Common Fat-tailed Mouse Opossum

The Common Fat-tailed Mouse Opossum (<em>Thylamys pusillus</em>) is a small marsupial belonging to the genus Thylamys within the family Didelphidae. Like other members of its genus, this species typically stores fat in its tail, which becomes swollen during periods of food abundance and is metabolised during leaner times, a physiological adaptation that provides energy reserves. <em>Thylamys pusillus</em> is generally found in diverse terrestrial and aquatic ecosystems, often in dry woodlands, scrublands, and grassland habitats of South America. The species is assessed as Least Concern on the IUCN Red List, indicating it is not currently considered at risk of extinction. Detailed geographic range data are not available in the current record, but members of this genus are typically distributed across parts of Argentina, Bolivia, Paraguay, and Uruguay. Biological traits including average lifespan, body dimensions, and specific dietary composition remain poorly documented in the scientific literature, though Thylamys species are generally considered omnivorous, often consuming insects, small vertebrates, and plant material.

Солдатский амазон

A large, predominantly green amazon parrot with distinctive dark-scaled nape feathers and a patch of red on the wing, scaly-naped amazons inhabit humid montane forests of the northern and central Andes in Colombia, Venezuela, Ecuador, and Peru at elevations of 600–3,000 meters. Relatively little known compared to other amazons, they are found in pairs or small flocks feeding on seeds, fruit, and flowers in cloud forest. Listed as Least Concern.
