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.

Cardenilla crestada

El cardenal crestirojo (Paroaria coronata) es un ave mediana llamativa, con brillante cresta roja, cara blanca y cuerpo gris. Es originaria de Sudamerica, desde Bolivia y Brasil hasta Argentina, y ha sido introducida en Hawaii y otras islas del Pacifico, donde se ha convertido en un ave emblematica de los jardines de Honolulu. Habita arbustos densos, bordes de pastizales y jardines suburbanos, donde se alimenta de semillas e insectos pequenos. A pesar de su nombre y parecido superficial, no esta emparentada con los cardenales norteamericanos, sino que pertenece a la familia de los tangaras.
