The Manchurian bush warbler (Horornis canturians), also known as Korean bush warbler,[2] is a bird in the family Cettiidae.

The species was first described by Robert Swinhoe in 1860.

The estimated distribution size is reported to be a large range – approximately 1,610,000 km2.

Because of this, the Manchurian bush warbler is evaluated as a least concern species.

[4] It is often confused for the Japanese bush warbler.
