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.

Orange-winged Parrot / Orange-winged Amazon

A medium-sized amazon parrot of South American tropical and secondary forests, orange-winged amazons have predominantly green plumage with distinctive orange wing patches visible in flight, blue and yellow on the head. Found from Colombia and Trinidad east to Venezuela, the Guianas, and south through Brazil and Bolivia. One of the most common and widespread amazons, living in large, noisy flocks and roosting communally. They are widely kept as pets throughout Latin America and internationally.
