Prosthemadera novaeseelandiae
New Zealand's native Tui .
It is almost black with an iridescent sheen and and has the most beautiful and distinguised birdsong of all our native birds.
In our colonial past it was referred to as the Parson bird because of the white tuft of feathers on the neck of the adult birds.
