See text The hornero birds are members of the genus Furnarius in the family Furnariidae, native to South America.

[1][2] Horneros are brown birds with rather short tails and fairly long bills.

The size and exact shape of the hornero nest varies depending on the species.

They generally lay two to four eggs, although the breeding behavior of the bay hornero is virtually unknown.

All horneros are partially terrestrial, and commonly seen walking on the ground with a relatively upright posture.
