The Australian crow is distinguished from the raven by its call
The Australian crow and raven are often tricky to tell apart due to their strikingly similar appearances. They are distinguished by their size, with ravens typically being larger than crows, and the colour of the down at the base of their feathers—brown for ravens and white for crows. However, these differences are subtle and hard to spot in the field. The most reliable way to tell them apart is by their calls.
The Australian Raven has a distinctive, high-pitched, and loud call that consists of three notes. Its call is described as rich and warbling. The Torresian Crow, on the other hand, has a "quacking quality" to its call, differing from the typical "cawing quality" of ravens. The Little Crow, found in arid regions of Australia, has a flat and nasal call that some describe as resembling an American accent.
The Torresian Crow, also called the Australian crow or Papuan crow, is a large bird native to the north and west of Australia and nearby islands in Indonesia and Papua New Guinea. It has a broad tail with a distinctive square-shaped tip and a dark grey bill about the same length as its head. Its plumage is glossy black on the back and dull black on the breast, with white feather bases on its head and neck. The eyes of adult birds are white with a fine blue eye-ring, while immature birds have duller black plumage and brown eyes.
The Australian Raven was first described in 1827 and is commonly sighted in major cities such as Sydney, Canberra, Perth, Adelaide, and Brisbane. It has jet-black feathers and is known for its intelligence, holding an important place in Indigenous lore.
