Rare
Under 5% of wildlife watchers report a Large-billed Scrubwren sighting in Blue Mountains National Park on a given day, based on 199 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 85th most-seen of the 196 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
December
In that month about 10% of wildlife watchers report a Large-billed Scrubwren in Blue Mountains National Park on a given day, against under 5% in January to November, the lowest months.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Large-billed Scrubwren sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
6th of 6
Of the 6 parks where we can rate Large-billed Scrubwren sightings, Blue Mountains National Park ranks 6th at under 5%. The best odds are in Lamington National Park (Australia, about 50%), Springbrook National Park (Australia, about 30%) and Royal National Park (Australia, about 10%).
GBIF citizen-science records
It is estimated from how often the Large-billed Scrubwren is recorded against all the birds logged in Blue Mountains National Park (199 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.
