Vestigial wings.

the kiwi
A kiwi, like all birds, does not have a backbone. Instead, it has a lightweight, flexible structure called a keel that provides support for its flight muscles. The keel is a modified sternum (breastbone) that allows for the powerful wing movements necessary for flight. Additionally, kiwis have a unique feature among birds: they have vestigial (non-functional) wings, as they are flightless birds.
It must be homologous to some feature in an ancestor.
