Rare
Under 5% of wildlife watchers report a Little Woodstar sighting in Podocarpus National Park on a given day, based on 57 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 212th 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.
October
In that month about 20% of wildlife watchers report a Little Woodstar in Podocarpus National Park on a given day, against under 5% in November to September, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Little Woodstar sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Podocarpus National Park, in our data
Podocarpus National Park is the only park on Wallace's Line with enough records to rate Little Woodstar sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Little Woodstar is recorded against all the birds logged in Podocarpus National Park (57 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.
