Ballena azul

El animal más grande que se conoce haya vivido en la Tierra; las ballenas azules pueden alcanzar 33 metros y 200 toneladas — sus corazones solos pesan tanto como un automóvil pequeño. Se encuentran en todos los océanos y migran entre las zonas de alimentación polares y las áreas de reproducción tropicales. Son filtradoras que consumen hasta 4 toneladas de kril al día. En peligro de extinción, con poblaciones globales estimadas entre 10.000 y 25.000 tras casi extinguirse por la caza de ballenas en el siglo XX.

Tapaculo Chucao

The Chucao Tapaculo (Scelorchilus rubecula) is a secretive, ground-dwelling bird in the family Rhinocryptidae (tapaculos), endemic to the temperate Valdivian rainforests of southern Chile and adjacent Argentina. This robust, short-tailed bird has rich rufous-chestnut underparts and a barred or mottled brown upperside, blending into the dense leaf litter and fern undergrowth of southern beech (Nothofagus) and mixed Valdivian forest where it lives. The species is named for its far-carrying, repetitive call — a loud series of notes that rings through the forest understory. It feeds on insects, spiders, and other invertebrates found on the forest floor. Despite being cryptic in behavior, the Chucao Tapaculo is locally common and conspicuous by sound within its range, which spans roughly from the Lake District of central Chile south to Tierra del Fuego. The IUCN classifies it as Least Concern, reflecting stable populations within intact Valdivian forest. Deforestation and conversion of old-growth forest to pine and eucalyptus plantations are the primary threats to the species' preferred habitat. The Chucao Tapaculo is a flagship species for temperate South American forest conservation.
