The striated thornbill (Acanthiza lineata) is a species of bird in the family Acanthizidae. It is endemic to Australia, where its natural habitat is subtropical or tropical dry forests. John Gould described the striated thornbill in 1838, giving it the common name of striated acanthiza. Alternative common names include striped-crowned thornbill or tit-warbler, striated tit-warbler or tit, and green thornbill.
The striated thornbill still bears its original name. A 2017 genetic study using both mitochondrial and nuclear DNA found that the ancestor of the striated thornbill diverged from that of the yellow thornbill around 6 million years ago.
Four subspecies are recognised. Acanthiza lineata alberti is found in southeast Queensland and is paler and more yellowish overall than the nominate subspecies. It has a bright orange-brown cap with prominent white streaks, and a yellow-olive back. There is a broad zone of intermediate birds stretching from Tenterfield south to Port Macquarie on the coast and Tamworth inland.
Acanthiza lineata lineata is found across New South Wales and Victoria, with a zone between the Grampians and Warrnambool, and the South Australian border where...

Rare
Under 5% of wildlife watchers report a Striated Thornbill sighting in Phillip Island Nature Park on a given day, based on 16 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 130th most-seen of the 149 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Striated Thornbill in Phillip Island Nature Park on a given day, so our monthly data shows no clear season.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Striated Thornbill sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
11th of 11
Of the 11 parks where we can rate Striated Thornbill sightings, Phillip Island Nature Park ranks 11th at under 5%. The best odds are in Blue Mountains National Park (Australia, about 40%), Flinders Chase (Australia, about 40%) and Kosciuszko National Park (Australia, about 30%). All parks ranked.
Same genus: Acanthiza
The closest relatives of the Striated Thornbill that you can see in Phillip Island Nature Park (genus Acanthiza, Australasian Thornbills) are Brown Thornbill (about 40%) and Yellow-rumped Thornbill (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Striated Thornbill is recorded against all the birds logged in Phillip Island Nature Park (16 verified sightings from 2019 to 2026), 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.
