Dave Bonta's short poem begins in a calm, almost meditative routine. The speaker is counting warblers, reciting their names (hooded, worm-eating, cerulean, black-throated green) the way someone might move through a set of prayer beads. The naming is soothing, a small ritual that brings order and attention to the morning.
Then the mood shifts. A black snake rises up "like an instant tree," a striking image that makes the creature seem to appear out of nowhere, as sudden and strange as a tree growing in a second. That jolt sends the speaker's mind to something darker: "the deadly false Edens," the "acres of glass." The glass most likely suggests windows and buildings that birds mistake for open sky and fly into. The speaker seems to feel a quiet grief, and perhaps some guilt, that the world looks welcoming to birds while hiding real danger. The poem moves from peaceful devotion to unease, and it leaves that feeling unresolved.
