Indian paradise flycatcher
Template:Short description Template:Speciesbox
The Indian paradise flycatcher (Terpsiphone paradisi) is a medium-sized passerine bird native to Asia, where it is widely distributed. As the global population is considered stable, it has been listed as Least Concern on the IUCN Red List since 2004. It is native to the Indian subcontinent, Central Asia and Myanmar.<ref name=iucn/>
Males have elongated central tail feathers, and a black and rufous plumage in some populations, while others have white plumage. Females are short-tailed with rufous wings and a black head.<ref name=owen1963/> Indian paradise flycatchers feed on insects, which they capture in the air often below a densely canopied tree.
TaxonomyEdit
The Indian paradise flycatcher was formally described in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his Systema Naturae under the binomial name Corvus paradisi.<ref>Template:Cite book</ref><ref>Template:Cite book</ref> The Indian paradise flycatcher is now one of 17 paradise flycatchers placed in the genus Terpsiphone that was introduced in 1827 by the German zoologist Constantin Gloger.<ref name=ioc>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> Paradise-flycatchers were formerly classified with the Old World flycatcher in the family Muscicapidae, but are now placed in the family Monarchidae together with monarch flycatchers.<ref>Template:Cite journal</ref><ref>Template:Cite journal</ref> Until 2015, the Indian paradise flycatcher, Blyth's paradise flycatcher, and the Amur paradise flycatcher were all considered conspecific, and together called Asian paradise flycatcher.<ref name=ioc/>
SubspeciesEdit
Three subspecies are recognized:<ref name=ioc/>
- T. p. paradisi (Linnaeus, 1758) breeds in central and southern India, central Bangladesh, and south-western Myanmar; populations occurring in Sri Lanka in the winter season are non-breeding.<ref name=rasmussen/>
- Himalayan paradise flycatcher (T. p. leucogaster) (Swainson, 1838) was initially described as a separate species. It breeds in the western Tian Shan, Afghanistan, northern Pakistan, and northwestern and central India, and western and central Nepal; populations in eastern Pakistan and in southern India migrate towards the foothills of the Himalayas in spring for breeding.<ref name=rasmussen>Template:Cite book</ref>
- Ceylon paradise flycatcher (T. p. ceylonensis) (Zarudny & Harms, 1912) occurs in Sri Lanka.
DescriptionEdit
Adult Indian paradise flycatchers are Template:Convert long. Their heads are glossy black with a black crown and crest, their black bill round and sturdy, and their eyes black. Females are rufous on the back with a greyish throat and underparts. Their wings are Template:Convert long. Young males look very much like females but have a black throat and blue-ringed eyes. As adults, they develop up to Template:Convert long tail feathers with two central tail feathers growing up to Template:Convert 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. Long-tailed rufous birds are generally devoid of shaft streaks on the wing and tail feathers, while in white birds the shaft streaks, and sometimes the edges of the wing and tail feathers are black.<ref name=owen1963>Template:Cite journal</ref>
In the early 1960s (before the recognition of Blyth's and Amur paradise flycatchers as separate species), 680 long-tailed males were examined that are contained in collections of the British Museum of Natural History, Chicago Natural History Museum, Peabody Museum, Carnegie Museum, American Museum of Natural History, United States National Museum, and Royal Ontario Museum. The specimens came from almost the entire range of the species, though some areas were poorly represented. The relative frequency of the rufous and white plumage types varies geographically. Rufous birds are rare in the extreme southeastern part of the species' range. Throughout the Indian area and, to a lesser extent, in China, asymmetrically patterned intermediates occur. Intermediates are rare or absent throughout the rest of the range of the species. In general, long-tailed males are<ref name=owen1963/>
- predominantly rufous with some white in wings and tail — collected in Turkestan, Kashmir, northern India, Punjab, Maharashtra, Sikkim, and in Sri Lanka;
- predominantly rufous with some white in wings — collected in Iran, Afghanistan, Baluchistan, Punjab, Kashmir, northern and central India, Rajasthan, Maharashtra, Bihar, and Nepal;
- predominantly rufous with some white in tail — collected in Punjab, northern and central India, Kolkata, Sri Lanka, and in the Upper Yangtze Valley in China;
- predominantly white with some rufous in tail and wings — collected in Kashmir, Maharashtra, Sichuan, and North China;
- predominantly white with some rufous in tail — collected in Maharashtra and Fuzhou, China;
- predominantly white with back partly rufous — collected in Punjab and Chennai;
- moulting from rufous into white plumage — collected in North Bihar.
Possible interpretations of this phenomenon are: males may be polymorphic for rufous and white plumage colour; rufous birds may be sub-adults; and there may even be two sympatric species distinguishable only in the male.<ref name=owen1963/>
Distribution and habitatEdit
_-_Sri_Lanka_-_01.jpg){kind=link}
The Indian paradise flycatcher is a migratory bird and spends the winter season in tropical Asia. In southern India and Sri Lanka especially the highlands and western parts of Sri Lanka, both locally breeding populations and visiting migrants occur in winter.<ref>Template:Cite journal</ref><ref>Template:Cite journal</ref>
Behaviour and ecologyEdit
Indian paradise flycatcher's breeding season lasts from May to July.<ref>Template:Cite book</ref> Being socially monogamous, both males and females 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.<ref>Template:Cite journal</ref> The nest is sometimes built in the vicinity of a breeding pair of drongos, which keep predators away.<ref>Template:Cite journal</ref> The female lays up to four eggs in a neat cup nest made with twigs and spider webs on the end of a low branch. Chicks hatch in about 21 to 23 days.<ref name="rasmussen" /> A case of interspecific feeding has been noted with paradise flycatcher chicks fed by Indian white-eyes.<ref>Template:Cite journal</ref>
