Rare
Under 5% of wildlife watchers report a White-bellied Green-Pigeon sighting in Taroko National Park on a given day, based on 57 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 95th most-seen of the 147 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.
April, June–July and September
In those months about 10% of wildlife watchers report a White-bellied Green-Pigeon in Taroko National Park on a given day, against under 5% in May, August and October–March, the lowest months.
Between 3 and 6 pm
Across all the parks we cover, that three-hour window holds the most White-bellied Green-Pigeon sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 3 parks where we can rate White-bellied Green-Pigeon sightings, Taroko National Park ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Nikko National Park (Japan, under 5%).
GBIF citizen-science records
It is estimated from how often the White-bellied Green-Pigeon is recorded against all the birds logged in Taroko 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.
