Pinzón Cactero Común, Pinzón de Cactus Común

<em>Geospiza scandens</em>, commonly known as the common cactus finch, is a bird species found in Ecuador and with records from Norway. It typically inhabits aerial, terrestrial, and aquatic environments, often closely associated with arid island ecosystems where cacti are prevalent. The species is classified as Least Concern on the IUCN Red List, indicating that it is not currently at risk of significant population decline at a global level. The common cactus finch belongs to the genus <em>Geospiza</em> within the family Thraupidae and is among the iconic Darwin's finches of the Galápagos Islands. It typically feeds on the nectar, pollen, and seeds of cactus plants, particularly <em>Opuntia</em>, and plays an important role as a pollinator and seed disperser within its island habitat. Biological traits such as average lifespan, body length, and mass of this species remain poorly documented in the scientific literature. Population trends are considered stable, and the species remains an important subject of evolutionary and ecological research.

Oso Polar

El mayor carnivoro terrestre de la Tierra, el oso polar puede superar los 700 kg y se encuentra en el hielo marino del Artico, desde Canada hasta Rusia. Es un mamifero marino altamente especializado que depende del hielo marino para cazar focas anilladas y barbadas. Excelente nadador capaz de cubrir grandes distancias en agua abierta. Clasificado como Vulnerable, sus poblaciones soportan una presion severa por la rapida perdida de hielo marino artico debida al cambio climatico.
