The asian fairy-bluebird is a small passerine bird species found in forests and plantations in tropical southern Asia. They are the sole members of the genus Irena and family Irenidae, and are related to the ioras and leafbirds.
These species eat fruit, especially figs, and possibly some insects. They lay two to three eggs in a tree nest.
The plumage of the fairy-bluebirds is exceptional, with the upperparts being deep rich blue. Although the fairy-bluebirds are highly visible in sunlight they are much less visible in the shade of the forest.
