[2] It has a similar pattern of coloration to the smaller Carpentarian grasswren (A. dorytheae), which occurs on sandstones hundreds of kilometers to the east of the Arnhem Plateau.

White-throated grasswrens have soft, high-pitched contact calls that sound very similar to the co-occurring purple-backed (lavender-flanked) fairywren (Malurus assimilis dulcis), but also produce a complex song of trills and warbles.

[5] Local knowledge by Bininj Nawarddeken people has identified sightings of the white-throated grasswren near outstations in the Warddeken Indigenous Protected Area, including Manmoyi, Kamarrkawarn, and Kabulwarnmyo in place where ‘karri kore kanjdjikandji, ankebkakebkali’, translating to ‘the river by the edge of the rocks where they meet the savanna’.

[6] It is therefore threatened by more frequent bushfires (over 50 in 2021, with climate change playing a role in the increase[7]), leading to inadequate habitat quality and lack of reproductive success.

[1] As of 2022[update] it has disappeared from many of the locations where it used to be spotted frequently, such as near Gunlom Falls in Kakadu National Park, Plum Tree Creek, the large population near the East Alligator River.

[8] As of 2022[update] Wardekken Indigenous rangers have been working on a project to help conserve the species with non-profit organisation Territory Natural Resource Management, funded by the federal government.
