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

The name Procellariiformes comes from Latin, combining procella (meaning "storm" or "gale") with -formes (meaning "shape" or "form"), literally "storm-shaped" or "storm-like," fitting these seabirds' reliance on wind for flight, and refers to their stormy habitats and powerful wings. 

The name is derived from the type genus Procellaria which in turn is derived from the Latin word procella meaning "storm" or "gale".

The genus name comes from Ancient Greek kalos, "good" and nectris, "swimmer".
