Dear Dion
Thanks for some sensible clarity on this silly issue. For those who are
keen on lists, they can have a list for escapees, ship-assists, corpses and
whatever, even make a special note on rareties like the Blue Rock-thrush
which presumably did fly here by their own efforts and can be added to an
Oz list when approved by the holy rarety committee.
I remember well my excitement in my very early days in Australia finding a
pair of Bourke's Parrots with a juvenile in Centennial Park, Sydney, and my
chagrin when I learnt they were escapees and not OK for the list - had to
wait until I camped in Currawinya National Park, SW Queensland, before
adding them to my Ozzie list.
