A number of subspecies are recognized within its widespread range in South Asia and Southeast Asia. The nominate race is from the lowlands of Sri Lanka. Race O. s. fernandonis is found in the highlands of Sri Lanka. Neighbouring India has O.s. guzuratus in the peninsula and west to Pakistan while towards the north O. s. patia is found in the Terai of Nepal along the Himalayan foothills until Myanmar. A small population of O. s. patia is also found in the northern Eastern Ghats (Wangasara). The hills of northeastern India have O. s. luteus. In Southeast Asia O. s. inexpectatus and O. s. maculicollis are found in Thailand, Laos and Vietnam, Malaysia, Cambodia and Vietnam. South east China, including the island of Hainan, and Tonkin in Vietnam have O. s. longicauda while O. s. edela is found on Java.
The Common Tailorbird is a brightly coloured bird, with bright green upperparts and whitish underparts. They range in size from [.9 and weigh [.21. They have short rounded wings, a long tail, strong legs and a sharp bill with curved tip to the upper mandible. They are wren-like with a long upright tail that is often moved around. The crown is rufous and the upperparts are predominantly olive green. The underside is creamy white. The sexes are identical, except that the male has long central tail feathers in the breeding season, although the reliability of sexing data accompanying museum specimens used in determining this sexual dimorphism has been questioned. Young birds are duller. When calling, the dark patches on the sides of the neck become visible. These are due to the dark pigmented and bare skin that are present in both sexes and sometimes give the appearance of a dark gorget.
Tailorbirds are found in singly or in pairs, usually low in the undergrowth or trees sometimes hopping on the ground. They forage for insects and have been known to feed on a range of beetles and bugs. They are attracted to insects at flowers and are known to favour the inflorescenses of mango. They also visit flowers such as those of Bombax, Salmalia for nectar and are sometimes covered in pollen, giving them a golden-headed appearance.
The breeding season is March to December peaking from June to August in India, coinciding with the wet season. In Sri Lanka the main breeding periods are March to May and August to September, although they can breed throughout the year.
The nest is a deep cup, lined with soft materials and placed in thick foliage and the leaves holding the nest have the upper surfaces outwards making it difficult to spot. The punctures made on the edge of the leaves are minute and do not cause browning of the leaves, further aiding camouflage. The stitch is made by piercing two leaves and drawing fibre through them. The fibres fluff out on the outside and in effect they are more like rivets.
The incubation period is about 12 days. Both male and female feed the young. Mortality of eggs and chicks is high due to predation by rodents, cats, crow-pheasants, lizards and other predators. The young birds fledge in about 14 days. The female alone incubates according to some sources, while others suggest that both sexes incubate; however, both parents take part in feeding and sanitation.
