With luck
About 10% of wildlife watchers report an Olive-backed Oriole sighting in Sydney on a given day, based on 1,896 verified sightings from GBIF citizen-science data. It is the 61st most-seen of the 243 birds we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
September to December
In those months about 20% of wildlife watchers report an Olive-backed Oriole in Sydney on a given day, against under 5% in February–March and May–July, the lowest months.

GBIF citizen-science records
It is estimated from how often the Olive-backed Oriole is recorded against all the birds logged in Sydney (1,896 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.
