Geographic range
Found in China, Korea and Japan. According to Gloyd and Conant (1990), there is no evidence to support claims that this species occurs in the Ryukyu Islands. The type locality given is "Japan."[1]
Habitat
Occurs in a range of habitats, including swamps, marshes, meadows, open woodland, rocky hillsides and montane rock outcroppings.[2]
Feeding
They hunt for birds and small rodents. Often found in and around farmland due to the associated rodent populations.[2]
Gloyd and Conant (1990) recognized five subspecies: the four mentioned in the table above, plus A. b. ussuriensis, which is found in Russia. However, Toriba (1986) elevated this fifth form to a species: Gloydius ussuriensis.[1][2]
This species is similar the cottonmouths and copperheads (Agkistrodon sp.) of the Americas and was long considered part of the same group (see synonymy).[1]
