Autillo de Marshall

The cloud forest screech-owl (Megascops marshalli) is a small owl in the family Strigidae endemic to the eastern slopes of the Andes in Peru and Bolivia, inhabiting cloud forest and humid montane woodland between approximately 900 and 2,200 meters elevation. Described scientifically in 1981, it belongs to the diverse Megascops screech-owl assemblage of the Americas. The species has brown, streaked cryptic plumage and small ear tufts typical of screech-owls, with a characteristic song used for territory advertisement in cloud forest habitats. It is nocturnal and insectivorous, feeding on large insects, small lizards, and other invertebrates caught in the forest understory. The cloud forest screech-owl has a restricted range on the humid eastern Andean slopes, where increasing deforestation for agriculture and coca cultivation reduces suitable habitat. Its population status is considered Least Concern given the continuing extent of Andean cloud forest in its range, though forest clearance on the eastern Andean slopes remains a long-term threat to this and many other narrowly endemic cloud forest bird species.

Delfín tonina

La especie de delfín más estudiada y reconocida, los delfines mulares habitan océanos cálidos y templados de todo el mundo, desde las aguas costeras poco profundas hasta el mar abierto. Altamente inteligentes con grandes cerebros en relación con el tamaño corporal, demuestran autoreconocimiento, comunicación compleja y aprendizaje social. Viven en sociedades fluidas de fisión-fusión y cooperan para arrear peces. Una especie indicadora clave de la salud del ecosistema marino.
