The Taiwan green pigeon or whistling green pigeon (Treron formosae) is a bird in the family Columbidae. The species was first described by Robert Swinhoe in 1863. It is found in Taiwan and Batanes in the Philippines. Its natural habitats are subtropical or tropical moist lowland forests and rural gardens. It is threatened by habitat loss.
The Ryukyu green pigeon (T. permagnus) of the Ryukyu Islands was formerly considered conspecific, with both species being united together as the whistling green pigeon, but was split as a distinct species by the IOC in 2021.
There are thought to be two subspecies: T. f. filipinus - endemic to the Philippines, found on Batanes and the Babuyan Islands The Taiwan green pigeon is visually similar to the Wedge-tailed green pigeon, but with usually darker plumage. Females are of various green shades throughout, and males have a distinctive purple-grey patch over the wings.
It inhabits subtropical broadleaved evergreen forest, cultivated fields where there are trees nearby, mainly lowlands and hills on small islands but is mainly a montane species... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Whistling Green-Pigeon is recorded against all the birds logged in Naha (13 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.
