ニコバルハイタカ

The Nicobar Sparrowhawk (<em>Accipiter butleri</em>) is a small island raptor belonging to the family Accipitridae, encompassing hawks, eagles, and kites. Detailed plumage and behavioral descriptions of this species are limited in the available literature. The Nicobar Sparrowhawk is associated with forest habitats, consistent with its restricted range on the Nicobar Islands in the Indian Ocean, where tropical forest constitutes the primary landscape. This species is assessed as Vulnerable by the IUCN, reflecting concern over its small and geographically confined population; ongoing habitat degradation within its island range is a likely contributing pressure to its elevated conservation status. Dietary, nesting, and clutch size data for this species are not well documented in available sources. Song and call descriptions are similarly sparse. As a member of the genus <em>Accipiter</em>, the Nicobar Sparrowhawk is broadly expected to be a predatory species targeting small vertebrates within forest environments, though specific behavioral accounts are limited.
