Most poems about spring wait until it arrives. John B. Colwell's "Cardinal Calling to Spring" does something more interesting: it sets its scene in the last days of winter, when nothing has yet changed except one bird's confidence. The cardinal sits at the top of an elm, bright red against bare branches, and sings spring into being, or at least behaves as though that is what he is doing. The poem's central idea is that hope can be an act, not just a feeling. The cardinal is not reporting that spring has come; he is calling for it, and the poet, listening, learns to believe him.
The first stanza builds the bird out of one color. "Red is your head, and your wings, / And your crest; / Red like a rose / Is the red of your breast." The repetition does the work of a painter dabbing the same pigment across a canvas, and the rose comparison is a quiet surprise, since roses belong to summer and the cardinal is wearing them in winter. Then comes a sharper image: the bird is "aglow / Like a coal in a fire, / Burning with heat / Of an inward desire." The shift from plumage to fire turns the bird's color into warmth. He looks like heat, and the poem soon argues that he carries it too.
The second stanza turns to questions, and this is where the poem becomes thoughtful. What does the cardinal see from his perch? Can he "look into / The heart of a tree" and watch "its cold sap / Stir to new activity"? The poet imagines the bird as a kind of seer, able to perceive the invisible beginnings of spring: the first pulse in a bud, the coming of "nature's green flood." The word "somnolent" is well chosen, making spring sound like a sleeper who needs waking, and the cardinal's song is the alarm.
The third stanza gives the bird his defining quality: he is "confident, / Cheerful and bold." Against "March's bluster and cold" he has the "secret" of what is coming, and so "Icicles glitter, / 'Tis little you care!" There is humor in that line, a shrug in verse form. The poem also lets the bird do what "you love to do best," so that his call is joyful rather than dutiful.
Formally, the poem is built on short, bouncing lines, mostly two or three stresses each, which suit a small, quick-moving bird. The rhyme is steady and mostly simple: "spring" with "cling," "crest" with "breast," "fire" with "desire," "bold" with "cold." The sound pattern feels like the cardinal's own song, repeating and sure of itself. Even the opening "Cardinal, cardinal," returns at the start of the later sections like a refrain, so that the title phrase becomes a call the reader hears again and again.
The language is also worth noticing. Colwell mixes ordinary speech with old-fashioned forms such as "thou fearest," "canst thou," "cometh," and "I would fain join you." This slightly formal, almost hymn-like register lifts the bird above a mere backyard visitor and gives him something close to a prophet's dignity. Judging by these touches, the poem wants the cardinal's song to feel like a proclamation.
The final stanza completes the arc. After picturing spring's arrival (blossoms, bees, rain, "soft curtains of green"), the poet asks the bird to "let thy clarion ring," and the word "clarion" matters: a clarion is a trumpet, a call to action. The last lines state the poem's moral outright: "After the winter / Of chill and disease / Cometh, unfailing, / Green leaf, gentle breeze." Here winter is more than weather. By pairing it with "disease," the poem suggests hardship in general, and the cardinal's secret becomes the promise that hardship yields.
What makes the poem worth reading is its simplicity paired with that last turn. It would be easy to dismiss it as a light nature verse, but its real subject is faith in what cannot yet be seen. The speaker even admits envy, wishing he could join the song "Could I but sing." In the end, the poem asks us to be a little more like the bird: to sit in the cold, stay warm inside, and keep calling for the thaw.
