Calonectris is a genus of seabirds. The genus name comes from Ancient Greek kalos, "good" and nectris, "swimmer".

1/ Streaked shearwater (Hải âu mày trắng, Calonectris leucomelas)

The family Procellariidae is a group of seabirds that comprises the fulmarine petrels, the gadfly petrels, the diving petrels, the prions, and the shearwaters, in the bird order Procellariiformes (or tubenoses). The name is derived from the type genus Procellaria which in turn is derived from the Latin word procella meaning "storm" or "gale".

The mollymawks are a group of medium-sized albatrosses that form the genus Thalassarche, family Diomedeidae.
These were long considered to be in the same genus as the great albatrosses, Diomedea. The genus name combines the Ancient Greek thalassa meaning "sea" and arkhe meaning "power" or "command" (from arkho meaning to govern). The word mollymawk, dating to the late 17th century, comes from the Dutch mallemok, which means mal – foolish and mok – gull.

Albatrosses, of the biological family Diomedeidae, are large seabirds related to the procellariids, storm petrels, and diving petrels in the order Procellariiformes (the tubenoses).

Procellariiformes is an order of seabirds that comprises four families:
- the albatrosses,
- the petrels
- and shearwaters,
- and two families of storm petrels.

Formerly called Tubinares and still called tubenoses in English, procellariiforms are often referred to collectively as the petrels, a term that has been applied to all members of the order, or more commonly all the families except the albatrosses.

Ciconia nigra is from the Latin words for "stork" and "black" respectively.
