Dajal-Elsterdrossel

Bestimmung

The oriental magpie-robin is 19 centimetres (7.5 in) long, including the long tail, which is usually held cocked upright when hopping on the ground. When they are singing a song the tail is normal like other birds. It is similar in shape to the smaller European robin, but is longer-tailed. The male has black upperparts, head and throat apart from a white shoulder patch. The underparts and the sides of the long tail are white. Females are greyish black above and greyish white under. Young birds have scaly brown upperparts and head.<p>The nominate race is found on the Indian subcontinent and the females of this race are the palest. The females of the Andaman Islands race andamanensis are darker, heavier-billed and shorter-tailed. The Sri Lankan race ceylonensis (formerly included with the peninsular Indian populations south of the Kaveri River) and southern nominate individuals have the females nearly identical to the males in shade. The eastern populations, the ones in Bangladesh and Bhutan, have more black on the tail and were formerly named erimelas. The populations in Myanmar (Burma) and further south are named as the race musicus. A number of other races have been named across the range, including prosthopellus (Hong Kong), nesiotes, zacnecus, nesiarchus, masculus, pagiensis, javensis, problematicus, amoenus, adamsi, pluto, deuteronymus and mindanensis. However, many of these are not well-marked and the status of some of them is disputed. Some, like mindanensis, have now been usually recognized as a full species (the Philippine magpie-robin). There is more geographic variation in the plumage of females than in that of the males.<p>It is mostly seen close to the ground, hopping along branches or foraging in leaf-litter on the ground with a cocked tail. Males sing loudly from the top of trees or other high perches during the breeding season.

Verhalten

collection<p>Oriental 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.[citation needed]<p>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.<p>The diet of magpie-robins includes mainly insects and other invertebrates. Although mainly insectivorous, they are known to occasionally take flower nectar, geckos, leeches, centipedes and even fish.<p>They are often active late at dusk. They sometimes bathe in rainwater collected on the leaves of a tree.
