The vestigal feature of a kiwi is it's wings.
Vestigial wings.
Arguably, the strangest feature of a kiwi is its long beak. It is unique as the bird's nostrils are right on the tip of the beak, a characteristic which only the kiwi has. This gives the kiwi an excellent sense of smell, which is invaluable in helping the kiwi find food.

A vestigial structure is an anatomical feature that has lost most or all of its original function through evolution. An example of something that is not a vestigial structure would be the wings of birds, which are fully functional and essential for flight. In contrast, vestigial structures, like the human appendix, serve little to no purpose in the current species.
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.
Vestigial StructureA vestigial structure is a structure that appears to no longer have a use in the body.

The opposite of vestigial organs would be functionalorgans.
No, the claws of a lion are not vestigial.
All birds that exist today have wings, even the Kiwi whose wings are very rudimentary. However, there are many types of flightless birds that, as the name suggests, do have wings, but cannot fly.
Vestigial means a very small remnant of something once larger. The appendix is a vestigial organ. Some people are born with vestigial tails.
