Stanza-wise Explanation

Stanza 1 — The silent tree

"The Laburnum top is silent, quite still / In the afternoon yellow September sunlight, / A few leaves yellowing, all its seeds fallen."

The poem begins in absolute stillness. The top of the laburnum tree stands silent and motionless in the soft yellow sunlight of a September afternoon. A few of its leaves are already turning yellow and all its seeds have fallen. The mood is quiet and almost lifeless — the tree seems tired and empty as its season draws towards a close.

Stanza 2 — The goldfinch brings the tree to life

"Till the goldfinch comes, with a twitching chirrup ... The whole tree trembles and thrills."

The stillness lasts only until a goldfinch flies in with a quick, twitching chirp — a sudden, startling burst of movement at the end of a branch. Sleek, alert and abrupt as a lizard, she darts into the thick leaves, and instantly the tree springs to life: "a machine starts up" of chirpings, a tremor of wings and trilling sounds. The whole tree seems to tremble and thrill with energy. The image of a machine suggests the sudden mechanical rush of noise and vibration the bird's arrival sets off.

Stanza 3 — The goldfinch departs and stillness returns

"It is the engine of her family ... And the laburnum subsides to empty." …
