species which formerly had a breeding population but not any more. UK list has a similar category. The reason for distinguishing from standard Cat E is a recognition that the species did, for a time, form an element of the Avifauna. I think a sub-cat of E is probably better than a sub-cat of D as this is where (e.g.) Yellow-cheeked Tit could end up if (when?) it disappears.
Any opinions?
