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.

Comoro Drongo

<em>Dicrurus fuscipennis</em>, the Comoro drongo, is a passerine bird in the family Dicruridae, endemic to the Comoro Islands in the western Indian Ocean, primarily found on the island of Grande Comore. The species inhabits humid montane forest and forest edge habitats, particularly in the interior upland areas of the island where native forest cover persists. Like other drongos, it is an active and aggressive insectivore that typically perches prominently on exposed branches before sallying out to catch flying insects, a foraging behavior known as aerial hawking. Biological traits such as precise average lifespan, body length, and body weight remain poorly documented in consolidated scientific literature for this restricted endemic species. The Comoro drongo is largely glossy black with a slightly forked tail, resembling other drongo species in the region. Its restricted range and dependence on intact native forest make it highly vulnerable to ongoing deforestation on Grande Comore, where forest clearance for agriculture and fuel continues to reduce available habitat. <em>Dicrurus fuscipennis</em> is assessed as Endangered by the IUCN, reflecting its small population size, restricted range, and accelerating habitat loss driven by human land use on the island.
