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.

Common Flicker

<em>Colaptes auratus</em> is a large woodpecker in the family Picidae, order Piciformes, commonly known as the northern flicker. Unlike most woodpeckers, this species frequently forages on the ground, using its long tongue to extract ants and beetle larvae from the soil. <em>Colaptes auratus</em> is documented in Europe and the United States, where it inhabits open woodlands, forest edges, suburban areas, and parks with mature trees suitable for nesting. The species is notably adaptable in its habitat use and is one of the most widespread woodpeckers in North America. It is easily recognized by its brownish-barred plumage, spotted underparts, and a bold white rump patch visible in flight. Two main subspecies groups are recognized — the yellow-shafted form in the east and the red-shafted form in the west — which interbreed extensively where their ranges meet. Flickers are cavity nesters, excavating holes in dead or dying trees. Biological traits of this species remain poorly documented in the scientific literature.
