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.

コウカンチョウ

アカボウシインコチョウ（Paroaria coronata）はボリビア・ブラジルからアルゼンチンにかけての南アメリカ原産の、鮮やかな赤い冠羽、白い顔、灰色の体を持つ目を引く中型鳥類で、ハワイや太平洋の島々に移入されてホノルルの象徴的な庭鳥となった。密な低木、草地の端、郊外の庭に生息し、種子や小型昆虫を採食する。その名前や外見の類似性にもかかわらず、北米のショウジョウコウカンチョウとは近縁ではなく、フウキンチョウ科に属する。
