The Flag of the Azores (Portuguese: Bandeira dos Açores) is the regional flag of the Portuguese Republic. It is a rectangular bicolour with a field unevenly divided into blue on the hoist, and white on the fly. It is adopted in 1979 by the autonomous regional government of the Azores, and based on the traditional colours/symbols of the Portuguese flag, used until the Carnation Revolution.
Blue and white have always been the traditional colours used by the Portuguese nation.
The name of the archipelago comes from the Portuguese word açor, meaning goshawk, because it was supposed to be a common bird at the time of the discovery. However these birds never existed on the islands, they actually were a local subspecies of the buzzard (Buteo buteo), that was erroneously identified as goshawks by the first explorers. The bird on the flag is intended to be the celebration of that historical mistake. The Portuguese lesser arms are present in the top left corner of the flag.
