Hi David and others,
I often joke when I hear that the Hunter Twitchaton teams tick the Shortland Magpie Geese that they are ‘captive-bred mongrel stock’ and are a questionable tick, as I understand that they were released there in the early 1980s. I was very disappointed with the release as it made monitoring the natural recolonisation of the state impossible.
They are tickable though if they have bred successfully locally which I suspect that they have.
