"Broken broken broken" lands like three hammer blows, with no commas to soften them. Dave Bonta's "Migratory" begins in the middle of a loss, and the poem never fully explains what has been lost. The speaker's "high gray room" might be a house, a sky, or a sense of safety. Then comes the stranger image of "my hill on wet stilts," a hill that seems to have lost its solid ground and now balances on thin, damp supports. Even the speaker's landscape has become unstable.
The questions that follow ("How did it happen?" "Who made off with / the sudden searing roots?") treat the loss as a theft, as though someone had slipped in and taken what held everything down. The phrase "sudden searing roots" is the poem's most startling pairing. Roots are slow, hidden and quiet, while "searing" is the language of burns and sudden pain. The line suggests that being pulled up from a place hurts the way fire does, and that you only discover how deep your roots went when they are torn out. The next couplet turns this into a bitter paradox: "They were showing us / how it feels to belong." The pronoun "they" has no clear antecedent. The nearest plural is "roots," which would mean that belonging is taught through its removal, but the line leaves room for other readers to hear the birds, or even the intruders, behind it.
The poem then pivots from the speaker's grief to a hermit thrush, "at the end of summer," whose bog "occupies the spot" where, 8000 years ago, "a castle of ice dissolved / into a watery keep." The metaphor is a clever one. A glacier becomes a fortress, and its melting becomes a siege ending quietly, with the keep, the castle's innermost stronghold, filled by water. Judging by the imagery, the poem has in mind a bog formed by retreating ice. The scale shifts abruptly from one person's broken room to eight thousand years, and that shift reframes the opening. Compared with the bog's long history, the speaker's loss is brief, yet the poem doesn't make it feel small. It places it inside a landscape that has always been unmade and remade.
The military vocabulary continues with "Latter-day invaders," who "have left / their jagged ladders / for the woodpeckers." The poem does not say who they are, but "latter-day" sets them against the ice's ancient arrival and suggests people. The "ladders" are open to interpretation. They might be stumps, cut trunks, or scarred trees, but whatever they are, the woodpeckers take them over. Nature makes use of the damage without forgiving it. The final image is the most haunting: "perfectly preserved / in the tannic waters, / their empty nets." The word "tannic" suggests the dark, tea-coloured water of a bog, and the poem implies that such water holds things intact. What it preserves are nets with nothing in them. Whatever the invaders hoped to catch, they did not, and the evidence remains in plain view.
Formally, the poem is free verse with no rhyme and almost no end punctuation. It does have a quiet architecture. The first four stanzas are couplets, short and clipped, and they hold the questions and the shock. The last four are tercets, and the sentence stretches across them, running through "where," "into," and "&" without stopping. The ampersand gives the final stanzas a casual, jotted feel, as if the speaker is looking and writing at once. The sound of the language also does work. The hard, stuttering "b" and "k" of "Broken" and "bog" and "keep" give way to the long, dissolving vowels of "watery" and "tannic."
The poem's significance lies in how it makes personal displacement and ecological history comment on each other. Its title, "Migratory," points to the thrush, a creature that is at home precisely because it leaves and returns. The poem asks whether belonging can survive when the return is cut off, and it answers with an image, not a statement: a bog full of empty nets.
