Habitat & Geographic Range

Capuchino Castaño

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, tropical and subtropical dry broadleaf forests, and tropical and subtropical coniferous forests spanning the Australasia and Indomalayan and Neotropic realms. Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Asia (Indonesia, Japan, United Arab Emirates), Europe (Norway, United Kingdom), North America (Haiti, Jamaica, United States), and South America (Colombia, Ecuador).

Collins' Squirrel Monkey

Habitat

Typically found in diverse terrestrial and aquatic ecosystems.

Capuchino Castaño

El capuchino ventricastaño es un pequeño pinzón estríldido robusto con plumaje marrón rojizo intenso, cabeza negra y vientre blanco, que habita praderas, arrozales y bordes de bosques abiertos desde India y Sri Lanka hacia el este a través del Sudeste Asiático hasta Filipinas y Taiwán. Muy gregario, forma grandes bandadas y a veces se considera una plaga agrícola menor en los cultivos de arroz. Ampliamente mantenido como ave de aviario en toda Asia, son relativamente fáciles de criar y mantener en cautiverio.

Collins' Squirrel Monkey

<em>Saimiri collinsi</em>, commonly known as Collins' Squirrel Monkey, is a primate species belonging to the genus <em>Saimiri</em> within the family Cebidae. Squirrel monkeys are small, highly social New World primates known for their agility in forest canopies and their complex group dynamics. This species is assessed as Least Concern by major conservation bodies, indicating that its populations are not currently considered at high risk of decline, though ongoing deforestation and habitat fragmentation in Amazonian regions may affect future population stability. Collins' Squirrel Monkey inhabits diverse terrestrial and aquatic-adjacent environments typical of tropical forest ecosystems in South America. Specific country-level distributional records are not detailed in current documentation. Dietary information specific to this species has not been recorded, though squirrel monkeys in general are omnivorous, consuming insects, small vertebrates, fruits, and other plant material. Biological traits of this species remain poorly documented in the scientific literature. Research into the taxonomy and ecology of <em>Saimiri collinsi</em> continues to refine understanding of squirrel monkey diversity.
