The Common Iora (Linnaeus) is a small passerine bird found across the tropical Indian subcontinent with populations showing plumage variations. It feeds in pairs and is a very active bird.

Common Iora is common and widespread. Populations are not threatened. Its range is expanding due to creation of orchards and gardens, and it takes part in pest control in fruit orchards. Common Iora is a small bird living high up in the canopy. It is found in scrub and forests but avoides deep forests; it is easily detected from its loud whistles and the bright colours.

Ioras have a pointed and notched beak with a culmen that is straight. The common iora is sexually dimorphic males in the breeding season have a black cap and back adding to a black wing and tail at all seasons. Females have greenish wings and an olive tail. The undersides of both are yellow and the two white bars on the wings of the male are particularly prominent in their breeding plumage. It is found across the tropical Indian subcontinent.

Common Iora feeds mainly on insects such as grasshoppers, caterpillars, dragonflies and mantises. It also consumes spiders and small insects, fruit, berries and nectar.

During the breeding season, males display by fluffing up their feathers and spiral in the air appearing like a green, black, yellow and white ball. Male performs spectacular foreplay by an acrobatic act, darting up into the air fluffing up all his feathers, especially those on the pale green rump, then spiralling down to the original perch. Once he lands, he spreads his tail and droops his wings. Two to four greenish white eggs are laid in a small and compact cup-shaped nest made out of grass and bound with cobwebs and placed in the fork of a tree.

The call is a mixture of churrs, chattering and whistles, and the song is a trilled wheeeee-tee. They may sometimes imitate the calls of other birds such as Drongos.
