Collared Myna

The Collared Myna, known scientifically as <em>Acridotheres albocinctus</em>, is a passerine bird belonging to the starling family Sturnidae. <em>Acridotheres albocinctus</em> is recognised by its contrasting plumage, which typically features a dark body with a distinct white collar or band — a feature reflected in both its common and scientific names. As a member of the myna genus Acridotheres, this species generally inhabits open woodland, grassland edges, and areas associated with human settlement, where it forages on the ground for invertebrates, fruits, and seeds. 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 Myna is currently assessed as Least Concern on the IUCN Red List, indicating that the global population is considered stable without significant conservation concerns at this time.
