Great frigatebird (Cốc biển đen, Fregata minor) 

The great frigatebird (Fregata minor) is a large seabird in the frigatebird family.
The great frigatebird has a wide distribution throughout the world's tropical seas.
This species is migratory.

The term Suliformes is a taxonomic order of birds—including gannets, boobies, and cormorants. It is derived from a combination of the Latin word sula (gannet) and the Latin suffix -formes (having the form of).

Fregatidae is the scientific family name for frigatebirds. It is derived from New Latin, combining the genus name Fregata (from the French frégate, a type of warship) with the standard zoological suffix -idae. In Greek, they are often referred to as Φρεγάτα (Fregáta).

Like the genus name, the English term is derived from the French mariners' name for the bird la frégate—a frigate or fast warship.

The word "minor" originates from Latin with the primary meaning of "lesser," "smaller," "junior," or "inferior".
