"Lotic" is a word from freshwater science. It describes moving water, like streams and rivers, as opposed to the stillness of ponds and lakes. Dave Bonta borrows that technical term for his title, then spends nine short lines showing that it can be made to splash. The poem gives us three kinds of creature at one stream: a wren in the air, a thrush in the water, and some people standing in the rain.
The first stanza is pure observation. A winter wren "darts low / over the rushing stream" and "unwinds its hurdy-gurdy song." The verbs do the work. "Darts" is quick and sharp, and the short, stressed words around it ("darts low," "rushing stream") move at the bird's speed. Then the last line stretches out. "Unwinds" suggests thread coming off a spool, so the song becomes something continuous, like the current below. A hurdy-gurdy is a stringed instrument played by turning a crank, and the word is as bouncy and slightly comic as the noise it names. Because the wren's song is famously long and tumbling, the comparison is affectionate as well as accurate.
The second stanza makes the poem's central claim, and it sounds almost like a naturalist's footnote: "Not all water-lovers / are buoyant in the same way." Buoyancy means floating, but it also means cheerfulness, and the poem plays on both. The wren is light enough to skim the surface. The waterthrush "walks / on the bottom," which sounds like the opposite of floating. Yet its "tail bobbing / as if spring-loaded" is the very picture of buoyant spirits. So the poem suggests that lightness need not mean rising above the water. A bird can be sunk to the stream bed and still be full of bounce. Loving water, on this reading, has many forms.
Notice how the structure supports this. The poem is three tercets in free verse, with no rhyme and no steady meter, so it reads like speech or like a watcher's quiet notes. But the sentences spill over the stanza breaks. "The waterthrush walks" ends one stanza, and "on the bottom" begins the next, so our eyes drop down the page just as the bird's feet find the stream floor. It is tempting to call that deliberate. Either way, the effect is that the lines flow into each other like water.
The imagery of machines is easy to miss. The song "unwinds," the instrument is a hurdy-gurdy, and the tail is "spring-loaded." All three belong to the world of cranks, coils and clockwork. Bonta describes living birds in the language of toys and mechanisms, which captures how wound-up and tireless they seem. It also makes the watchers look slower and softer by comparison.
That contrast arrives in the last two lines, where people appear for the first time: "We stand / dripping in the rain." The line break after "We stand" makes the speakers pause, rooted to the spot. The final word, "rain," also leaves us looking up and out, not at ourselves. The sound of "dripping" echoes the opening "darts," as if the poem were bending back toward its start. Nothing about the humans is graceful. They do not dart, float or bob. But because the poem has just said that water-lovers come in different kinds, the "we" can be read as one more kind: the kind that gets soaked and stays anyway. Being wet through becomes our way of belonging to the stream.
The poem is significant because it is so small and so unshowy. It pays attention to two specific birds, and it names them exactly instead of settling for "birds by a stream." It makes a real idea out of what it sees, and it does so with humor instead of solemnity. The compression recalls haiku: a few quick images, one turn of thought, and an ending that stops on a physical sensation instead of a moral. Its closing picture of people dripping beside a stream they cannot match is modest, but the modesty feels honest. The birds are at home in the water, and the watchers are only visiting. The poem finds that enough.
