Physical description Click here for a physical description Weebills are very small bushland birds. They are amongst the smallest birds in Australia. Their plumage has inconspicuous colours ranging from yellowish-grey (front) to olive-brownish-grey (back) to a grey tail with white terminal band. The throat is greyish, sometimes with some striation. Weebills have a light eyebrow compared to the surrounding facial colours. The top of the upper mandible of the short bill is grey, whereas the rest of the bill is horn-coloured. The eyes have greyish irises. The legs and feet are grey. Details of the colour pattern depend on race. Race "flavescens" is the yellowest, "occidentalis" is greyer than the others and "ochrogaster" is paler than the rest. Juveniles have a brighter, yellowish bill.

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 Weebill is available HERE . Weebills are endemic to Australia. In total there are four races of Weebills that populate almost the entire Australian continent, with the exception of the Lake Eyre Basin, most of the great sandy deserts of WA and the Nullarbor. Nominate race "brevirostris" populates eastern and central QLD and NSW and all of VIC. Race "flavescens" is found in western QLD and the Cape York peninsula, plust the entire NT and the Kimberley in WA. Race "occidentalis" lives in an area including the western-most edge of NSW (West of Broken Hill), southern SA and south-eastern WA (along the West coast up to about Dirk Hartog Island. Race "ochrogaster" is found in the northern half of western WA, up to the catchment of the Fitzroy River, and along a narrow stretch from central WA towards the NT/SA border. Weebills are usually found in forest, including dry (often sclerophyll) forest, and open woodland. They normally stay high up in the tree crowns.

Sightings Click here for sighting information Race "brevirostris" Weebills, race "brevirostris", are found by us regularly in northern inland NSW. They were spotted by us e.g. 20 km South of Narrabri, NSW, at Deriah Aboriginal Area, 30 km East of Narrabri and also 20 km West of Barraba, NSW.

We also spotted Weebills, race "brevirostris", including fledgling birds, at Bullawa Creek SCA, 15 km East of Narrabri, in June 2008 and August 2011. C. Hayne reports that Weebills, race "brevirostris", are also common in the area of Moree, NSW. R. Plumtree reports spotting Weebills, race "brevirostris", in Ensay, East Gippsland, VIC, in January 2018. This location is near the southern boundary of the species' range. We find Weebills, race "brevirostris", regularly in remnant woodland between Pilliga and Burren Junction, NSW. M. Eaton reports finding a Weebill, race "brevirostris", at the Bowra Wildlife Sanctuary, which is near the western boundary of their range, on various occasions. They were also found at the Roma Bush Gardens, Roma, QLD, in August 2022. Race "occidentalis" Weebills, race "occidentalis", were spotted by us at Arkaroola, in the Gammon Ranges, SA, in March 2008. J. Greaves reports spotting Weebills, race "occidentalis", at Koondoola Reserve, Perth, WA, in July 2016. R. Plumtree reports spotting Weebills, race "occidentalis", between Berri and Renmark, SA, in September 2018.
