Colombian spiny rat

<em>Proechimys canicollis</em>, the Colombian spiny rat, is a terrestrial rodent belonging to the diverse family Echimyidae, occurring in Colombia and Venezuela. Spiny rats of the genus <em>Proechimys</em> are among the most species-rich genera of Neotropical rodents, typically inhabiting lowland tropical and subtropical forests, forest edges, and secondary vegetation. The coarse, spine-like hairs that give this group its common name are thought to function as a deterrent against predators. <em>Proechimys canicollis</em> is assessed as Least Concern by the IUCN, suggesting stable populations across its range. This species likely feeds on seeds, fallen fruits, fungi, and invertebrates, and may play an important role as a seed predator and disperser in forest ecosystems. Research indicates that <em>Proechimys</em> species often achieve high local densities in undisturbed forest, making them important prey items for raptors, felids, and large snakes. Habitat loss in northern South America remains a background concern for long-term population stability. Biological traits of this species remain poorly documented in the scientific literature.

pardal-de-java

Um dos pássaros de gaiola mais populares no Leste Asiático, os pardais-de-java são tentilhões vistosos com plumagem cinza, cabeça preta marcante, manchas brancas características nas bochechas e bico vermelho brilhante. Nativos de Java e Bali, na Indonésia, foram introduzidos em muitas partes da Ásia, África e Américas. Habitam pastagens abertas, arrozais e terras agrícolas, frequentemente tornando-se pragas para as lavouras de arroz. Classificados como Vulneráveis em sua área de distribuição nativa devido à intensa pressão de captura para o comércio de pássaros em gaiola.
