コモロオリーブバト

<em>Columba pollenii</em>, the Comoro pigeon, is a medium-sized frugivorous pigeon in the family Columbidae, endemic to the Comoro Islands archipelago in the western Indian Ocean, where it occurs across the main islands including Grande Comore, Anjouan, Mohéli, and Mayotte. The species inhabits dense humid forest from lowland to montane elevations, depending on intact native forest for roosting, nesting, and foraging. It is a robust, predominantly dark-plumaged pigeon with metallic green and purple iridescence on the upperparts and a pale grey underside. Biological traits such as precise average lifespan, body length, and weight remain poorly documented in consolidated scientific literature. Like many island pigeons, <em>Columba pollenii</em> feeds primarily on fruits and seeds, contributing to forest regeneration through seed dispersal. The primary threats to the species are progressive deforestation for agriculture, charcoal production, and firewood collection, which continue to fragment and reduce native forest across the Comoro Islands. Hunting for food also poses a localized threat. <em>Columba pollenii</em> is assessed as Near Threatened by the IUCN, reflecting ongoing habitat degradation and population pressure across its restricted island range in the Comoros.

コンゴウインコ

南北アメリカ大陸で最も鮮やかな色彩を誇る鳥の一つであるコンゴウインコ(Ara macao)は、鮮烈な赤・黄・青の羽毛と翼開長最大1メートルの大きな翼を持ちます。メキシコからボリビアにかけての湿潤な低地森林に生息し、高い知性を持ち、最長75年の長寿で生涯を通じてつがいを形成します。種子の毒素を無害化するためにミネラル豊富な土を摂取するクレイ・リックまで長距離を移動します。軽度懸念に指定されていますが、生息地の喪失とペット取引により地域的に脅威にさらされています。
