The
Crows, rooks and ravens are all part of the crow family, known as the corvids. The family also includes jackdaws, jays, magpies and choughs. These birds are intelligent, adaptable and able to exploit a wide range of food sources.
The Australian magpie, Cracticus tibicen, is conspicuously "pied", with black and white plumage reminiscent of a Eurasian magpie. It is a member of the family Artamidae and not a corvid.
Crows versus ravens
Australian species are more difficult to group this way, but generally if a corvid has white bases to the feathers on its neck and shoulders it's a crow (this can only be seen when the feathers are ruffled or the bird is moulting); and if they're totally black it's a raven.
The crow family (Corvids) are a family of birds that include crows, rooks, ravens, jackdaws, jays, magpies. The crow family is a group of medium to large birds usually black in appearance and are among the most intelligent and sociable birds in the UK congregating in large numbers and breeding in rookery's.
Mature magpies have dull red eyes, in contrast to the yellow eyes of currawongs and white eyes of Australian ravens and crows. The main difference between the subspecies lies in the "saddle" markings on the back below the nape. Black-backed subspecies have a black saddle and white nape.
There are many collective nouns for groups of magpies, but perhaps the most common are a mischief, conventicle, congregation, charm and tribe of magpies. Like crows, magpies are sometimes referred to as a murder, and like owls, they're sometimes referred to as a parliament.
Crows most often have an even caw, caw sound, while ravens have a deeper, throatier, croaking call. If you're able to observe a bird up close, you'll see that ravens have fluffier feathers around their head and especially at their throat. They also have thicker beaks than crows, with more of a curve to the end.
The five native species of Corvids (crows and ravens) in Australia are the Australian Raven, Little Raven, Little Crow, Forest Raven, and the Torresian Crow. They are all quite similar – ravens being perhaps slightly larger – and some can be difficult to tell apart in the field without close scrutiny.
Ravens differ from crows in appearance by their larger bill, tail shape, flight pattern and by their large size. Ravens are as big as Red-tailed Hawks, and crows are about the size of pigeons. The raven is all black, has a 3.5-4 ft wingspan and is around 24-27 inches from head to tail.
The Torresian crow (Corvus orru), also called the Australian crow or Papuan crow, is a passerine bird in the crow family native to the north and west of Australia and nearby islands in Indonesia and Papua New Guinea. The species has a black plumage, beak and mouth with white irises.
Magpies can also be taught to speak. They hide food and can relocate hidden food with incredible accuracy." With regard to their intelligence, magpies are very much like fellow corvids – jays, rooks, ravens and crows, says Walt Koenig, a senior scientist with the Cornell Lab of Ornithology.
Upto the 16th century they were just called pie but then the mag was added. Very often the jay is used for magpies around the world.
The true currawongs are a little larger than the Australian magpie, smaller than the ravens (except possibly the little raven, which is only slightly larger on average), but broadly similar in appearance.
No, crows and Magpies cannot mate. They belong to the same family but not to the same breed. Also, crows and magpies fight aggressively with each other and are not friendly at all.
The Australian raven can be distinguished from the two species of crow occurring in Australia by the grey base of the feathers, which is white in the latter species. The demarcation between pale and black regions on the feather is gradual in the ravens and sharply delineated in the crows.
What is the Term for a Group of Ravens? A group of ravens is called an unkindness. You can also refer to them as a rave, conspiracy, treachery, and flock.
Ravens aren't crows
There are crows in South Australia, but you'll generally only find them north of Port Augusta. So how can you tell them apart? Australian ravens – one of the most commonly spotted species in Adelaide – are bigger than crows and have hackles on their backs and a ruff of feathers on their neck.
A flock of crows is called a murder. A flock of ravens is called an unkindness. A flock of rooks is called a building, clamor, or parliament.
Crows in my neighborhood communicate with numbers: Two caws = “Where are you?” (I will often hear a distant reply of two caws, as in, “I'm over here.”) Three caws = “Danger!” (They'll do it whenever they see a dog or a person they don't know.)
Fast Facts. There are three species of raven in Australia, and three crows. Ravens are generally bigger than crows, but other differences - e.g. range, calls - are more reliable for identifying which species is which.
