Think back over the garden days. A rabbit nailed against the sky, ears snapping in the wind, makes the coldest promise of his life: never again. Below him a hired boy hoes rows and talks upward, softly, the way the lonely do. Then a moonlit climb, a run through the dark, a bare cabin — and thin arms closing around him like an answer. The heart he canceled comes back without asking permission.

For as long as people have farmed, birds have arrived at harvest time — and farmers have posted guards that never sleep. The scarecrow is an ancient answer to an ancient pest: a person-shaped figure of poles, straw, and cast-off clothes, raised above the ripening rows. Egyptian farmers guarded grain beside the Nile; Japanese farmers still raise straw kakashi over rice paddies. The design is a bluff — from a bird’s-eye view, anything person-shaped that stirs in the wind might be a farmer, and might mean danger. The bluff’s weakness is its audience. Crows, the scarecrow’s oldest opponents, are among the cleverest birds alive: they study what never moves, test it from a safe branch, and within days may perch on the guard itself. So farmers learned that an effective scarecrow must change — new rags, a new post, a head that swings — staying one surprise ahead of its audience. A guardian of cloth and straw, it turns out, keeps its job exactly as long as it keeps its mystery.
