Coastal Miner

Geositta peruviana, the coastal miner, is a small passerine bird in the family Furnariidae native to the hyperarid coastal desert of Peru, one of the driest places on Earth. The species inhabits the Atacama and Peruvian coastal desert zone, occurring along the entire Peruvian coast from sea level up to several hundred meters elevation on the coastal slopes of the western Andes, where sparse vegetation and sandy or rocky substrate provide nesting and foraging habitat. Miners in the genus Geositta are ground-dwelling birds that excavate nest tunnels in sandy banks and flat ground, laying eggs at the end of the tunnel in a grass-lined chamber. The coastal miner forages on bare ground and among sparse desert vegetation for small insects, seeds, and invertebrates. It is part of a guild of small ground birds highly specialized to the Peruvian coastal desert, which despite its extreme aridity supports a unique assemblage of endemic vertebrates. The species is assessed as Least Concern by the IUCN, being relatively common and widespread throughout its desert coastal range. The Furnariidae, the ovenbirds, are one of the most diverse bird families in South America, comprising over 300 species that have radiated into an extraordinary range of habitats and ecological niches across the continent.

Polar bear

지구상에서 가장 큰 육상 육식동물인 북극곰은 700kg을 넘을 수 있으며 캐나다에서 러시아까지 북극 해빙 전역에 분포한다. 고리 물범과 수염 물범을 사냥하기 위해 해빙에 의존하는 고도로 특수화된 해양 포유류이다. 광활한 거리를 헤엄쳐 다닐 수 있는 뛰어난 수영 실력을 가지고 있다. 취약종으로 등재되어 있으며, 기후 변화로 인한 급격한 북극 해빙 감소로 심각한 압력을 받고 있다.
