Nördlicher Grauerdhacker

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.

Kaiserpinguin

The world's largest penguin, emperor penguins stand up to 1.2 meters and weigh 45 kg, inhabiting the Antarctic continent in some of the most extreme conditions on Earth. They breed in midwinter darkness at temperatures below -60°C, with males incubating single eggs on their feet under a brood pouch for 65 days while females are at sea. Their huddling behavior — cycling individuals through the warm center of thousands-strong groups — is a masterclass in cooperative survival.
