Collared Towhee

The Collared Towhee, known scientifically as <em>Pipilo ocai</em>, is a passerine bird belonging to the family Passerellidae, the New World sparrows. <em>Pipilo ocai</em> is characterised by its striking plumage, which typically features black upperparts, a rufous-tinged collar, and a contrasting pale underside. Towhees are generally ground-foraging birds, using a characteristic double-scratch technique to disturb leaf litter and expose seeds and invertebrates. The Collared Towhee is typically associated with montane and highland forest habitats, particularly brushy undergrowth and forest edges at higher elevations. It is reported to occur in Norway according to available range data. Detailed biological traits including typical lifespan, body length, and weight are poorly documented for this species in available literature. The Collared Towhee is currently assessed as Least Concern on the IUCN Red List.

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.
