Coastal Cisticola

Cisticola haematocephalus, the coastal cisticola or red-headed cisticola, is a small passerine bird in the family Cisticolidae distributed across sub-Saharan Africa, inhabiting rank coastal and lowland grassland, tall reed beds adjacent to water bodies, and scrubby vegetation along rivers and wetland margins. The genus Cisticola, with over 50 species, represents one of the most speciose avian genera in Africa and is characterized by small, brown-streaked warblers that are notoriously difficult to distinguish in the field and are often best identified by voice. Cisticola haematocephalus is recognized by the rufous-chestnut crown that gives it its common and scientific names, distinguishing it from the numerous plain-crowned cisticola species with which it often shares habitat. Males perform conspicuous aerial display songs during the breeding season from exposed grass stems or in fluttering display flights. The species is assessed as Least Concern by the IUCN, being widespread across coastal and riverine lowlands of east, west, and central Africa. It constructs a characteristic deep, oval woven grass nest anchored within tall grass stems, often partially concealed by living grass folded around the nest entrance.

Polar bear

지구상에서 가장 큰 육상 육식동물인 북극곰은 700kg을 넘을 수 있으며 캐나다에서 러시아까지 북극 해빙 전역에 분포한다. 고리 물범과 수염 물범을 사냥하기 위해 해빙에 의존하는 고도로 특수화된 해양 포유류이다. 광활한 거리를 헤엄쳐 다닐 수 있는 뛰어난 수영 실력을 가지고 있다. 취약종으로 등재되어 있으며, 기후 변화로 인한 급격한 북극 해빙 감소로 심각한 압력을 받고 있다.
