Common Big-eared Bat

The common big-eared bat (<em>Micronycteris microtis</em>) is a small insectivorous bat belonging to the family Phyllostomidae, native to tropical and subtropical regions of South America. Its range includes Colombia and Venezuela, where it typically inhabits diverse terrestrial and aquatic environments including forests and riparian zones. It is classified as Least Concern on the IUCN Red List, indicating a relatively stable population. As its common name suggests, <em>Micronycteris microtis</em> is distinguished by notably large ears relative to its body size, which enhance its echolocation capabilities for detecting prey and navigating complex forest environments. The species is often associated with lowland and foothill forests, roosting in caves, hollow trees, and dense vegetation. It typically feeds on insects and may also consume small vertebrates or fruit on occasion. Biological traits of this species remain poorly documented in the scientific literature.

イヌワシ

世界で最も強力で広く分布する猛禽類の一つであるイヌワシは、翼開長が2.2mに達し、北半球全域の山岳地帯に生息する。卓越した空中ハンターで、滑空飛行と時速200km以上の急降下を利用してウサギ、ノウサギ、ジリス、時には子鹿やキツネを捕食する。多くの文化において数千年にわたる鷹狩り伝統の中心的存在であった。
