Colombian Speckled Tree-rat

<em>Pattonomys semivillosus</em>, the Colombian speckled tree-rat, is an arboreal rodent in the family Echimyidae distributed within Colombia. Members of the genus <em>Pattonomys</em> are associated with tropical forest canopy habitats, where their semi-arboreal lifestyle allows exploitation of fruiting trees and epiphytic vegetation. The speckled pelage characteristic of this species likely provides camouflage within dappled forest light. <em>Pattonomys semivillosus</em> is currently listed as Least Concern by the IUCN, reflecting a population not considered to be under immediate threat of significant decline. However, like many forest-dependent Neotropical rodents, this species may be sensitive to deforestation and habitat fragmentation, which reduce connectivity between forest patches and limit access to food resources and mates. The species is presumed to feed primarily on plant matter, including seeds, fruits, and bark. Its ecological role likely includes seed dispersal within its forest habitat. Biological traits of this species remain poorly documented in the scientific literature.

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.
