Cuclillo de Isla del Coco

The Cocos Cuckoo (Coccyzus ferrugineus) is a medium-sized bird in the family Cuculidae, endemic to Cocos Island, a remote volcanic island in the eastern Pacific Ocean approximately 550 kilometres southwest of the Costa Rican coast. This island-restricted species is closely related to mainland cuckoos in the genus Coccyzus and represents a classic example of insular endemism. Adults display rufous-brown upperparts, a pale buffy underside, and a moderately long tail with white tail-tip spots on the dark outer feathers. The species inhabits the dense tropical forest that covers much of Cocos Island, foraging in the mid-canopy for caterpillars, insects, and small lizards. As with other cuckoos, Cocos Cuckoos are often cryptic and detected more readily by their calls than by direct observation. The species is classified as Vulnerable by the IUCN due to its severely restricted range on a single island of approximately 24 square kilometres, making any localised disturbance potentially significant. Threats include introduced mammals—particularly feral pigs and cats—that degrade forest structure and prey on nesting birds. Cocos Island is a protected national park and UNESCO World Heritage Site, offering some measure of safeguard, but continued monitoring of invasive species management is essential. Population estimates remain uncertain, but the bird appears to be a common resident within the island's forested interior.

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.
