Key Takeaways
- ✓Decoy colony technique: Conservation teams use painted concrete bird replicas combined with looped audio recordings to attract real seabirds to target locations. The Mana Island gannet project ran for nearly 20 years before attracting a single real bird, demonstrating that this proven method requires extreme patience and may still fail in specific geographic contexts.
- ✓Pioneer bird dependency: New gannet colonies cannot establish without a "first bird" willing to break from existing overcrowded colonies. Gannet populations biologically rely on a minority of individuals with higher exploratory drive. Without these outlier birds, species remain locked to existing sites, making their survival critical to long-term population distribution and resilience.
- ✓Habitat suitability variables: Even after a pioneer bird arrives and additional birds briefly follow, colonies can fail if fishing grounds are too distant, coastal aspect is unfavorable, or other site-specific factors are misaligned. Conservationists on Mana Island identified these variables as likely reasons three visiting gannets departed and never returned after January 2018.
- ✓Island restoration timeline: Mana Island transitioned from over 100 years of sheep and cattle farming — which destroyed native vegetation and enabled invasive mouse populations that decimated bird and lizard eggs — to a functioning conservation refuge after New Zealand's Department of Conservation removed all invasive species in the 1980s and began active replanting programs.
- ✓Social monogamy in gannets: Gannets are socially monogamous and typically mate for life, using elaborate courtship rituals including synchronized neck-stretching, wing-raising, and beak-clacking to reinforce pair bonds. This behavioral hardwiring explains why Nigel directed full courtship displays, nest-building, and sustained proximity toward a single decoy rather than distributing attention across multiple statues.
What It Covers
Radiolab's 25-minute episode chronicles Nigel, a male gannet who landed on New Zealand's Mana Island around 2016, becoming the first real bird drawn to a two-decade-old decoy colony project, then spent years courting a concrete statue before dying alone in January 2018.

Notable Moment
When three live gannets finally arrived on Mana Island after years of waiting, Nigel — the bird everyone expected to lead the new colony — showed zero interest in them. The newcomers equally ignored Nigel, positioning themselves on the opposite side of the colony entirely.

I'm Latif Nasser. And today, we have a small story about a small life that touched people all over the world. Okay. One, two, three. And it doesn't end the way you want it to. God, there's a door. We'll get enough. You'll be fine enough. Comes to us from producer Annie McEwen. Hi, Annie. And it starts with a total loner. Yeah. Exactly. I'm okay. Let's picture you. I imagine that you're tall and you stride around the island in like hiking boots? Like, oh gosh, yes, tall. So tall, I've got quite bad posture and sort of loom around the Oh, so you're hunching around the island? Hunching and stalking. Yes. Scowling, but under a sun hat because the the sun's pretty strong in New Zealand. This is Chris Bell. And back about a decade ago, he was the sole inhabitant of an island off the West Coast Of New Zealand called Mana Island. Oh, gosh. It's like the perfect size of island. It's not too big and not too small. Nose to tail, it takes about an hour and a half to walk across. Yeah. Looking down. Yeah. Of course. It's got cliffs, a high grassy plateau, shrubs, and woodland. And Chris lived there in an old farmhouse. Yeah. A wood stove and and Did you make your own food all the time? Well, there's no one else to make it for me. So yeah. Although he did share the house with Handfuls of geckos. A whole bunch of geckos. As soon as evening came, you would hear them rattling about in the roof space. And sometimes he'd get human visitors, but Very common to go ten days without seeing or hearing anybody else. Often, he'd be totally alone. Yeah. Okay. And what is how how did he why why is he is he spurning civilization? What is he doing there? Well, this island was sort of in a state of recovery. Gosh. It was farmed for many years. For a hundred plus years, it had been used as farmland. I think it was sheep and cattle. And in all this time, the wildlife took a big hit. The sheep and the cows ate all the grass and …
