The ioras are a small family of four species found in south and southeast Asia. The leafbirds are a family of small passerine bird species found in the Indian Subcontinent and Southeast Asia. Both these were formerly grouped together with fairy-bluebirds in the family Irenidae. Bulbuls are distributed across most of Africa and into the Middle East, tropical Asia to Indonesia, and north as far as Japan. A few insular species occur on the tropical islands of the Indian Ocean.
