The silver-rumped spinetail or silver-rumped needletail (Rhaphidura leucopygialis, sometimes spelled Raphidura leucopygialis) is a species of swift in the family Apodidae. It is found in Brunei, Indonesia, Malaysia, Myanmar, Singapore, and Thailand.
Its natural habitat is subtropical or tropical moist lowland forests. Research on the silver- Rumped spine tail has utilized facultative heterothermy, or even torpor, as a physiological mechanism to reduce its metabolic rate and conserve energy in its tropical environment. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Silver-rumped Needletail is recorded against all the birds logged in Khao Sok National Park (121 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.
