クロモモワタアシハチドリ

クロモモフサアシハチドリ（Eriocnemis derbyi）は、オスの特徴的な黒いもも部が白い脚の羽毛飾りと対照をなすアンデスのふさ足ハチドリです。エクアドルとコロンビアの標高1,500〜3,500 mの湿潤山地林と林縁に生息します。オスは藍紫色の尾を持つ輝く緑色の羽毛を誇示します。農業のためにアンデスの雲霧林が開拓されるにつれて個体数が減少し、準絶滅危惧（NT）に分類されています。

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.
