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.

Mexican Violetear

멕시코제비꽃귀벌새는 중형 크기로 주로 녹색 깃털을 띠며 독특한 금속성 보라빛-파란색 귀 패치와 흉부 줄무늬가 있다. 멕시코에서 중앙아메리카까지 해발 1,000~3,000m의 고지대 및 산악 숲에 서식한다. 수컷은 공격적이고 매우 소리가 많으며 화려한 비행 과시를 펼친다. 고고도에서 번식하지만 일부 개체군은 계절적 고도 이동을 한다. 멕시코 고지대 소나무-참나무 숲과 구름 숲에서 가장 흔한 벌새 중 하나다.
