Ardilla Gris Oriental

Native to eastern North America but successfully introduced to Europe and other regions, the eastern gray squirrel is a medium-sized arboreal rodent weighing up to 600 g. Highly adaptable, thriving in forests, parks, and urban gardens, gray squirrels cache thousands of nuts and seeds each autumn, inadvertently planting trees through forgotten caches. In Britain, they have largely displaced the native red squirrel by outcompeting them for food.

Collared Grosbeak

<em>Mycerobas affinis</em>, the Collared Grosbeak, is a large finch in the family Fringillidae. This species is assessed as Least Concern on the IUCN Red List. It is native to the Himalayan region and adjacent mountain ranges of South and East Asia, inhabiting montane forests, particularly coniferous and mixed forests at high elevations. Members of the genus <em>Mycerobas</em> are robust birds with powerful bills adapted for cracking open large seeds and hard-coated fruits. The Collared Grosbeak is named for the yellow or greenish collar visible in male plumage. The species is typically encountered in flocks, often foraging in the forest canopy and shrub layer. Diet includes seeds, berries, and invertebrates, though specific diet data for <em>Mycerobas affinis</em> are not enumerated in the available records. Biological measurements such as average length, weight, and lifespan are not specified in available data. Biological traits of this species remain poorly documented in the scientific literature. Its Least Concern status reflects stable populations across its broad Himalayan and montane Asian range.
