A mysterious sound echoes through the forest, sparking the curiosity of three birds: an owl, a jabiru, and a parrot. As they try to uncover its source, each imagines a different explanation, transforming a simple noise into a playful exercise in observation, imagination, and suspense. But when the mystery is finally solved, an unexpected surprise awaits.

Written by Telma Guimarães, one of FTD Educação’s most widely translated authors, in partnership with Jonas Ribeiro, the story builds anticipation through repetition, rhythmic language, and a sequence of increasingly imaginative hypotheses, making it especially effective for reading aloud and shared reading experiences.

Esteban Vivaldi’s vibrant illustrations enrich the narrative with expressive characters, dynamic perspectives, and visual representations of the birds’ imaginations. The interaction between text and image invites readers to participate in the investigation, while subtle metafictional elements culminate in a celebration of books and storytelling itself.
