Physical description Click here for a physical description Tawny Grassbirds are among the largest reed birds in Australia. Their plumage is cryptic. Their front, from throat to undertail coverts, is creamy, the cap is reddish-brown with some darker streaking. The back is brown, with prominent dark-grey streaking, mostly on the wings. The flanks and sides have a buff wash. The brown tail is conspicuously long. The eyes have dark-brown irises. The relatively long, almost straight bill has a grey upper mandible, the lower mandible is horn-coloured. The legs and feet are grey. Twitcher's tip Compared with other reed birds, Tawny Grassbirds are the tallest that have striation in their plumage.

Range, habitat, finding this species Click here for information on habitat and range The overall distribution of this species can be assessed, and specific locations where birds have been spotted can be found, based on individual sighting reports submitted by birdwatchers to ebird.org . The global distribution of the Tawny Grassbird is available HERE . The range of the Tawny Grassbird exentds from the Philippines in the North, via eastern Indonesia, Timor Leste and New Guinea to Australia. In Australia there is one race of Tawny Grassbirds, "alisteri", which is endemic. They are found along the North and East coast of Australia, including the Top End of the NT to about Katherine, ranging from about Broome, WA, in the West to Sydney, NSW, in the South-East, and also in the near-coastal ranges, up to a few hundred km inland. They are not found much farther inland than the western slopes of the Great Dividing Range. Tawny Grassbirds live in swamps or reeds, e.g. in estuaries of rivers.

Sightings Click here for sighting information Race "alisteri" A Tawny Grassbird, race "alisteri", was first spotted by us at Old Bar, NSW, in the estuary of the Manning River, in September 2011. Since then we have consistently found them on, and they have been reported by various contributors from, the (near-)coastal fringe of NSW and QLD, in particular in the area from Old Bar, NSW, to the Sunshine Coast, QLD. Subsequently they have also been found by us in other locations along the NSW coast, e.g. MacPherson Road swamp in Tuggerah, NSW. C. Hayne reports that Tawny Grassbirds, race "alisteri", are occasionally seen in various locations near Moree, NSW, mostly to the West and North-West of town, but in December 2012 also in the township. Since 2012 they have become quite common in the Gwydir Wetlands, where a single bird was spotted and photographed in June 2013. At Narrabri Lake a Tawny Grassbird, race "alisteri", was first spotted by us in August 2013. M. Mearns reports spotting Tawny Grassbirds, race "alisteri", on Lady Elliot Island, near Agnes Water, QLD, in January 2016. M. Windeyer reports spotting a Tawny Grassbird, race "alisteri", at Frog Hollow, Gilgandra, NSW, in January 2017. M. Eaton reports spotting Tawny Grassbirds, race "alisteri", occasionally in south-eastern QLD, near both fresh water and saline water. B. Hensen reports finding Tawny Grassbirds, race "alisteri", occasionally at Eastlakes Golf Course, Sydney, NSW. P. Brown reports spotting Tawny Grassbirds, race "alisteri", along Channel Island Road, Darwin, NT, in July 2018. From August/September 2021 on, well into 2022, we found Tawny Grassbirds, race "alisteri", in the Upper Bullawa Creek section of Mt. Kaputar NP, near Narrabri, NSW. J. Boettcher, FNQ Nature Tours reports finding a Tawny Grassbird, race "alisteri", along Boar Pocket Road, Tinaroo, QLD, in January 2019, and at Hasties Swamp, Atherton, QLD, in November 2020.
