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.

Rare
Under 5% of wildlife watchers report a Calamanthus pyrrhopygius sighting in Sydney on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 230th most-seen of the 243 birds we can rate there. Over three days the chance rises to under 5%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Calamanthus pyrrhopygius in Sydney on a given day, so our monthly data shows no clear season.
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.
Only Sydney, in our data
Sydney is the only city on Wallace's Line with enough records to rate Calamanthus pyrrhopygius sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Acanthizidae
The closest relatives of the Calamanthus pyrrhopygius that you can see in Sydney (family Acanthizidae, Thornbills and Allies) are White-browed Scrubwren (about 20%), Brown Thornbill (about 10%) and Yellow Thornbill (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Calamanthus pyrrhopygius is recorded against all the birds logged in Sydney (7 verified sightings), 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.
