A water bird, alternatively waterbird or aquatic bird, is a bird that lives on or around water. In some definitions, the term water bird is especially applied to birds in freshwater ecosystems , although others make no distinction from seabirds that inhabit marine environments .
Aequornithes (/ iː k w ɔːr ˈ n ɪ θ iː z /, from Latin aequor, expanse of water + Greek ornithes, birds), or core water birds, [6] are defined in the PhyloCode as "the least inclusive crown clade containing Pelecanus onocrotalus and Gavia immer".

The long period of evolution and shifts from one kind of waterbird lifestyle to another have obscured many plesiomorphies, while apparent apomorphies are quite often the result of parallel evolution, for example the "non-diving duck" type displayed by such unrelated genera as Dendrocygna, Amazonetta, and Cairina. For the fossil record, see below.
This is because almost all orders of aquatic birds living today either originated or underwent a major radiation during that time, making it hard to decide whether some waterbird-like bone belongs into this family or is the product of parallel evolution in a different lineage due to adaptive pressures.
