The Australian reed warbler (Acrocephalus australis) is an acrocephalid warbler in the genus Acrocephalus and is the only Acrocephalus species native to Australia.

The species name australis is translated to mean "southern" in Latin, and refers to the species range, Australia. In its western range the Australian reed warbler is also known as "Koordjikotji" (pronounced core'chee'caw'chee) in the local Aboriginal language of Perth and its surrounds.
Formerly placed in the then "wastebasket" family Sylviidae, the genus Acrocephalus is now included in the family Acrocephalidae, which encompasses 60 species in 7 genera widespread across Africa, Europe, Asia and the western Pacific regions. Within the Acrocephalidae, the Australian reed warbler is recognised as belonging to a monophyletic group consisting of Palearctic and Australasian region species. However, recent mitochondrial DNA analysis infers that pacific Acrocephalus warblers can be divided into two... Wikipedia →

Possible
About 20% of wildlife watchers report an Australian Reed Warbler sighting in Perth on a given day, based on 1,710 verified sightings from GBIF citizen-science data. It is the 44th most-seen of the 162 birds we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
January and April
In those months about 30% of wildlife watchers report an Australian Reed Warbler in Perth on a given day, against about 10% in March and June, the lowest months. Those are among Perth's driest months, with about 25 mm of rain a month against 130 mm in July.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Australian Reed Warbler sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 4 cities where we can rate Australian Reed Warbler sightings, Perth has the highest daily chance: about 20%. Next come Brisbane (Australia, about 20%) and Melbourne (Australia, about 10%).
Same order: Passeriformes
The closest relatives of the Australian Reed Warbler that you can see in Perth (order Passeriformes, Perching Birds) are Australian Raven (about 90%), Willie Wagtail (about 90%) and Red Wattlebird (about 90%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Australian Reed Warbler is recorded against all the birds logged in Perth (1,710 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
