Habitat & Geographic Range
Cinereous Bunting
Typically found in various aerial, terrestrial, and aquatic environments.
Distributed across Denmark, Norway, and Sweden.
Polar bear
Found across multiple habitat types including temperate broadleaf and mixed forests, temperate coniferous forests, and boreal forests and taiga, among 4 distinct biome types within the Palearctic biogeographic realm. Populations are also found in montane and highland environments at higher elevations.
Found in Norway. Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.
Cinereous Bunting
The cinereous bunting (Emberiza cineracea) is a small passerine bird in the family Emberizidae, with a breeding range centered on Turkey, the Greek Aegean islands, and parts of the eastern Mediterranean and Middle East. It breeds primarily on arid, rocky hillsides and sparse scrub at low to moderate elevations, and winters in the Arabian Peninsula, northeastern Africa, and the Middle East. The male is a distinctive pale gray-yellow bird with a streaked brown back and yellow-tinged head, while females are more streaked and less colorful. The species favors dry, open habitats with sparse vegetation, often nesting on the ground or in low scrub. The cinereous bunting is classified as Not Evaluated by the IUCN in some assessments, though it has also been assessed as Least Concern in others, reflecting a small to moderate global population concentrated in the eastern Mediterranean and Turkey. It is entirely absent from Norway; any such database record is an artifact of data entry error. Like other buntings, it feeds primarily on seeds outside the breeding season and takes invertebrates during nesting. Habitat loss in its breeding range, particularly degradation of traditional dry-land farming and grazing landscapes in Turkey and Greece, represents the primary conservation concern.
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.
