ニュートンヒタキ

<em>Newtonia brunneicauda</em>, the common newtonia, is a small passerine bird in the family Vangidae, endemic to the island of Madagascar. This insectivorous bird typically inhabits humid and subhumid forests, forest edges, and secondary vegetation in the eastern and northern parts of Madagascar. <em>Newtonia brunneicauda</em> forages actively in the mid-storey and understorey, gleaning insects and other small invertebrates from foliage and branches. Its geographic range is largely restricted to Madagascar, though occurrence data in the source records lists Norway, which may reflect a sampling artifact rather than the species' actual distribution. The species is currently assessed as Least Concern by the IUCN, with populations considered relatively stable despite ongoing forest loss in Madagascar. Biological traits such as lifespan, body size, and diet remain poorly documented at a population level for this species. The common newtonia is a characteristic component of Madagascar's endemic forest bird community and is considered an indicator of relatively intact forest habitat. Its conservation is linked to the preservation of Madagascar's remaining tropical forests, which face significant pressure from slash-and-burn agriculture and timber extraction.
