Habitat & Geographic Range

Cochabamba Akodont

Habitat

Typically found in diverse terrestrial and aquatic ecosystems.

Capuchino Arrocero de Java

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, tropical and subtropical grasslands and savannas, and flooded grasslands and savannas, among 6 distinct biome types spanning the Afrotropic and Indomalayan realms. Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Africa (Tanzania), Asia (Taiwan, Thailand, Vietnam), Europe (5 countries), North America (United States), Oceania and the Pacific (Australia), and South America (Colombia, Venezuela). Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

Cochabamba Akodont

The Cochabamba akodont (Akodon siberiae) is a small South American rodent endemic to the Cochabamba department of Bolivia. A member of the speciose genus Akodon — the so-called grass mice — this species inhabits humid montane grasslands and shrublands in the Andes, typically at elevations between 2,500 and 3,800 metres. Like other akodont rodents, it is primarily granivorous and insectivorous, foraging among dense grass tussocks and low vegetation for seeds, invertebrates, and plant material. The species is fossorial to a degree, constructing runways and shallow burrows beneath grass cover that provide shelter from predators including raptors and small carnivores. Akodon siberiae was described relatively recently from specimens collected in the Cochabamba region and remains poorly known; much of its ecology and reproductive biology has been inferred from better-studied congeners. Population size estimates are unavailable, though the IUCN classifies it as Near Threatened due to its restricted range and ongoing habitat conversion driven by agricultural expansion, livestock grazing, and burning of Andean grasslands. The species may have some tolerance for modified habitats but its dependence on intact puna and montane scrub makes it vulnerable to continued land-use change. Conservation measures such as protection of remnant native grassland within its limited range are considered important for its long-term persistence.

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.
