With luck
About 10% of wildlife watchers report a Chestnut-breasted Munia sighting in Brisbane on a given day, based on 2,046 verified sightings from GBIF citizen-science data. It is the 71st most-seen of the 237 birds we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
December to April
In those months about 20% of wildlife watchers report a Chestnut-breasted Munia in Brisbane on a given day, against about 10% in May to November, the lowest months. Those are among Brisbane's wettest months, with about 130 mm of rain a month against 40 mm in July.
Between 2 and 5 pm
Across all the parks we cover, that three-hour window holds the most Chestnut-breasted Munia sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Only Brisbane, in our data
Brisbane is the only city on Wallace's Line with enough records to rate Chestnut-breasted Munia sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Chestnut-breasted Munia is recorded against all the birds logged in Brisbane (2,046 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.
