Indian Paradise Flycatcher
The Indian paradise flycatcher (Terpsiphone paradisi) is a medium-sized passerine bird native to Asia that 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.
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. Indian paradise flycatchers feed on insects, which they capture in the air often below a densely canopied tree.
Three subspecies are recognized:
Himalayan paradise flycatcher (T. p. leucogaster) – (Swainson, 1838): Originally described as a separate species. Breeds in the western Tian Shan, in Afghanistan, in the north of Pakistan, in northwestern and central India, in Nepal’s western and central regions; populations occurring in the east of Pakistan and in the south of India migrate towards the foothills of the Himalayas in spring for breeding.
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.
Ceylon paradise flycatcher (T. p. ceylonensis) – (Zarudny & Harms, 1912): found in Sri Lanka.
Adult Indian paradise flycatchers are 19–22 cm (7.5–8.7 in) 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 86–92 mm (3.4–3.6 in) long. Young males look very much like females but have a black throat and blue-ringed eyes. As adults they develop up to 24 cm (9.4 in) long tail feathers with two central tail feathers growing up to 30 cm (12 in) 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.
In the early 1960s, 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
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, 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.
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.
According to Linné’s first description Indian paradise flycatchers were only distributed in India. Later ornithologists observed this spectacular bird in other areas, and based on differences in plumage of males described several subspecies.
Indian paradise flycatchers inhabit thick forests and well-wooded habitats from Central Asia to south-eastern China, all over India and Sri Lanka to Myanmar.
Indian 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.
The breeding season lasts from May to July. 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. Three or four eggs are laid in a neat cup nest made with twigs and spider webs on the end of a low branch. The nest is sometimes built in the vicinity of a breeding pair of drongos, which keep predators away. Chicks hatch in about 21 to 23 days. A case of interspecific feeding has been noted with paradise flycatcher chicks fed by Oriental white-eyes.

The Polymorphic Plastic Parade (Tipi tour 09), www.plasticparade.org/ came to Austin. The members of the project had a discussion about the project at the MASS Gallery.
This was very interesting. It was a great idean and I enjoyed discovering how the idea came about and how they accomplished it.
POISONOUS
All parts of the plant are poisonous, containing cyanogenic glycosides(hydrogen cyanide). In small quantities, hydrogen cyanide has been shown to stimulate respiration and improve digestion, it is also claimed to be of benefit in the treatment of cancer. In excess, however, it can cause respiratory failure and even death. This species is polymorphic for cyanogenic glycosides. The flowers of some forms of the plant contain traces of prussic acid and so the plants can become mildly toxic when flowering. They are completely innocuous when dried.
No known Edible uses.
MEDICINAL USES: Anti-inflammatory; Antispasmodic; Cardiotonic; Carminative; Febrifuge; Hypoglycemic; Restorative; Sedative;
Tonic; Vermifuge.
Carminative, febrifuge, hypoglycemic, restorative, vermifuge. The flowers are antispasmodic, cardiotonic and sedative. The root is carminative, febrifuge, restorative and tonic. The plant is used externally as a local anti-inflammatory compress in all cases of skin inflammation.
OTHER USES: Dye; Green manure.
An orange-yellow dye is obtained from the flowers. A useful green manure plant, fixing atmospheric nitrogen. It is difficult to see this plant as a useful green manure, it is fairly slow growing and does not produce much bulk

Coronavirus-like Particle Cryo-ET-Cryo-electron tomography (cryo-ET) is an approach for resolving polymorphic structures such as cells and organelles in a near-natural state and can provide a three-dimensional (3D) snapshot of viral particles in the host cell environment. The cryo-electron microscopy (cryo-EM) single-particle analysis (SPA) technology is usually utilized to study single particles, mainly macromolecular complexes or viral particles with regular shapes that have been isolated and purified by biochemical methods. Creative Biostructure provides cryo-ET services that allow you to obtain structural information about viral particles, as well as their spatial arrangement in the cell/tissue environment and view their interaction with other molecules in vivo.
