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.

ミミグロハチドリ

ハチドリの中で単色または虹色の羽毛が主流な中、珍しく班点や斑点のある下面を持つ中型のハチドリで、コロンビアとベネズエラからボリビア南部まで標高900〜3,000メートルのアンデスの雲霧林と林縁に生息する。班点のある下面パターンは、苔に覆われた樹皮に止まる際に卓越した迷彩効果を提供する。蜜と小型節足動物を採食し、アンデスの着生植物の重要な花粉媒介者として機能する。
