Bulbul Collarejo

<em>Spizixos semitorques</em>, the Collared Finchbill, is a bulbul in the family Pycnonotidae. This species is assessed as Least Concern on the IUCN Red List. It is native to eastern Asia, with its range including southeastern China, Taiwan, and adjacent areas. The Collared Finchbill inhabits forest edges, scrub, and bamboo thickets, and is typically found at middle to higher elevations. Members of the genus <em>Spizixos</em> are characterized by their thick, finch-like bills, which are adapted for feeding on hard-coated seeds and berries in addition to insects. The common name reflects both the collar-like markings on the plumage and the distinctive bill morphology. Diet, population estimates, population trend, and biological measurements including average length, weight, and lifespan are not specified in available records. Biological traits of this species remain poorly documented in the scientific literature. The species is associated with aerial, terrestrial, and aquatic environments within its range. Its Least Concern status indicates stable populations across its eastern Asian range.

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.
