Common Birch

The common birch (<em>Betula pendula</em>), also known as the silver birch, is a deciduous tree with a broad distribution spanning Africa, Europe, North America, Oceania, and South America. Countries in its range include South Africa, several European nations, Canada, the United States, Australia, New Zealand, and Argentina. It is classified as Least Concern on the IUCN Red List. <em>Betula pendula</em> typically grows in a wide variety of terrestrial habitats from tropical lowlands to temperate montane forests, demonstrating considerable ecological versatility. The tree is easily recognized by its slender form, pendulous branches, and distinctive white or silvery bark that peels in papery strips. It is often a pioneer species, rapidly colonizing disturbed and open ground. Common birch plays an important ecological role as a habitat and food source for numerous insects, birds, and fungi. Its wood is valued for furniture, flooring, and plywood production. Biological traits of this species remain poorly documented in the scientific literature.

アオフタオハチドリ

ナガオシルフハチドリ(Aglaiocercus kingii)は最も鮮やかに装飾されたハチドリの一つで、雄は虹色の緑色羽毛と22cmに達するリボン状に長く伸びた外側尾羽を持ち、これは体長の3倍を超える。コロンビアとベネズエラのアンデス雲霧林の標高1,400〜2,800mに生息し、雄は雌を引き付けるために精巧な誇示飛行を行う。その華麗な尾羽は、雌の選好による性的選択の古典的な例である。
