Up First from NPR – "Kiwi vs. Predator" (Oct 26, 2025)

The Sunday Story with Ayesha Rascoe

Episode Overview

In this Sunday Story edition of NPR’s "Up First," host Ayesha Rascoe and NPR climate correspondent Lauren Sommer explore New Zealand’s bold, controversial campaign to save its unique wildlife by eradicating invasive species—especially for the beloved but endangered kiwi bird. The episode investigates the ethical dilemmas, technological challenges, and community mobilization at the heart of the "Predator Free 2050" initiative, providing an on-the-ground look at New Zealand’s efforts and the global implications for conservation.

Key Discussion Points & Insights

1. New Zealand’s Endangered Wildlife and the Predator Problem

• Volunteering for Conservation (00:41–02:28)

  • Lauren meets student volunteers Mila McKenzie and Finn Hibbert in Dunedin, planting trees and setting traps for invasive species.
  • Their group, Town Belt Kaitiaki, is part of the nationwide effort—Predator Free 2050, aiming to eradicate non-native predators by 2050, funded by the government and backed by volunteers.
  • Quote: "These are traps… trapping and killing animals that aren't supposed to be in New Zealand…so these invasive species have been devastating for native wildlife, especially birds. More than sixty bird species have gone extinct." – Lauren Sommer (01:25–02:28)

• Magnitude of the Task

  • Estimates run into tens of millions of invasive animals targeted.
  • Raises the question: Is such eradication even possible?

2. The Iconic Kiwi and Its Perilous Situation

• Kiwi’s Symbolic and Real Vulnerability (05:19–06:16)

  • The kiwi—national symbol and namesake for New Zealanders—is rarely seen due to being nocturnal and increasingly scarce.
    • Quote: “It’s really unusual and it's got a lot of attitude… once you see them you just love them.” – Claire Travers, Whakatane Kiwi Trust (05:45–05:54)
  • Rascoe reacts to the odd, endearing appearance of the kiwi.

• Fieldwork: Finding a Kiwi Chick (06:16–08:28)

  • Lauren joins a team tracking a five-week-old kiwi chick with a radio transmitter.
  • Only about 5% of chicks survive, mainly due to stoats—aggressive, invasive predators.

3. The Stoat: Small Predator, Big Threat

• Stoats as “Killing Machines” (08:28–09:23)

  • Stoats, related to weasels, are described by experts as "apex predators… one of the most amazing carnivores on Earth” and “absolutely amazing killing machines." (08:45–09:05)
  • Originally imported to control rabbits, stoats devastated native birds instead.

• Evolutionary Mismatch (09:49–10:33)

  • New Zealand’s flightless birds never evolved defenses against ground predators.
  • “When you freeze…it’s like when you fall in a horror movie, then they can really get you now you are the perfect prey." – Ayesha Rascoe (10:27–10:33)

• Emotional Toll (10:33–11:01)

  • Conservationists often find the remains of tagged kiwi chicks—"that's the heartbreak for me.” – Claire Travers (10:48–11:01)

4. The Methods: Traps, Fences, and the Challenge of Scale

• Trapping Stoats: A Grim Necessity (11:01–12:28)

  • Lauren observes humane but lethal traps; only a few “hardcore” stoats remain after years of trapping because they learn to avoid traps.

  • Quote: “Each stoat is a little victory…it’s a huge victory, really, because they are such hard animals to capture.” – Gay Pace, Predator Control Coordinator (11:54–12:03)

  • The goal: eradicate stoats, weasels, ferrets, and three rat species nationwide.

• Ethical Debate & Public Opinion (13:25–15:17)

  • Emily Park, University of Auckland ethicist, explains “Predator Free NZ is as much a social challenge as biological…reframing our cultural ideas of these kind of cute fuzzy mammals.”
  • Public and indigenous support is strong, with general agreement that humans must fix a problem they created.
  • Animal rights groups advocate for non-lethal controls but acknowledge necessity of intervention.

5. Alternatives to Nationwide Eradication

• Eco-sanctuaries ("Jurassic Park" Fences) (15:37–20:22)

  • The Orokonui Ecosanctuary uses six-foot-tall, electrified fences to protect native wildlife by keeping predators out.
  • The cost and maintenance are high, but within, birdlife can thrive.
    • Quote: “Ecosanctuaries aren’t cheap—they cost millions of dollars but some people think they’re a better value.” – Lauren Sommer (20:28–20:35)
  • Maori cultural value: sanctuaries preserve not just species, but stories and heritage.

• Setbacks and Costs

  • Invasive stoats have breached fences after storms, causing devastating losses.
  • Full nationwide eradication estimated to cost over $100 million per year (21:27–21:59).

6. Can Predator-Free 2050 Succeed?

• Skepticism and Hope (22:06–22:39)

  • Scientists are doubtful full eradication is feasible without major technological advances, but even population reduction helps.

• New Technologies

  • AI-powered traps that identify species before activating and can self-reset.

  • Early-stage genetic modification proposals (e.g., gene drives to reduce invasive populations), which raise serious ethical and ecological debate.

    • Quote: “Genetic modification definitely would come with a lot of concerns…and going back to Jurassic Park, they say nature finds a way. Are there risks to doing that strategy?” – Ayesha Rascoe (23:31–23:42)

7. The Global Takeaway & Closing Reflections

• Urgency and Uncertainty (24:04–24:51)

  • Climate change and biodiversity loss are worsening; the world faces the same questions as New Zealand: “How far should we go? How much should we do? There’s this shrinking amount of time to figure it out.” – Lauren Sommer (24:21–24:51)

• Key Closing Thought

  • “Even if they don’t think they can get there, the important thing is to try.” – Lauren Sommer (24:51)

Tone and Language

The episode maintains an accessible, engaging, and conversational tone, mixing scientific rigor with personal anecdotes and humor (references to Jurassic Park, “hardcore stoats,” giant chickens). The language is empathetic both towards animals and the humans involved, highlighting emotional stakes along with ecological facts.

Summary Takeaway

New Zealand’s fight to save the kiwi and countless other unique species through ambitious predator control is a story of community action, ethical quandaries, scientific innovation, and cultural values. Whether Predator Free 2050 succeeds or not, its lessons are globally resonant: conservation is as much about people and choices as it is about wildlife, and the clock is ticking for action in the face of biodiversity crisis.
