New Zealand Scaup

Aythya novaeseelandiae

Male - Rotorua, New Zealand - November 2005

New Zealand Scaup is endemic to New Zealand with a population of around 20,000 birds.

Female - Rotorua, New Zealand - November 2005

Female - Tasmania, Australia - November 2016

The female above is extralimital and I've been reliably informed that it was a known escape from a wildfowl collection across the river.
