Comoro Pigeon

<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.
