The huayco tinamou (Rhynchotus maculicollis), also known as waypu (Quechua)[3][4] (also spelled guaipo, huaipo, guaypo, waypo, a name which is also applied for other Tinamidae species[3]), is a species of bird found on grassy mountain ridges in the Andes of Bolivia and Argentina.

[6] Previously, it was considered a subspecies of the red-winged tinamou, but it has a different song, and its head and neck are streaked and spotted black.

They also eat small amounts of invertebrates, flower buds, tender leaves, seeds, and roots.

The nest is located on the ground in dense brush or between raised root buttresses.

[6] The huayco tinamou lives in the Andes of northwestern Argentina and Bolivia from 1,000 to 3,000 m (3,300–9,800 ft).
