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.

Comoro Rousette

<em>Rousettus obliviosus</em>, the Comoro rousette, is a fruit bat in the family Pteropodidae endemic to the Comoros archipelago in the Indian Ocean, primarily recorded from Anjouan and Mohéli islands. As an Old World fruit bat, it plays an important ecological role in pollination and seed dispersal across the island's native forests. The species inhabits tropical moist lowland and montane forests, roosting in caves and dense vegetation. Its range is severely restricted by the small land area of the Comoros, making it inherently vulnerable to habitat loss. Deforestation driven by agricultural expansion and charcoal production has significantly reduced available forest cover on the islands. The IUCN classifies the Comoro rousette as Vulnerable, reflecting ongoing population pressures and limited geographic distribution. It is presumed to feed on fruits, nectar, and pollen typical of Old World fruit bats, though detailed dietary studies are limited. Biological traits including precise body measurements and lifespan data remain poorly documented in the scientific literature. Conservation efforts on the Comoros islands face challenges due to limited resources, though the species benefits from some protection within national parks and forest reserves. Its survival depends on the preservation of intact native forest habitat across the archipelago.

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.
