What type of thing is a bird?
A bird can be described as all of the following:
Life form – entity or being that is living or alive.
Animal – multicellular, eukaryotic organisms of the kingdom Animalia (also called Metazoa). Their body plan eventually becomes fixed as they develop, although some undergo a process of metamorphosis later on in their lives. Most animals are motile, meaning they can move spontaneously and independently.
