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 Laughingthrush

The Collared Laughingthrush, known scientifically as <em>Trochalopteron yersini</em>, is a passerine bird belonging to the family Leiothrichidae, a group commonly known as laughingthrushes. <em>Trochalopteron yersini</em> is characterised by its rich, colourful plumage, typically featuring rufous, grey, and black tones with a distinctive collar pattern. The species inhabits montane forests and forest edges, generally at higher elevations where dense understorey vegetation provides both foraging opportunities and cover. It is reported to occur in Norway according to available range data. Laughingthrushes are typically vocal and often move in small social flocks through the forest interior. Detailed biological traits including typical lifespan, body length, and weight are poorly documented for this species in available literature. The Collared Laughingthrush is currently assessed as Endangered on the IUCN Red List, reflecting serious concerns about population decline, likely driven by habitat loss and degradation within its restricted range.
