Common Least Skipper

The Common Least Skipper (<em>Ancyloxypha numitor</em>) is a small butterfly in the family Hesperiidae, classified as Least Concern on the IUCN Red List. It is native to Canada and the United States, where it typically inhabits virtually all terrestrial and freshwater habitats within its range, showing a particular affinity for moist, grassy areas near water. The species is among the smallest skippers in North America, characterized by orange and brown wing coloration and a rapid, low-flying flight pattern close to vegetation. Adults typically nectar on small flowers while larvae feed on grasses, particularly those in wet meadows, marshes, stream margins, and disturbed grassy areas. The Common Least Skipper is frequently observed in wetland margins, wet prairies, and roadsides with rank grass growth. Its wide distribution across North America and habitat generalism across moist grassland and wetland types support its stable population and Least Concern conservation status. 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。
