Capuchino Castaño

El capuchino ventricastaño es un pequeño pinzón estríldido robusto con plumaje marrón rojizo intenso, cabeza negra y vientre blanco, que habita praderas, arrozales y bordes de bosques abiertos desde India y Sri Lanka hacia el este a través del Sudeste Asiático hasta Filipinas y Taiwán. Muy gregario, forma grandes bandadas y a veces se considera una plaga agrícola menor en los cultivos de arroz. Ampliamente mantenido como ave de aviario en toda Asia, son relativamente fáciles de criar y mantener en cautiverio.

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.
