Zorzal-palmero Acollarado

The Collared Palm Thrush, known scientifically as <em>Cichladusa arquata</em>, is a passerine bird belonging to the family Muscicapidae, the Old World flycatchers. <em>Cichladusa arquata</em> is a notable singer, often characterised by its melodic and varied song delivered from prominent perches. The species typically inhabits woodland, thicket, and savanna habitats, often in areas with scattered trees or dense shrubbery, including areas near human habitation. As the common name suggests, the species is often associated with palm groves and similar vegetation types. 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 Palm Thrush is currently assessed as Least Concern on the IUCN Red List, reflecting a stable global population without significant conservation concerns.

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.
