Oriental Magpie-Robin

Description:

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.This species is 19 centimetres (7.5 in) long, including the long tail that is usually held cocked upright. 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. Young birds have scaly brown upperparts and head. It is the national bird of Bangladesh.

Habitat:

Distributed in most of the Indian Subcontinent and parts of Southeast Asia, they are common birds in urban gardens as well as forests.

Notes:

These Birds are the real "Early Birds", getting active at about 4 a.m. They are observed to be active at dusk too. Can anyone explain the reason behind it?
