Common Coral Tree

<em>Erythrina lysistemon</em>, commonly known as the common coral tree or lucky bean tree, is a medium to large deciduous tree in the family Fabaceae. Native to southern Africa, it is particularly characteristic of South Africa's woodlands, bushveld, and coastal forests, and has also been recorded in Portugal as an introduced species. The common coral tree is renowned for its spectacular scarlet tubular flowers, which appear before the leaves in late winter and spring and attract nectar-feeding birds, particularly sunbirds. Its seeds are bright red with a black spot and have been used in traditional jewelry and decoration. The tree produces compound leaves with three broadly ovate leaflets and is armed with sharp curved spines on its trunk and branches. It is assessed as Least Concern by the IUCN. Biological traits of this species remain poorly documented in the scientific literature.

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.
