"There are two nights a hollow nester is most likely to die." Why a 72-year-old craftsman from the Dandenong Ranges is releasing his final hand-carved nest boxes far under gallery price, before his hands give out for good.

300 million birds, and nowhere left to nest
Since 1990, Australia has lost an estimated 300 million birds. More than 1 in 5 of the country's native bird species is now listed as threatened or near-threatened, according to BirdLife Australia's 2024 State of Australia's Birds report.
"Woodland birds have declined by more than 50% in parts of south-eastern Australia over the past three decades, driven largely by the loss of old-growth trees with natural hollows."
BirdLife Australia, State of Australia's Birds (2024)The causes are many: land clearing, feral cats, foxes, and habitat loss. But for Australia's hollow nesters — the rosellas, treecreepers, pardalotes, and small owls — part of it is heartbreakingly simple. The old eucalypts and dead timber they raise their young in keep getting removed, and a bird that cannot dig its own hole has nowhere left to go.
These are the birds that keep a garden alive. Native birds control insects through every season, and a pair of superb blue wrens feeding a clutch will catch thousands of invertebrates before the chicks can fly. Lose the nesters, and the garden is left to the pests.
Woodland and garden birds like the Superb Fairy-wren have been among the hardest hit.
"There are two nights a hollow nester is most likely to die."
The first is a cold winter night. A small pardalote or wren can lose a dangerous fraction of its body weight before morning just maintaining its warmth, and the ones that survive until dawn are the ones that found a hollow to shelter in.
The second comes in spring, after the eggs. A nest is only as safe as its entrance. Cut it too wide, and an Indian myna or a currawong can push in and take the whole brood.
The answer turns out to be an old one: a nest box carved as a face. Thick solid walls that hold more of a sleeping bird's warmth than a thin ply box will, and a mouth cut small — room for a pardalote and too narrow for a myna. The man who makes them has spent his life learning how.
The man who has spent his life answering it
In a shed outside Emerald, Victoria, a 72-year-old named Amos Hensley has carved these nest boxes by hand for 44 years. More than 3,000 of them, each from a single block of wood, no glue, no seams. His neighbours call the faces watchers, set at the edge of a garden to look over it.
Amos Hensley at his shed outside Emerald. The wood dries two full years before he touches it.
He did not learn what a bird needs from a book. He learned it watching which broods lived inside his work and which did not. Ask him why a pardalote picks one box over another, and he will not talk about how it looks. He will talk about how it is built.
"I'd rather a wren live in it than a collector hang it on a wall."
Why birds move into an Amos Hensley watcher
It comes down to a handful of things a factory never bothers with, and the strange part is that the very features that make the face a face are the ones that keep a brood alive.
What sets a Hensley watcher apart
- The Single-Block Build. Carved from one solid piece of timber. No glued seam to swell, crack and let go in a wet season, the way plywood boxes do, usually with a nest still inside.
- The Small Bird Mouth. The open mouth is cut to roughly 28 mm: right for pardalotes, wrens and treecreepers, too small for mynas, currawongs and the predators that raid a nest.
- The Hooded Rain-Brow. The deep-carved hood overhangs the entrance like an awning. Rain sheds down the face and off the chin, so it never runs into the nest.
- The Hidden Drain-Vent. That second small hole below the beard isn't decoration. It drains any water that gets in and lets hot air escape on a January afternoon.
- The Solid-Wood Thermal Mass. Thick solid walls hold the nest's warmth through a cold snap and stay cool in high summer. Amos calls it "a thermos for eggs."
- The Living Patina. Left untreated, the wood silvers over the years and becomes part of the garden, instead of peeling and flaking like a painted box.
One block, start to finish, by one pair of hands
His workshop is a converted old shed, lit by one north-facing window and a lamp over the bench. The timber dries in the corner for two full years before he touches it, which is part of why it holds together outdoors. Each face takes him the better part of a dozen hours.
He does not sketch first. "I don't decide the face," he says, turning a block under the lamp. "The grain tells me where the nose goes."
Hang one outside and leave it be. Come spring, a wren may be looking back at you out of its mouth.
A wren at the mouth, come spring.
The face comes back every spring. Amos may not.
Two winters ago the arthritis reached the base of his right thumb, the exact joint that drives the knife. He can still rough out a block. What he can no longer do is the fine work, the small cuts around the eye that turn a lump of wood into a face that looks back at you. His doctor told him plainly that it does not come back.
There are 61 finished nest boxes left on the drying shelf. When these are gone, there will not be more.
"The birds are running out of places to nest, and I'm running out of time to make them," he says. "I'd like to get the last of these into gardens while I still can. That's where I could use the help."
The small cuts around each eye. That is the part his thumb can no longer hold.
Priced for a garden, not a gallery
The galleries in Melbourne would take every one of these at a high price and hang them on a wall, where no bird would ever use them. Amos would rather they go outside. So these go out far under gallery price, on the hope that come spring a bird raises a brood in the mouth of one.
Where Amos hopes every one of them ends up: outside, in a garden.
"44 years of faces, and I'm down to the last of them."

The people who took one home
"It arrived solid and heavy, hung on the gum tree in April, and by September we had a pair of wrens nesting inside. My kids named it Grandpa Gum."
Danielle R., Emerald, VIC
"I'd bought three nest boxes from Bunnings and every one fell apart in a season. This is a different thing entirely. You can see the tool marks, and it has held up beautifully through a wet winter."
Thomas B., Ballarat, VIC
"I gave one to my father for his 80th and he teared up. A real person made it, and it will outlast every cheap one I've owned. I ordered a second for our own garden."
Karen M., Bowral, NSW
Good to know
The questions people ask first
Is it garden art or a real nest box?
Both. The face is the art. The small mouth, the hooded brow and the drained floor are what make it a working home a wren or pardalote will actually nest in.
Where should I hang it?
From a sturdy hook, a post, or a branch a few feet out from the trunk, roughly 1.5 to 3 metres up and near cover — somewhere a cat or possum can't jump straight to it. No hanging box is fully predator-proof, so keep it clear of easy launching spots.
How do I keep it going?
Give it a wipe of boiled linseed oil once a year, after the brood has fledged, and it will weather season after season, greying to a soft silver. Clear out the old nest at the same time.
Where can I get one?
Only here, on this page. Amos's nest boxes are not sold on eBay, in stores, or through any marketplace. His granddaughter set up this one page for him.
Can I try one with no risk?
Yes. Every one comes with a 30-day guarantee. If the piece isn't what you hoped when it arrives, email us and send it back. No questions, no hassle.
