8-3-2020 PERIYAR RIVER LODGE, INDIA - ORIENTAL MAGPIE ROBIN (Copsychus saularis)


This magpie-robin is a resident breeder in tropical southern Asia from Nepal, Bangladesh, India, Sri Lanka and eastern Pakistan, eastern Indonesia, Thailand, south China, Malaysia, and Singapore.

The Oriental magpie-robin is found in open woodland and cultivated areas often close to human habitations.

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. The nests are said to have a characteristic odour.

Females spend more effort on feeding the young than males. Males are quite aggressive in the breeding season and will defend their territory. They respond to the singing of intruders and even their reflections. Males spend more time on nest defense. Studies of the bird song show dialects with neighbours varying in their songs. The calls of many other species may be imitated as part of their song. This may indicate that birds disperse and are not philopatric. Females may sing briefly in the presence of a male. Apart from their song, they use a range of calls including territorial calls, emergence and roosting calls, threat calls, submissive calls, begging calls and distress calls. The typical mobbing calls is a harsh hissing krshhh.
