Vestigiality describes homologous characters of organisms that have seemingly lost all or most of their original function in a species through evolution.
A penguin uses its wings to 'fly' underwater, the animal being aqua-dynamic; an eagle uses its wings to fly in air, the animal being aerodynamic.
Neither sets of wings are vestigial structures.
A penguin's vestigial structure is its wings. Penguins have evolved to be flightless, so their wings are no longer used for flying. Instead, they have adapted to use their wings for swimming in the water.

vestigial structures
Unused structures are classed as vestigial structures. One example is the wings of a penguin or , ostrich, who are flightless birds. Another example is the sightless eyes of creatures that dwell in deep dark caves - where they wouldn't be able to see at all.
Vestigial wings.
The penguin uses its beak to catch fish. It also uses its vestigial wings as flippers, making it a very fast and agile swimmer.
They have feathers they have beaks they have wings they do poo and wee

A vestigial structure is a physical characteristic of an organism that has lost its original function through the process of evolution. These structures are remnants of traits that were once useful to the organism's ancestors but are no longer needed in their present form. Examples include the human appendix and the wings of flightless birds.
The vestigal feature of a kiwi is it's wings.
