Are these regular New Zealand wildlife sounds (listen with headphones below)? I have had bi-pedal approaches and found varying footprints among other things here in an area restricted to the general public. Samples originate from captures on my point-of-view camera audio mic. If anyone please can identify what animal they come from please contact me. I have amplified via software. One of the sounds I heard for about 15 minutes and also heard on occasion about a year ago in the lower ravine area. Audio recorded with video on December 29, 2019 from an undisclosed research area.
The footprint video below is very close to where I caught one of the sounds
