Few poems begin with a confession as disarming as this one. The speaker has just finished a chore on his day of rest, a job that involved clearing the eave of a half-screened porch, and only afterward discovers what he has destroyed: a flycatcher's nest holding "five clear eggs." The first stanza ends not with reflection but with a bare exclamation, "Oh!", the sound of a person realizing too late. What follows is a small story of attempted repair, and its quiet refusal to give the speaker, or the reader, any comfort.
The central idea is that good intentions, and even careful afterthoughts, cannot undo harm done through inattention. The speaker does everything that seems reasonable. He leaves the porch door "wide open," leaves the nest and "the threatened eggs alone," and then goes away, placing his "perturbed hope" in "the flycatcher's instinct to claim her own." That phrase is worth pausing on. He is trusting nature to correct a mistake that he made, handing the bird a job he created. The word "perturbed" is honest about his motives: this is not serene faith but anxious wishing, a hope that the problem will resolve itself while he is out of the room.
The poem's structure mirrors this retreat. It is built from five quatrains rhymed ABAB, and the rhymes are often deliberately slightly strained, as in "Oh!" with "know," or "current" with "weren't." The meter has the loose, speech-like gait of a story told aloud, lines of roughly four stresses that stretch and stumble rather than march. This irregularity suits the subject. A tidier, more musical poem would feel like it was making a pretty thing from an ugly event; this one keeps its voice plain and slightly uneasy.
The imagery is where the poem earns its force. In the fourth stanza the eggs are described as "white moon to their five ends," a startling image that makes each egg a small, complete world, and the phrase "starred in a brooch of nest hair and shell" turns the nest into jewelry, something intricate and cherished. But the sentence is built on negatives: the eggs "weren't / Starred" in that brooch. We understand the loss through the absence of beauty before we learn its cause. The enjambment between those lines, with "weren't" stranded at the line's end, makes the reader feel the floor drop away.
The cause arrives in the final stanza, and it is typically oblique. Instead of the poet describing the destruction directly, we get "a ragged tooth's fragment, rough-broken in two, / By the chipmunk's hole." The harsh consonants of "ragged" and "rough-broken" are the roughest sounds in the poem, set against the soft, lunar language that preceded them. The evidence is read like a detective's clue: the speaker infers what happened from a single fragment, and it "affirmed why" the bird behaved as she did. Notice that the chipmunk is never accused outright. The speaker is reading signs, and the poem lets us do the same.
The last two lines are the most haunting. The flycatcher "flew / Around and around the apple boughs," and the repeated "around" enacts circling, searching, grief that has nowhere to land. The poem ends on this image rather than on any lesson or apology. The speaker, who has been so busy explaining his own hopes and intentions, is finally reduced to watching.
What makes the poem significant is its moral honesty. It would have been easy to end with the speaker feeling better, or to blame the chipmunk and call it nature's way. Instead the poem quietly keeps the weight where it belongs: the nest was removed by human hands, and everything afterward is consequence. The apple boughs, the open door, and the moon-white eggs all remain in view, but they cannot be put back as they were. In twenty lines, the poem shows how small acts of carelessness ripple outward into lives we never intended to touch.
