This is a guide that came out a few years ago in conjuction with an exhibition on at the Otago Museum. It is a comprehensive guide to birds that live in Dunedin, New Zealand.
One of the descriptions is of the “Hen” which features the Port Chalmers population at Scott’s Memorial, a semi-feral colony which has become one of Dunedin’s many odd little features. Apparently the spot has established itself over the years as a drop off point for unwanted chicken (many of them are roosters). There have been controversial attempts to exterminate the established population, however judging by locals reactions to the attempts
I think the birds are likely to be there for some time to come.
