중형 마코앵무로 멕시코 남부에서 볼리비아와 브라질에 이르는 중앙 및 남아메리카 열대 우림에 서식하며, 밤색 이마, 붉은 어깨 반점, 청색 날개 깃털을 가진 주로 녹색 깃털이 특징이다. 진정한 마코앵무 중 가장 작은 종으로, 산림 가장자리, 사바나, 2차 삼림에 서식하며 종종 농작물을 습격해 지역 농민들에게 인기가 없다. 인기 있는 사육용 새이지만, 야생 개체군은 포획과 삼림 벌채로 인한 압박을 받고 있다.

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.
