Australian Magpies are strongly territorial and defend their territories both from other magpies as well as potential predators. Unfortunately, some individual magpies perceive humans as a potential threat and accordingly, swoop down with a fast warning flight, occasionally making contact.
The ones that do are just using their body language – beak clapping, whooshing above your head and screeching – to warn other birds, animals and humans to keep away from their eggs or newly-hatched chicks. Magpies usually breed between August and October.
“Only 10 per cent of the male magpies actually swoop people and the research suggests it is actually a learned behaviour,” Dooley says. “These birds might have had a bad experience with humans in the past, and they remember that and swoop when humans come near their nest.”
"We know that magpies remember and recognise human faces and they will remember them for years," Dr Kaplan told ABC Radio Melbourne's Sami Shah and Jacinta Parsons.
Don't fight back if a magpie swoops. Throwing sticks and stones or yelling at a magpie are likely to make it more aggressive next time anyone enters the defence zone around their nest. Never approach a young magpie.
And since magpies can live between 25 and 30 years and are territorial, they can develop lifelong friendships with humans. This bond can extend to trusting certain people around their offspring.
Magpies love:
Open woodlands with tall trees but no understory. Big, old trees which give them somewhere safe to build their nests and sleep at night.
Myth 2: Magpies target certain colours
None of the research about magpies to date has found that magpies target specific colours, such as orange, yellow or purple. Instead, it is widely believed that they swoop purely to protect their young.
Use Decoys And Reflective Objects
There's one thing magpies are really scared of – flashing lights. You can keep magpies at bay by placing any reflective object in your yard.
Make eye contact with the magpie.
Magpies usually swoop from behind, so they are much less likely to swoop if they are being watched directly. As you walk away, try to maintain eye contact by looking over your shoulder as often as you can.
Magpies can swoop from July through to December (usually for about 8 weeks) during the spring while they build nests, lay and protect eggs and raise nestling and fledgling birds. Not all magpies will swoop but some will as a natural instinct to protect their territory (area around their nest) and their young.
Magpies swoop in spring
Peak breeding season for Australian magpies is August through to November, which is normally when the swooping begins. During this time, they will defend their nests and chicks, but also defend their surrounding territory.
When is magpie swooping season? September is peak magpie swooping season. However, the birds typically nest from July to December and have been known to swoop then too. Magpies tend to swoop for about six weeks as their mate incubates eggs and while the chicks are very young.
While magpies might be better known for their aggression, they also display extremely submissive behaviours. 'Young birds and subordinates will bow down and shake their tail feathers when a dominant male or female is near,' Connelly explains.
Natural predators of magpies include various species of monitor lizard and the barking owl. Birds are often killed on roads or electrocuted by powerlines, or poisoned after killing and eating house sparrows or mice, rats or rabbits targeted with baiting.
Magpies have several predators including domestic cats, dogs, foxes, and owls. Also, they can have eggs as well as chicks stolen out of their nest by raccoons, hawks, weasels, and mink.
The months following fledging are a dangerous time for young magpies, with a high percentage failing to make it through the first year. If the young birds survive to breed, their average life expectancy is around three years. Some live much longer than this, with the oldest recorded being more than 21 years old.
What Is A Group of Magpies Called? There are many collective nouns for magpies, but perhaps the most common names for a group of magpies are a conventicle, gulp, mischief, tidings or tribe of magpies[i].
Is It Okay to Feed Magpies? It's best not to feed magpies. Apart from giving them wrong foods that may damage their health, magpies can easily become territorial birds around people and other birds. They will view people they have never seen before as intruders.
Males are typically larger than females and have longer beaks, while females are usually smaller with shorter beaks. The physical traits that allow for identification of the gender of adult White-backed magpies are located on their napes and mantles which are key areas to observe in the White-backed magpie.
The diet of a magpie
Their main diet in summer is grassland invertebrates, such as beetles, flies, caterpillars, spiders, worms and leatherjackets. In winter, they eat more plant material, such as wild fruits, berries and grains, with household scraps and food scavenged from bird tables or chicken runs, pet foods etc.
Raw meat, cheese and bread off the menu
Brisbane bird and exotic animal vet Deborah Monks said raw meat and mince, although popular, did the most damage to magpie health. "I wouldn't recommend raw mince on its own because it doesn't have enough calcium in it," she said.
The common magpie is one of the most intelligent birds—and one of the most intelligent animals to exist. Their brain-to-body-mass ratio is outmatched only by that of humans and equals that of aquatic mammals and great apes.
