Physical description Click here for a physical description Yellow Thornbills are very small bushland birds. They are the smallest of all Australian thornbills. The front, from the throat down to the undertail coverts, is bright yellow, while the back is greyish olive-green with a brown tinge. The tail and flight feathers are brownish, with dark-grey edges. Yellow Thornbills have streaked ear coverts. The eyes have dark irises. The bill, legs and feet are black. Inland birds (race "modesta") have plainer colours than the coastal race "nana".

Taxonomy, classification See Yellow Thornbill at Wikipedia .

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 Yellow Thornbill is available HERE . Yellow Thornbills are endemic to Australia. The range of Yellow Thornbills is restricted to the East and South-east of the Australian continent. Nominate race "nana" has a range that is restricted at its western, northern and southern end by a line connecting Brisbane, QLD, and Canberra, ACT. Race "flava" is found in the Atherton Tablelands, QLD. Further to the South, in an area about half the East-West width of NSW ranging from central QLD to the South-East coast of VIC, race "modesta" is found (with the exception of the southern Alps). In years with good inland rainfall race "modesta" can disperse farther into the interior, adding the catchment of the Paroo River to its range. Yellow Thornbills can be found in various types of dry forest and woodland, usually dominated by cypress pines, eucalypts or various types of acacias.

Sightings Click here for sighting information Race "nana" B. Hensen reports spotting Yellow Thornbills, nominate race "nana", semi-regularly at St. Albans, NSW. They were found breeding at this location in December 2016. A. Campbell reports spotting Yellow Thornbills, nominate race "nana", semi-regularly at at Mount McEuen, QLD, near the north-western border of their range. Race "modesta" We see Yellow Thornbills, race "modesta", regularly at Eulah Creek, 20 km East of Narrabri, NSW, and elsewhere in the area (e.g. in the Pilliga scrub). V. Collins has also found Yellow Thornbills to be common eastward of Narrabri, NSW, e.g. along Bullawa Creek. C. Hayne reports seeing Yellow Thornbills, race "modesta", regularly in woodland near Moree, NSW, e.g. around Whittaker's Lagoon, 20 km West of Moree. Yellow Thornbills, race "modesta", have also been spotted by us in central western NSW, e.g. around Gilgandra, in October 2016.

Yellow Thornbills are furtive little birds that can be hard to find, because they tend to remain in trees (e.g. Cypress pines), mostly in shady areas, moving around quickly.

Yellow Thornbills are often seen by us foraging in trees together with other thornbills (mostly Inland Thornbills or Brown Thornbills).

Food, Diet

To the best of our knowledge all Thornbills feed on little insects that they pick off leaves. As shown in the photo below, this is at least true for Yellow Thornbills.
