The Asian fairy-bluebird (Irena puella) is a medium-sized, arboreal passerine bird. This fairy-bluebird is found in forests across tropical southern Asia, Indochina and the Greater Sundas. Two or three eggs are laid in a small cup nest in a tree. It was described by British ornithologist John Latham in 1790. The only other member of the genus and family is the Philippine fairy-bluebird, I. cyanogastra, which replaces the Asian fairy-bluebird in most of the Philippines. Both species are considered as sacred to the Tagalog people as they are perceived as tigmamanukan omens.
The adult Asian fairy bluebird is about 24 to 27 centimetres (9.4 to 10.6 in). The male has glossy, iridescent blue upperparts, and black underparts and flight feathers. The female and first year male are entirely dull blue-green.

GBIF citizen-science records
It is estimated from how often the Asian Fairy-bluebird is recorded against all the birds logged in Khao Yai National Park (1,723 verified sightings from 2019 to 2026), calibrated against known sighting rates.
