Amazone à front bleu

One of the most popular pet parrots in the world after the budgerigar and African grey, blue-fronted amazons are recognized by their bright yellow face with blue forehead and red-orange shoulder patches. Native to central South America in Brazil, Bolivia, Paraguay, and Argentina, they inhabit forest, woodland, and palm groves. Highly intelligent with strong mimicry and speech abilities, they have been kept as pets since the 1700s. Wild populations face pressure from trapping.

Petit opossum-souris

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.
