The chestnut-rumped heathwren (Hylacola pyrrhopygia) is a species of bird in the family Acanthizidae. It is endemic to temperate and subtropical forests and heathlands of Australia.

With luck
About 10% of wildlife watchers report a Calamanthus pyrrhopygius sighting in Great Otway National Park on a given day, based on 143 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 98th most-seen of the 175 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 30%, if each day is a fresh chance.
January, March, June and August–October
In those months about 10% of wildlife watchers report a Calamanthus pyrrhopygius in Great Otway National Park on a given day, against under 5% in February, April–May, July and November–December, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Calamanthus pyrrhopygius sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 4 parks where we can rate Calamanthus pyrrhopygius sightings, Great Otway National Park has the highest daily chance: about 10%. Next come Royal National Park (Australia, about 10%) and Grampians National Park (Australia, under 5%).
GBIF citizen-science records
It is estimated from how often the Calamanthus pyrrhopygius is recorded against all the birds logged in Great Otway National Park (143 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.
