Uncle Marcos from the house of the spirits

From the text:

When the crates were opened, they were found to contain loose bits of wood, metal, and painted cloth. Marcos spent two weeks assembling the contents according to an instruction manual written in English, which he was able to decipher thanks to his invincible imagination and a small dictionary. When the job was finished, it turned out to be a bird of prehistoric dimensions, with the face of a furious eagle, wings that moved, and a propeller on its back. It caused an uproar.
