Using this vocalisation to locate breeding females using Automatic Acoustic Devices and visual spectrogram analysis is a useful research tool c.

I had a Pāteke disturb monitoring this morning...just popped out of the wetland and waddled on through the ngāhere! Not concerned at all by the human sitting up in the tree a metre or so above it! Pāteke or Brown Teal are 'Nationally increasing' but remain 'Conservation Dependent', meaning the population needs ongoing support to recover and is still vulnerable to threats like predation and habitat loss. Pāteke need wetlands too...when we restore Habitat for Hūrepo we help other wetland dependent
