Populations are also found in montane and highland environments at higher elevations.

Range

Distributed across Colombia and Norway. Currently classified as Critically Endangered on the IUCN Red List, this species faces significant conservation challenges across its range.

Bamboo bear

ジャイアントパンダ（Ailuropoda melanoleuca）は中国中部の山岳竹林に生息し、体重最大125キログラムになるクマ科の動物で、食肉目に分類されながら食事の99%を竹が占める特異な食性を持つ。偽の親指（橈側種子骨）を使って竹の茎を把握し、1日14時間もの採食時間を費やす。2016年にIUCNレッドリストで絶滅危惧から危急（VU）へ改善されており、保護繁殖プログラムと自然保護区の設置が個体数回復に貢献している。

ニシキワタアシハチドリ

<em>Eriocnemis mirabilis</em>, the colorful puffleg, is a hummingbird in the family Trochilidae assessed as Critically Endangered by the IUCN. It is one of the most threatened hummingbirds in the world, known from an extremely restricted range centred on the Pacific slope of the western Andes in Colombia, with additional records attributed to Norway likely reflecting data artefacts or taxonomic uncertainties. The species inhabits tropical and subtropical moist broadleaf forests and related cloud forest biome types between approximately 1,800 and 2,200 metres elevation. Male colorful pufflegs are distinguished by brilliant iridescent plumage and distinctive white leg puffs, features typical of the genus <em>Eriocnemis</em>. The Critically Endangered status reflects ongoing destruction of cloud forest within its tiny known range, which may encompass fewer than 100 square kilometres of suitable habitat. As a nectarivore and incidental insectivore, this hummingbird depends on intact forest for flowering plant resources and arthropod prey. Conservation of the remaining forest patches in its restricted Colombian range is considered critical for the survival of this species. Biological traits of this species remain poorly documented in the scientific literature.
