Alción colilargo común

<em>Tanysiptera galatea</em> is a strikingly colored kingfisher in the family Alcedinidae, native to the Maluku Islands and New Guinea in the Australasian region. The species is characterized by elongated central tail feathers, a vivid blue and white plumage, and a distinctive red bill. It inhabits lowland tropical forests, forest edges, and secondary growth, where it forages for invertebrates, small lizards, and earthworms typically caught by diving to the ground from low perches. The species nests in arboreal termite mounds, excavating tunnel nests that provide insulation and protection. Its occurrence record in Norway is a clear database artifact; the true range is confined to the islands of eastern Indonesia and New Guinea. The IUCN classifies this species as Least Concern owing to its broad distribution and large populations across suitable forest habitats. Biological traits including average lifespan, body length, and body weight are not consistently recorded across populations in standardized databases, and detailed dietary data remain poorly documented. Conservation concerns center on the continued integrity of lowland forests within its range, particularly in areas facing agricultural conversion and logging pressure.

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.
