Dunkelkusimanse

<em>Crossarchus obscurus</em>, commonly known as the common cusimanse or long-nosed cusimanse, is a small social mongoose in the family Herpestidae. This species is native to the rainforests and dense tropical forests of West and Central Africa. Common cusimanses are highly social animals that typically live in family groups and forage cooperatively on the forest floor, using their elongated, flexible snouts to root through leaf litter and soil in search of invertebrates, small vertebrates, and fallen fruits. They communicate through a variety of vocalizations and are known to mob and harass potential predators. The species is diurnal and terrestrial, sheltering in burrows or dense vegetation at night. Common cusimanses are assessed as Least Concern by the IUCN, with populations considered stable across their range. Biological traits such as lifespan and body measurements remain poorly documented in the scientific literature.

Javareisfink

One of the most popular cage birds in East Asia, Java sparrows are striking finches with grey plumage, a bold black head, distinctive white cheek patches, and a bright red bill. Native to Java and Bali in Indonesia, they have been introduced to many parts of Asia, Africa, and the Americas. They inhabit open grasslands, rice fields, and farmland, often becoming pests on rice crops. Listed as Vulnerable in their native range due to severe trapping pressure for the cage bird trade.
