I thought it was built to keep rabbits out?

We shouldn't introduce species deliberately in new places, but in many places species have taken off and should be accepted.
A lot of bird species in NZ are unique and only found here. They're almost all critically endangered or at risk [1], as they evolved with no natural predators.
I'd rather we try and control these introduced species so we can keep (at least some of) our native birds.

(I shouldn't need to say this, but this is a joke and should not be taken as environmental policy :) )
