Australian Reed Warbler

Acrocephalus australis

The Australian reed warbler (Acrocephalus australis) is an Old World warbler in the genus Acrocephalus and is the only Acrocephalus species native to Australia.[2] It has also been observed in Papua New Guinea and nearby islands. This species appears long (15–18 cm), slender and plain, with drab brown plumage that varies with wear. Wing tips fall short of the uppertail-coverts giving the wings a short appearance. The beak is long and thin (17-23mm) with a slightly decurved bill that has a slight hook at the tip. The tarsus and feet appear long compared to the tibia which is short and feathered. Sexes are monomorphic. In fresh plumage, birds have russet brown plumage extending from the crown down to the back. The uppertail-coverts are rufous, the tail measurers between 51–71 mm, the underparts and belly plumage is a duller rufous brown than the back, and white plumage is found on the throat and chin. An indistinct pale brown supercilium extends from close to the bill to midway on the ear-coverts, the feathers on the crown are slightly elongated and they are often raised to form a crest during song. Juveniles are very similar to adults but have yellowish-brownish uppertail-coverts and underparts. Worn plumage on rump and uppertail-coverts is duller and the upperparts have a grey or olive tinge, the underparts become faded and appear to merge into the paler throat plumage and the supercilium fades to white.
