Whio (blue duck)
Status: nationally endangered
Throughout New Zealand, whio numbers have been in decline, because of stoat predation of nesting females and eggs.
At the Wangapeka/Fyfe, Oparara/Ugly and Arthur/Clinton/Cleddau river sites, numbers have increased from 16 pairs in the last three years to 49 pairs.
