Recycled PETG — no trees harmed
20+ year outdoor life
Our Mission

We're saving birds
by not cutting their trees.

Every wooden birdhouse on the market is built from cedar, pine, or redwood — the exact same trees that cavity-nesting birds depend on in the wild. We do it differently.

Bottles, not branches

Every house starts as recycled PETG — discarded plastic bottles diverted from oceans and landfills, turned into shelter for the species we love.

Trees stay standing

One Fledge body = one less tree felled for backyard décor. The cavities birds need most stay where they belong: in the forest.

Built to last decades

PETG doesn't rot, warp, or fade. A single Fledge house outlives ten wooden ones — fewer replacements, less waste, more birds raised.

Every house gives back

A portion of every drop funds bird conservation — Audubon, American Bird Conservancy, Cornell Lab. Buy a house, plant a future.

Plastic that saves forests. Forests that save birds. That's the trade we want to make.

The Modular System

One body. Infinite stories.

Pick a body sized for the birds in your region. Snap on the species-specific entrance panel. When the season changes, swap the panel — same house, new resident.

01

Find your birds

Search your location with our eBird-powered tool. We'll tell you exactly which species are nesting nearby.

02

Pick a body

Three sizes (Small, Medium, Large) plus open-front shelves cover every cavity nester and ledge nester in North America.

03

Snap on a panel

Each species needs a precisely-sized entrance hole. Our panels are engineered to the millimeter — the right hole, the right bird.

04

Swap with the seasons

Bluebirds in spring. Chickadees in winter. Same body, swappable panels — your house evolves with the year.

Limited Drops

Small batches. Lasting impact.

Every drop is a limited run designed around a season, a species, or a cause. When it's gone, it's gone — and a portion of every sale goes back to conservation.
