According to Linné’s first description Asian Paradise Flycatchers were only distributed in India. Later ornithologists observed this spectacular bird in other এছিয়াn countries, and based on differences in plumage of males described several subspecies, of which the following 14 are recognized today:^২

• T. p. paradisi (Linnaeus, 1758) breeds in central and southern India, central বাংলাদেশ and south-western ম্যানমাৰ; populations occurring in Sri Lanka in the winter season are non-breeding.^৩
• T. p. leucogaster (Swainson, 1838) breeds in the western Tian Shan, in আফগানিস্তান, in the north of পাকিস্তান, in northwestern and central India, in নেপাল’s western and central regions; populations occurring in the east of Pakistan and in the south of India migrate towards the foothills of the হিমালয় in spring for breeding.^৩
• T. p. affinis (Blyth, 1846) inhabits মালয়েছিয়া and Sumatra.
• T. p. incei (Gould, 1852) breeds in eastern, northeastern and central চীন, in the Russian Far East and in the north of Korea; populations occurring in Southeast Asia are non-breeding.
• T. p. insularis (Salvadori, 1887) inhabits the island Nias off the western coast of Sumatra.
• T. p. nicobarica (Oates, 1890) inhabits the Nicobar Islands.
• T. p. sumbaensis (Meyer, 1894) inhabits the Lesser Sunda Island Sumba.
• T. p. floris (Büttikofer, 1894) inhabits the Lesser Sunda Islands Sumbawa, Flores, Lomblen and Alor Island.
• T. p. procera (Richmond, 1903) inhabits the island Simeuluë northwest off the coast of Sumatra.
• T. p. ceylonensis (Zarudny & Harms, 1912) inhabits Sri Lanka.
• T. p. borneensis (Hartert, 1916) inhabits Borneo.
• T. p. saturatior (Salomonsen, 1933) breeds in the eastern parts of Nepal and northeastern India, in eastern বাংলাদেশ and northern ম্যানমাৰ; populations occurring in মালয়েছিয়া migrate northward for breeding.^৩
• T. p. burmae (Salomonsen, 1933) inhabits the central region of Myanmar.
• T. p. indochinensis (Salomonsen, 1933) inhabits the eastern regions of Myanmar, Yunnan in the south of China, migrates through থাইলেণ্ড and Indochina to Malaysia, Sumatra and the neighboring islands.

বিৱৰণ

Adult Asian Paradise Flycatchers are 19 – long. Their heads are glossy black with a black crown and crest, their black bill round and sturdy, their eyes black. Female are rufous on the back with a greyish throat and underparts. Their wings are 86 – long. Young males look very much like females but have a black throat and blue-ringed eyes. As adults they develop up to 24 চে.মি. long tail feathers with two central tail feathers growing up to 30 চে.মি. long drooping streamers.

Young males are rufous and have short tails. They acquire long tails in their second or third year. Adult males are either predominantly bright rufous above or predominantly white. Some specimens show some degree of intermediacy between rufous and white. ^৪The relative frequency of the rufous and white plumage types varies geographically.

Asian Paradise-flycatchers inhabit thick forests and well-wooded habitats from Turkestan to Manchuria, all over ভাৰত and শ্ৰীলংকা to the Malay Archipelago on the islands of Sumba and Alor.^২

They are migratory and spend the winter season in tropical Asia. There are resident populations in southern India and Sri Lanka, hence both visiting migrants and the locally breeding subspecies occur in these areas in winter.^৫৬

, ভাৰত]]

Asian Paradise Flycatchers are noisy birds uttering sharp skreek calls. They have short legs and sit very upright whilst perched prominently, like a Shrike. They are Insectivorous and hunt in flight in the understorey. In the afternoons they dive from perches to bathe in small pools of water.

প্ৰজনন

The breeding season lasts from May to July.^৭ Being socially Monogamous both male and female take part in nest-building, incubation, brooding and feeding of the young. The incubation period lasts 14 to 16 days and the nestling period 9 to 12 days.^৮ Three or four eggs are laid in a neat cup nest made with twigs and spider webs on the end of a low branch.^৩
