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.

Golden Eagle

세계에서 가장 강력하고 널리 분포하는 맹금류 중 하나인 검독수리는 날개 폭이 2.2m에 달하며 북반구 전역의 산악 지형에 서식한다. 뛰어난 공중 사냥꾼으로 활공 비행과 시속 200km 이상의 가파른 강하를 이용해 토끼, 산토끼, 땅다람쥐, 때로는 어린 사슴과 여우를 포획한다. 많은 문화권에서 수천 년에 걸친 매사냥 전통의 중심에 있어 왔다.
