The Australian Magpie (Cracticus tibicen) is a medium-sized black and white passerine bird native to Australia and southern New Guinea. A member of the Artamidae, it is closely related to the butcherbirds. At one stage, the Australian Magpie was considered to be three separate species, although zones of hybridisation between forms reinforced the idea of a single species with several subspecies, nine of which are now recognised. The adult Australian Magpie is a fairly robust bird ranging from 37–43 cm (14.5–17 in) in length, with distinctive black and white plumage, red eyes and a solid wedge-shaped bluish-white and black bill. The male and female are similar in appearance, and can be distinguished by differences in back markings. With its long legs, the Australian Magpie walks rather than waddles or hops and spends much time on the ground. This adaptation has led to some authorities maintaining it in its own genus Gymnorhina. Described as one of Australia's most accomplished songbirds, the Australian Magpie has an array of complex vocalisations.
The Australian Magpie is omnivorous, with the bulk of its varied diet made up of invertebrates. It is generally sedentary and territorial throughout its range. Common and widespread, it has adapted well to human habitation and is a familiar bird of parks, gardens and farmland in Australia and New Guinea. Magpies were introduced into New Zealand in the 1860s and are proving to be a pest by displacing native birds. Introductions also occurred in the Solomon Islands and Fiji, where these birds have not become invasive.
Spring in Australia is magpie season, when a small minority of breeding magpies (almost always males) around the country become aggressive and swoop and attack those who approach their nests, especially bike riders. This species is commonly fed by households around the country and is the mascot of several famous Australian sporting teams.
One of Australia's most highly-regarded songbirds, the Australian Magpie has a wide variety of calls, many of which are complex. Pitch may vary over up to four octaves, and the bird can mimic over 35 species of native and introduced bird species, as well as dogs and horses. Its complex, musical, warbling call is one of the most familiar Australian bird sounds. In Denis Glover's poem The Magpies, the mature magpie's call is described as quardle oodle ardle wardle doodle, one of the most famous lines in New Zealand poetry, and in the children's book Waddle Giggle Gargle by Pamela Allen.
When alone, a magpie may make a quiet musical warbling; these complex melodious warbles or subsongs are pitched at 2–4 KHz and do not carry for long distances. These songs have been recorded up to 70 minutes in duration and are more frequent after the end of the breeding season. Pairs of magpies often take up a loud musical calling known as carolling to advertise or defend their territory; one bird initiates the call with the second (and sometimes more) joining in. Often preceded by warbling, carolling is pitched between 6–8 kHz and has 4–5 elements with slurring indistinct noise in between. Birds will adopt a specific posture by tilting their heads back, expanding their chests, and moving their wings backwards. A group of magpies will sing a short repetitive version of carolling just before dawn (dawn song), and at twilight after sundown (dusk song), in winter and spring.
Magpies outside of breeding season adapt very well to humans as a food source, and will often land and sit next to someone doing their gardening. If a worm is unearthed, they will swoop in and grab the worm as wait for the next one.
Often you could have 20 or 30 of them standing around if you are digging, waiting to grab worms.

Your Magpies are much different than ours. Much more colorful to be sure. If white can be considered a color, eh?
I have a video of some Red-Winged Blackbirds that I'll post as soon as I'm sure esnips is working correctly. I can email it to you also.
There's a program available called Pando and it's free. I could send you whole folders of my pictures, videos, etc., if you download it at www.pando.com , I believe. It allows you to bypass your ISPs limitations on file size and it works perfectly.
Let me know if you download it. I can bury you in pictures!! lol
