Delfín de Commerson

<em>Cephalorhynchus commersonii</em>, commonly known as Commerson's Dolphin, is a small cetacean in the family Delphinidae. This species is classified as Least Concern on the IUCN Red List and is notable for its striking black-and-white coloration, which makes it one of the most visually distinctive dolphin species. Commerson's Dolphins typically inhabit coastal and nearshore marine environments of the Southern Hemisphere, particularly around the Falkland Islands, the southern tip of South America, and a geographically isolated population near the Kerguelen Islands in the Indian Ocean. These dolphins are highly social animals, often observed in small groups engaging in acrobatic behaviors near the surface. They typically feed on fish, squid, and crustaceans, often hunting cooperatively in shallow waters and kelp beds. Their average lifespan is approximately 18 years, and they are known for their fast, energetic swimming. Commerson's Dolphins are sometimes caught as bycatch in fishing nets, posing a localized conservation concern despite their overall Least Concern status.

Capuchino Arrocero de Java

Uno de los pájaros enjaulados más populares en Asia Oriental, los gorriones de Java son pinzones llamativos con plumaje gris, una audaz cabeza negra, manchas blancas características en las mejillas y un brillante pico rojo. Originarios de Java y Bali en Indonesia, han sido introducidos en muchas partes de Asia, África y las Américas. Habitan pastizales abiertos, arrozales y tierras de cultivo, donde suelen convertirse en plagas para los cultivos de arroz. Clasificados como Vulnerables en su área de distribución nativa debido a la fuerte presión de captura para el comercio de aves enjauladas.
