Collared Palm-Thrush

The Collared Palm Thrush, known scientifically as <em>Cichladusa arquata</em>, is a passerine bird belonging to the family Muscicapidae, the Old World flycatchers. <em>Cichladusa arquata</em> is a notable singer, often characterised by its melodic and varied song delivered from prominent perches. The species typically inhabits woodland, thicket, and savanna habitats, often in areas with scattered trees or dense shrubbery, including areas near human habitation. As the common name suggests, the species is often associated with palm groves and similar vegetation types. It is reported to occur in Norway according to available range data. Detailed biological traits including typical lifespan, body length, and weight are poorly documented for this species in available literature. The Collared Palm Thrush is currently assessed as Least Concern on the IUCN Red List, reflecting a stable global population without significant conservation concerns.
