Brown-breasted Flycatcher (Muscicapa muttui) provides one of the best examples of passage migration (aside from the true passage migrants) within the Indian Subcontinent.
It breeds in East Asia and the northern parts of Southeast Asia and migrates westwards and southwards to winter mainly in the Western Ghats and Sri Lanka. During both onward and return passage, Brown-breasted Flycatcher can be seen in wooded areas across peninsular India, but is seen in especially good numbers in West Bengal and Bangladesh during spring.
