Rare
Under 5% of wildlife watchers report a Pale-tailed Barbthroat sighting in Podocarpus National Park on a given day, based on 56 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 216th most-seen of the 446 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.
May
In that month about 20% of wildlife watchers report a Pale-tailed Barbthroat in Podocarpus National Park on a given day, against under 5% in June to March, the lowest months.

GBIF citizen-science records
It is estimated from how often the Pale-tailed Barbthroat is recorded against all the birds logged in Podocarpus National Park (56 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.
