Rare
Under 5% of wildlife watchers report a Philippine Swiftlet sighting in Manila on a given day, based on 11 verified sightings from GBIF citizen-science data. It is the 180th most-seen of the 191 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 Philippine Swiftlet in Manila on a given day, so our monthly data shows no clear season.
Among the best
Of the 2 cities where we can rate Philippine Swiftlet sightings, Manila ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Davao City (Philippines, under 5%).
GBIF citizen-science records
It is estimated from how often the Philippine Swiftlet is recorded against all the birds logged in Manila (11 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.
