Range

Widely distributed across Asia (Taiwan), Europe (5 countries), North America (United States), and South America (Colombia, Ecuador, Venezuela).

Complex-toothed Flying Squirrel

Habitat

Typically found in diverse terrestrial and aquatic ecosystems.

Blue-and-yellow Macaw

One of the most striking and widely kept macaw species, blue-and-yellow macaws display brilliant cobalt blue upper parts contrasting with vivid yellow underparts and green forehead. They inhabit forest, woodland, and savanna from eastern Panama through Venezuela, Brazil, and Bolivia to Peru and Ecuador. Highly intelligent, they live in pairs or small flocks, feeding on palm nuts, seeds, and fruit. Popular in aviculture for over 400 years, they can live 80+ years in captivity.

Complex-toothed Flying Squirrel

<em>Trogopterus xanthipes</em>, the complex-toothed flying squirrel, is a medium-sized gliding rodent in the family Pteromyidae endemic to China, where it inhabits montane broadleaf and mixed forests at elevations typically between 1,000 and 2,700 metres in provinces including Sichuan, Yunnan, Guizhou, Hubei, and neighbouring regions. This species is the sole member of the genus Trogopterus and is distinguished by complex tooth morphology compared to other flying squirrels. Like all flying squirrels, it possesses a patagium — a gliding membrane stretching between fore and hind limbs — that enables it to glide between trees rather than undertake powered flight. The complex-toothed flying squirrel is nocturnal and arboreal, spending its days sheltering in tree hollows and foraging at night for leaves, bark, seeds, and fungi. Its faeces, known as Wuflingzhi, have been used in traditional Chinese medicine for centuries, leading to trapping pressure in parts of its range. The IUCN classifies this species as Near Threatened, reflecting population decline driven by overhunting for medicinal use and ongoing habitat loss from logging and agricultural encroachment in montane forests. Biological traits including average body mass, lifespan, litter size, and home range are partially documented but detailed population estimates are limited. Conservation measures include legal protections under Chinese wildlife law.
