Tracking A Tiny Kiwi Chick In The Wild
- Lauren Sommer joined Fakatani Kiwi Trust to locate a five-week-old kiwi chick using a radio transmitter.
- The team found a tiny North Island brown kiwi and performed a health check before releasing it to the wild.
Stoats Drive Kiwi Mortality
- Young kiwi survival is extremely low, around 5%, primarily due to stoat predation.
- Stoats were introduced to control rabbits but became efficient killers of native birds instead.
Local Groups Use Humane Mesh Traps
- Whakatane Kiwi Trust uses DOC 200-style mesh traps with a crushing bar to kill stoats instantly.
- Traps passed animal welfare testing and hundreds are deployed to protect kiwi populations.
