Nineteen words are enough to turn one speaker into two animals, and the speed of the change is part of the point. "Shape shift" gives us no transformation scene, no fur sprouting or feathers unfolding. The speaker simply declares, "I am an owl," and a few lines later, "I am a bear." There is no "like" or "as if" to soften the claim. It is a flat metaphor, stated with total confidence, and the title tells us that this kind of change is easy and perhaps constant.
What interests the poem is what each animal brings with it, and Dave Bonta gives each one a parenthesis. The owl comes with "(who calls my name)," a phrase that can be read at least three ways. The owl may be a creature whose call is its own name, since "who" is close to the sound an owl makes. It may be an owl that calls the speaker's name, as though the identity arrives from outside, summoned by a voice in the dark. Or "who calls my name" may be a question with the question mark left off: who is calling me? The poem never chooses, and the ambiguity suits an owl, a bird we usually hear before we see. Its identity is made of sound and of being addressed.
The bear belongs to a different world. Where the owl is voice, the bear is appetite: "so much pursuing / of a tangier supper." The phrase is wonderfully odd. "Tangier" is a comparative, so the bear is never satisfied with the supper in front of it and is always chasing one that is sharper and more vivid. The word suggests a sour or biting flavor, something that makes the mouth pay attention. And "so much pursuing," with its vague, almost weary "so much," makes hunger sound less like a ravenous roar and more like a long, habitual labor. Anyone who has stood in front of an open fridge wanting something they cannot name will recognize the bear.
Set side by side, the two stanzas suggest a small theory of what a self is made of: being called and being fed, a name and a supper. The owl wants, or is given, recognition. The bear wants flavor. Shifting shape here means shifting which of these basic needs is speaking.
The poem's construction supports this. It has no rhyme and no punctuation apart from the parentheses, and the only capital letter is the "I," repeated twice like a fixed point while everything around it changes. The first stanza is tidy: "I am an owl" and "(who calls my name)" each run to four syllables, a small balanced pair. The second stanza begins the same way with "I am a bear," then loosens. The lines lengthen as they go, and the parenthesis, which closed neatly within a single line for the owl, now spills across a line break. The form acts out the difference between the two animals. The owl is compact, and the bear's hunger runs on past where it should stop.
The sounds work quietly too. "Owl," "calls" and "name" share a rounded, hollow quality, the open vowels of a call across distance. The bear's lines are busier, with the repeated s and p of "so," "pursuing" and "supper" and the clipped "tang" in "tangier," which adds a taste to the line. Even the title is built from sound: "shape" and "shift" both begin with that soft hush of "sh," as if the words were already sliding into one another.
The parentheses matter most of all. They make each animal's defining quality sound like an aside, something the speaker mutters from inside the shape, a private note that slips out. The declaration "I am a bear" is public and certain, while the parenthesis admits what being a bear actually feels like. Because the poem never closes with a full stop, the sequence feels unfinished, as though a third animal could follow.
That openness is what makes the poem worth reading. It treats identity as something we try on, one creature at a time, through what we hear and what we crave, and it does so in a handful of words that leave the reader to decide which animal they are today.
