A speaker watches three crows make their way along a branch, and the whole poem is the act of noticing them. The opening “one, two, three crows” sounds like someone counting quietly, with the rhythm of the numbers almost mimicking cautious steps. Then “walk a branch” keeps the action small and plain, as if the crows’ movement and the branch are all that exist in the moment.
The speaker’s feeling is not stated, but it comes through in the attention itself: there is calm, curiosity, and a faint playfulness in counting animals as they appear. The mood is hushed and a little amused, like watching something ordinary until it becomes strange and interesting. Because the language is so spare, readers are left to picture the black birds against the branch and to share the speaker’s simple pleasure in looking closely.
