Named after their resemblance to the Eurasian magpie, to which they are not actually closely related, Australian magpies are a protected native species, and to some, a beloved national icon.
Their beautiful warble is a quintessential Australian sound and, as predators of many pests, they are vital to the country's ecosystems.
They are also incredibly intelligent - so smart they have even been caught helping each other unscrew scientific tracking devices - and they have also been known to strike up long-term, meaningful friendships with humans.
One Sydney family even credits a rescued chick named Penguin with helping them recover from a catastrophic accident, a heart-warming tale which grabbed global headlines and has since been turned into a best-selling book and a film.
"They're silent killers… I'll just see this shadow over my head getting bigger and bigger and bigger."
"I have asthma and I would be sprinting, having an asthma attack on the train, just to get away from this magpie.
"I don't know why it hated me, but it did… I never did anything wrong, I swear!"
Why do magpies swoop?
Australians are well accustomed to swooping birds - there's plovers, noisy miners and even the kookaburra.
But magpies are considered the ultimate "swoopy boy" and few people are without a story.
Only a very small portion of male magpies engage in the practice though, and when they do, it's to protect their nests during breeding season, from August to November.
Experts say they do not swoop unprovoked.
But they also say magpies can interpret simple gestures like running through their territory as a slight, and not only can they recognise individual faces - they tend to hold a grudge.
"Let's say you've shown some kind of response by waving your arms or trying to hit the bird away from you," says animal behaviourist and Emiritus Professor Gisela Kaplan, who literally wrote the book on magpies.
"That act is a declaration of open war. A magpie interprets that as a sign of aggression and will then always swoop that person from then on, every year.
"[And] somebody of a similar build, a similar height and hair colour may get mistaken in their fury, or anxiety."
They have also been known to pre-emptively target cyclists and children because they don't trust them - cyclists because "magpies think as little of covered faces as people in banks do of [those] in balaclavas", and children because they are "less reasonable and may be a greater risk", Prof Kaplan says.
For most people who are hit by magpies, it is a cut or scratch.
But they have been known to blind some - in the last fortnight a cyclist made the news after revealing a serial dive-bomber had left him needing major surgery and a prosthetic eye lens.
"This bird turned around and went straight for the eye, did a backflip and hit me right in the eye again," Christiaan Nyssen said.
And in 2021, a baby was killed when her mother fell during her efforts to dodge a magpie - a case that horrified the country.
Two years earlier an elderly man died of head injuries after crashing his bicycle while fleeing an attacking magpie, and in 2010 a 12-year-old boy was hit and killed by a car in similar circumstances.
Serious injuries and deaths are rare though. What is far more common is human aggression towards the birds.

In May a Victorian man was fined after killing four magpies and injuring another two so seriously they were euthanised. And almost every year, wildlife officers report finding birds pierced with arrows, shot with guns, set on fire, shackled with chains, poisoned, or mutilated.
How to make peace
Animal behaviourists say the magpie is misunderstood, and there's no need for them to be harmed. It is our fear and response to them that is dangerous.
Yes, there are a very small number of "rogue" birds which have become aggressive - radicalised by interactions with humans - says Prof Kaplan. They should be "dealt with firmly".
But the vast majority of magpies are reasonable creatures, she insists.
The best thing to do is avoid them. Authorities often erect signs, warning of magpies in the area, and some states have even launched apps designed to track sightings of nests.
If you are swooped, don't run, or fight back, experts advise. If you're on a bike, get off it. Stay calm and walk quickly through the area. Shelter under an umbrella or hold your backpack over your head.
The use of protective gear is also encouraged, like sunglasses and magpie hats.

Traditionally, they have been a plastic ice-cream container - with eyes drawn or stuck on - or a helmet laced with zip ties. In recent years though, they've become more elaborate. For example, contraptions rigged up with party poppers or adorned with a fake magpie.
