Rare
Under 5% of wildlife watchers report a Hartert's Leaf-Warbler sighting in Hong Kong on a given day, based on 41 verified sightings from GBIF citizen-science data. It is the 106th most-seen of the 204 birds we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the Hartert's Leaf-Warbler is recorded against all the birds logged in Hong Kong (41 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.
