Family Crows and Jays (Corvidae)

Least Concern

Forest Raven (Corvus tasmanicus)


French: Corbeau de Tasmanie German: Tasmankrähe Spanish: Cuervo de Tasmania

Corvus marianae tasmanicus


, 1912,



Formerly considered a race of C. coronoides; one genetic analysis#R suggests the two may indeed be conspecific. Race boreus (sometimes referred to erroneously as novaanglica) has been treated as a full species#R, though without supporting evidence; near-identical vocalizations of the two taxa indicate that current treatment is appropriate, and this is corroborated by genetic data#R. Two subspecies recognized.
