We saw a Kiwi baby at the Heaphy Track.
It was standing right next to the track at about 9:30 am.
It didn't appear sick, rather just lost a bit. After seeing us, it ran around a bit, stumbled onto the track and finally hid into a hole under some roots.
It didn't wear any visible marker or ring around the legs.
Its size was approximately 15cm length plus the beel.
