Comoro Drongo

<em>Dicrurus fuscipennis</em>, the Comoro drongo, is a passerine bird in the family Dicruridae, endemic to the Comoro Islands in the western Indian Ocean, primarily found on the island of Grande Comore. The species inhabits humid montane forest and forest edge habitats, particularly in the interior upland areas of the island where native forest cover persists. Like other drongos, it is an active and aggressive insectivore that typically perches prominently on exposed branches before sallying out to catch flying insects, a foraging behavior known as aerial hawking. Biological traits such as precise average lifespan, body length, and body weight remain poorly documented in consolidated scientific literature for this restricted endemic species. The Comoro drongo is largely glossy black with a slightly forked tail, resembling other drongo species in the region. Its restricted range and dependence on intact native forest make it highly vulnerable to ongoing deforestation on Grande Comore, where forest clearance for agriculture and fuel continues to reduce available habitat. <em>Dicrurus fuscipennis</em> is assessed as Endangered by the IUCN, reflecting its small population size, restricted range, and accelerating habitat loss driven by human land use on the island.

Compact Thread-leaf Century Plant

<em>Agave microceps</em>, the compact thread-leaf century plant, is a perennial succulent in the family Asparagaceae native to Mexico, representing one of the smaller members of the ecologically and culturally significant agave genus. Agaves are iconic succulents of arid and semi-arid regions characterised by a rosette of thick, fibrous leaves typically edged with teeth and terminating in a sharp spine. <em>Agave microceps</em> typically forms compact, densely-leaved rosettes with notably narrow, thread-margined leaves, distinguishing it from larger agave species. It inhabits rocky slopes, dry grasslands, and scrublands in its native Mexican range, adapted to well-drained soils and periods of seasonal drought. Like all agaves, it is monocarpic, flowering once after many years of vegetative growth before dying, producing a tall flower spike that provides food resources for bats, hummingbirds, and insects. The species is classified as Least Concern by the IUCN, indicating a stable population without critical current threats, though many agave species face pressure from illegal collection for the horticultural trade and habitat conversion. Agaves play important roles in native ecosystems as food sources for specialist pollinators and as habitat elements on rocky hillsides. Biological traits including average lifespan in the wild, precise rosette dimensions, and population data remain poorly documented for this species compared to more commercially important agaves.
