In just a few lines, this poem catches a small moment of life starting up in a cold place. The woods are chilly, yet they "sing" all morning, and the poem soon tells us why: a wren is building a home by the water. The bird's song fills the whole landscape, and the cold seems to lose some of its grip.
The speaker doesn't say much about their own feelings, but the attention is itself a kind of feeling. They are listening closely and clearly delighted. Calling the wren "bold" suggests admiration for how loud and confident such a small bird can be. Building a home there, in cold woods, feels like a quiet act of hope.
The mood is fresh, gentle and cheerful. The short lines and the pause between the two stanzas let the song ring out first, then reveal its source, almost like looking up and spotting the bird.
