American Bald Eagle

흰머리독수리(Haliaeetus leucocephalus)는 미국의 국조이자 미국 자연 보전 성공의 상징으로, 날개 폭이 최대 2.4미터에 달하며 북미 전역의 수변 삼림과 습지에 서식한다. 주로 물고기를 포식하는 강력한 공중 포식자이자 청소 동물로, DDT 오염과 남획으로 1960년대에 멸종 위기에 처했으나 농약 사용 금지와 멸종위기종보호법 시행 이후 극적으로 개체수가 회복되었다.

Coastal Brown

Cassionympha perissinottoi, the coastal brown, is a butterfly in the family Nymphalidae, subfamily Satyrinae, endemic to the coastal regions of South Africa. Satyrines, commonly called browns or ringlets, are typically medium-sized butterflies with cryptic brown and orange wing patterns that blend effectively with grass and dead vegetation in their grassland and woodland edge habitats. Cassionympha perissinottoi inhabits coastal grassland, dune thicket margins, and moist grassy areas along the eastern South African coast where suitable grass species, which serve as larval host plants, are available. The genus Cassionympha is endemic to Africa and comprises a small number of related species adapted to grassland and savanna habitats. Like many satyrid butterflies, the larvae feed on grasses and the adults feed on rotting fruit, dung, or take moisture from wet soil rather than flower nectar. The species is classified as Least Concern by the IUCN, though coastal grassland habitats in South Africa have been significantly reduced through urban development, plantation forestry with invasive pines and eucalypts, and coastal resort development along the KwaZulu-Natal shoreline.
