gavião-caranguejeiro-negro

The common black hawk (<em>Buteogallus anthracinus</em>) is a medium-sized raptor of the family Accipitridae, classified as Least Concern on the IUCN Red List. It inhabits aerial, terrestrial, and aquatic environments across its range, which includes Colombia, Ecuador, Venezuela, and, notably, Norway, suggesting occasional vagrant or introduced occurrences outside its core Neotropical distribution. <em>Buteogallus anthracinus</em> is typically associated with riparian forests, mangroves, and wetland edges, where it hunts crabs, fish, frogs, and other aquatic prey along stream banks and shorelines. The bird is predominantly black with a broad white tail band, making it distinctive in the field. It often perches conspicuously on exposed branches near water, scanning for prey below. The species typically nests in tall trees near water, constructing large stick nests used across multiple breeding seasons. Biological traits of this species remain poorly documented in the scientific literature.

Comoro Rousette

<em>Rousettus obliviosus</em>, the Comoro rousette, is a fruit bat in the family Pteropodidae endemic to the Comoros archipelago in the Indian Ocean, primarily recorded from Anjouan and Mohéli islands. As an Old World fruit bat, it plays an important ecological role in pollination and seed dispersal across the island's native forests. The species inhabits tropical moist lowland and montane forests, roosting in caves and dense vegetation. Its range is severely restricted by the small land area of the Comoros, making it inherently vulnerable to habitat loss. Deforestation driven by agricultural expansion and charcoal production has significantly reduced available forest cover on the islands. The IUCN classifies the Comoro rousette as Vulnerable, reflecting ongoing population pressures and limited geographic distribution. It is presumed to feed on fruits, nectar, and pollen typical of Old World fruit bats, though detailed dietary studies are limited. Biological traits including precise body measurements and lifespan data remain poorly documented in the scientific literature. Conservation efforts on the Comoros islands face challenges due to limited resources, though the species benefits from some protection within national parks and forest reserves. Its survival depends on the preservation of intact native forest habitat across the archipelago.
