Reproductive biology

In India, the common iora may nest from May to September varying slightly with locale, while Marshall's iora, with its dryer range in Pakistan and northwest India, only breeds from June to August. Ioras have a well-known courtship display, which makes a vibrant spectacle of the normally inconspicuous male. During the display the male begins by chasing the female. Then it perches, wings lowered, and fluffs up its lower back feathers, lifts its tail and issues its call, long-drawn hissing phrases. Periodically it jumps up above its perch with its white back feathers fluffed and glides slowly back to its perch in a spiral while calling, sounding like a cricket or tree frog. Iora nests are deep, well constructed cups covered on the outside with spider webs, situated three or four meters up in a tree fork. The clutch is usually two to four gray, brown, or purplish streaked pinkish white eggs.

In India, the blue-winged leafbird (Chloropsis cochinchinen-sis) nests chiefly from April to August, while the goldenfronted leafbird (C. aurifrons) commences a month later, but also breeds until August. The courtship of the latter appears confrontational, with the male and female chasing and screeching at each other. The nest is a loosely formed cup composed of runners, moss, and rootlets weakly held together with spider webs. Chloropsis eggs are typically pale, speckled or flecked with black and various other colors.

Wild fairy bluebirds (Irena puella) have a short breeding period, typically from February to April (captive birds may breed from April through October). The nest is a loose platform of twigs, overlaid by moss, roots, and detritus, hidden in leafy trees at least five meters up. The usual clutch is of two eggs, olive-gray, irregularly splotched with brown.
