Oriental Magpie Robin

The oriental magpie-robin (Copsychus saularis) is a small passerine bird that was formerly classed as a member of the thrush family Turdidae, but now considered an Old World flycatcher. They are distinctive black and white birds with a long tail that is held upright as they forage on the ground or perch conspicuously. Occurring across most of the Indian subcontinent and parts of Southeast Asia, they are common birds in urban gardens as well as forests. They are particularly well known for their songs and were once popular as cagebirds. The oriental magpie-robin is the national bird of Bangladesh. The diet  includes mainly insects and other invertebrates. Although mainly insectivorous, they are known to occasionally take flower nectar, geckos, leeches, centipedes and even fish.They are often active late at dusk. They sometimes bathe in rainwater collected on the leaves of a tree.
Magpie robins breed mainly from March to July in India and January to June in south-east Asia. Males sing from high perches during courtship. The display of the male involves puffing up the feathers, raising the bill, fanning the tail and strutting. They nest in tree hollows or niches in walls or building, often adopting nest boxes. They line the cavity with grass. The female is involved in most of the nest building, which happens about a week before the eggs are laid. Four or five eggs are laid at intervals of 24 hours and these are oval and usually pale blue green with brownish speckles that match the color of hay. The eggs are incubated by the female alone for 8 to 14 days.
