RFI Barbary Dove - intentional feral relocation/release

["Wendy" <>]

        "So he was intending to release them just to see something new
flying
            around?  Cool, I wonder how many more there are like that?"

Many years ago I worked in a Victorian State Government office licensing
(mostly) native animal (mostly birds) keeping.
I fielded a call from an anonymous person one day wanting to know about
taking Song Thrushes (Turdus philonelos*) to Qld.
Why? He was moving there and liked their song.
I tried hard to dissuade him.
I doubted I succeeded, but hoped, if they don't already occur there, that
conditions are unfavourable and his, if he got them there, would not
survive.
They certainly occur, but don't proliferate around my area.
