Brown booby (Chim điên bụng trắng, Sula leucogaster)

The brown booby (Sula leucogaster) is a large seabird in the booby and gannet family Sulidae.
This species breeds on islands and coasts of the Atlantic, Indian and Pacific oceans.

The English name "booby" was possibly based on the Spanish slang term bobo, meaning "stupid", as these tame birds had a habit of landing on board sailing ships, where they were easily captured and eaten.

Suliformes, Sulidae, or Sula is derived from the Old Norse word sūla, which refers to a gannet or a pillar.

The specific leucogaster is from Ancient Greek leuko for "white" and gastēr for "belly".
