Australasian Reed-warbler (Acrocephalus australis)


French: Rousserolle d’Australie German: Australrohrsänger Spanish: Carricero australiano
Other common names: Australian Reed-warbler

Calamoherpe australis


, 1838,

Parramatta, New South Wales, Australia


Has been considered a race of A. stentoreus, but molecular analysis supports treatment as separate species; populations from Indonesia to Solomons, previously placed in A. stentoreus, united with present species based on morphological and vocal evidence#R. Birds on Buru have occasionally been separated as race toxopei; race sumbae, proven to form part of present species genetically#R, has sometimes been subsumed into celebensis. Eight subspecies recognized.
