Comoro Blue-Pigeon

<em>Alectroenas sganzini</em>, the Comoro blue pigeon, is a medium-sized frugivorous pigeon in the family Columbidae, endemic to the Comoro Islands archipelago in the western Indian Ocean, with occasional records from Aldabra Atoll in the Seychelles. The species inhabits dense evergreen humid forest, forest edges, and heavily wooded areas, typically from sea level to higher elevations on the main islands. Like other members of the genus <em>Alectroenas</em>, it displays striking plumage featuring a bright blue-grey body, a bare red facial patch around the eye, and a short rounded tail. Biological traits such as precise average lifespan, body length, and weight remain poorly documented in consolidated scientific literature, though it is a medium-sized pigeon typical of its genus. The Comoro blue pigeon feeds primarily on fruits, figs, and other forest products, contributing to seed dispersal in native forests. Threats include ongoing habitat loss through forest clearance for agriculture and charcoal production, along with hunting pressure. <em>Alectroenas sganzini</em> is assessed as Near Threatened by the IUCN, reflecting population declines driven by deforestation and exploitation across its restricted island range in the Comoros.
