ハクトウワシ

アメリカの国鳥であり保全の成功を象徴するハクトウワシは翼開長が最大2.4 mに達し、北米全域の水辺近くの森林や湿地に生息する。強力な空中捕食者兼腐肉食者で魚を主食とするが、水鳥や腐肉も捕食する。DDT汚染と狩猟によって1960年代にほぼ絶滅に瀕したが、農薬の使用禁止と絶滅危惧種法の施行により劇的に回復した。

Club-Spur Orchid

Platanthera clavellata, the small green wood orchid or club-spur orchid, is a terrestrial orchid in the family Orchidaceae native to eastern North America, from Newfoundland and Manitoba south to Florida and Texas. The species grows in a variety of moist to wet habitats including bogs, fens, wet meadows, seeps, swamps, and moist deciduous or coniferous forests. It typically produces a single large basal leaf and a slender flowering stem bearing small, greenish-white or pale yellow flowers arranged in a loose spike. Like other Platanthera orchids, it is pollinated by night-flying moths attracted to its faint fragrance. The club-shaped spur of the flower, which contains nectar, gives the species its common name. P. clavellata is not currently assessed by the IUCN (Not Evaluated), but is considered secure across much of its range in Canada and the eastern United States, though local populations may be threatened by wetland drainage, habitat conversion, and browsing by deer. The species depends on symbiotic mycorrhizal fungi in the soil for germination and early growth, as is typical for terrestrial orchids.
