Buckelwal

혹등고래는 대형 고래 중 가장 활발한 곡예를 선보이는 종으로, 번식기에 수컷이 부르는 복잡하고 신비로운 노래로 유명합니다. 일부는 몇 시간씩 지속되며 시간이 지남에 따라 진화합니다. 체장 16미터, 체중 30톤에 달하며 포유류 중 가장 긴 이주를 수행합니다. 모든 대양에서 발견되며 크릴과 작은 물고기를 협동 거품그물 먹이 방식으로 포식합니다. 과거 포경으로 크게 감소했던 개체군이 대부분 회복되었습니다.

Colombian Screech-Owl

<em>Megascops colombianus</em>, commonly known as the Colombian screech-owl, is a small nocturnal raptor native to the Andean foothills of Colombia and Ecuador. This species inhabits tropical and subtropical montane forests, where it occupies a range of elevations typically between 1,000 and 2,000 metres above sea level. The Colombian screech-owl is assessed as Near Threatened by the IUCN, reflecting ongoing habitat loss driven by agricultural expansion and deforestation within its restricted range. Like other members of the genus <em>Megascops</em>, this owl is presumed to be an insectivore and opportunistic predator of small vertebrates, hunting under cover of darkness using acute hearing and silent flight. Its cryptic plumage provides effective camouflage against tree bark, making individuals difficult to detect. The species is poorly known, with limited published data on its breeding biology, population size, and precise ecological requirements. Research indicates that ongoing forest fragmentation in the Colombian Andes represents the primary threat to long-term population viability. Biological traits of this species remain poorly documented in the scientific literature.
