A wren wipes his bill on a roof ridge, and for the first half of the poem the morning unfolds like a page from a field notebook. His mate is already brooding a second clutch, clouds are gathering, a catbird is in full voice, and a deer sneezes in the weeds. Then the vocabulary shifts. "In Figure 1 we can see / how the trend lines wander," says a voice that seems to have wandered in from a lecture hall, and the title, "Illustrative," suddenly makes sense. We are looking at a captioned example, and the example is a man in a landscape who has lost his appetite.
That is the poem's central idea. It is about the distance between watching the world and feeling at home in it, and about a mind that reaches for charts when feelings are hard to name. The speaker never says he is low. He says only that he is "hunting my lost appetite / on the z axis." The appetite could be for food, for company, for writing, or for life in general. The poem leaves the word open, and that restraint is part of its honesty.
The form supports this deadpan manner. The poem is twelve unrhymed couplets, all lowercase and without punctuation. With no full stops, the observations drift into one another, and the short lines give the pace of someone walking slowly and noticing. The line breaks do small, precise work. "The first clouds always" pauses on "always," so that it sounds like a weary rule of life, and only then does "look innocent enough" arrive. After "until they open," the next line delivers "their rainy mouths," a personification that turns weather into something faintly threatening. The repeated "first" is worth noticing too. The wren has moved on to a "second clutch," while the speaker is stuck among first signs of trouble. The bird's appetite for continuing contrasts quietly with his own lost one.
The most interesting move is how the poem lets technical language seep into nature before it fully announces itself. The catbird sings "instructions for assembly," a funny image if you know that catbirds are mimics whose songs sound like a jumble of borrowed phrases, a flat-pack manual read aloud. The speaker is already hearing the woods through the language of procedure. "This is how one gauges / one's aptitude for silence" then works as a hinge. It sounds like a test with a score, yet it follows a sneezing deer, a nice reminder that nobody, animal or human, manages silence perfectly.
After that, the graph and the landscape merge. "Trend lines" become "game trails converging / at the edge of a cliff." Both wander, both are made by repeated passage, and both end in a drop. "Game" also hints at hunting, which prepares the final image. At the bottom of the cliff "waves pound or traffic roars." That "or" is quietly devastating, because the speaker cannot tell, or does not care, whether the sound is sea or road. Natural and human noise have become interchangeable, and the poem has drifted a long way from the cheerful wren.
The ending is both comic and sad. "And over there it's me / with a stick" shows the speaker as a small figure in a diagram, seen from outside. The stick works as a walking stick, a hunter's weapon, and the pointer a lecturer uses to indicate a figure, so that one image holds all three. The final phrase, "on the z axis," suggests that the usual two dimensions cannot locate what he has lost. It must be somewhere in the depth of things. Judging by the imagery, the poem hints at real unease, but it never lets the feeling become melodramatic.
What makes the poem significant is this balance. It lets a joke and an ache share the same line, and it refuses to choose between the nature poem and the scientific paper. By borrowing the language of data to describe a walk in the woods, it shows how that language can keep feeling at arm's length, and how it fails to. The poem ends with no full stop and no resolution, just a person still looking.
