Only a few magpies see people as a threat. Most will not swoop you. Magpies see cats, dogs and other magpies as intruders - it's not just people they swoop. Harassment by humans causes some magpies to start swooping.
Magpies are very territorial and protective of their nests. During the nesting season, they will mob and attack humans, pets, and other birds near their nests.
It's not just humans that Magpies see as a threat to their young. It's for this reason that dogs and cats can also attract their wrath. To protect your pets as much as possible: Make sure dogs are on-leash when walking through a Magpie's territory.
Only a small proportion of magpies swoop on people and these often have a preference for a few individuals that the birds recognise or certain types of 'targets' like pedestrians and cyclists. A magpie will only defend its nest within a 'defence zone'.
“It's the birds responding to things they perceive as threats. That includes humans, dogs, cats, snakes and anything else the magpie decides is a threat to its chicks.”
Magpies swoop in spring
During this time, they will defend their nests and chicks, but also defend their surrounding territory. Male adults are using their body language – beak clapping, whooshing above your head and screeching – to warn you to keep away from their eggs or newly-hatched chicks.
Overview. 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 don't seem to notice the eyes, and may attack from the side instead, and don't seem overly bothered by the appearance of cable ties.
While it's no doubt cold comfort for people who have a territorial magpie on their block, swoopers are actually quite rare. The Australian Academy of Science says only one in 20 male magpies will swoop to protect their incubating mates, and eight out of ten people in magpie territory will never get swooped.
Every year from early August to late October, the Australian magpie loses its tiny feathered gourd and starts indiscriminately dive-bombing anything that comes within 50 to 100 metres (164 to 328 feet) of its nest, as seen in a video that went viral this week.
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.
Like dogs, magpies seem to sense fear and will capitalise on it by pressing an attack. In a strike attack, a magpie swoops, hovers momentarily and then strikes. The fluttering of wings as the bird hovers is usually sufficient warning for adults and older children to duck their heads and avoid the attack.
Although magpies will peck around in the soil looking for insects, the main garden damage is done to the lawn where they create holes while looking for grubs, such as leatherjackets and chafer grubs. That being said, magpies are a useful control for these two root-eating plant pests.
Our canine friends are not nearly as clever as chimpanzees or dolphins. They rank in a similar way to cats, goats and pigs. And depressingly, in some ways, they aren't as smart as birds like pigeons and magpies.
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. Hunting and eating insects. Mimicking other birds' calls, car alarms, dogs barking, phones ringing and even human voices.
Statistics compiled by the community website Magpie Alert suggest that most swooping takes place between August and October. "When the fledglings are out of the nest, the nest defence activity decreases," Ratnayake says.
Magpies normally sleep during darkness, but if you're in an area with a lot of artificial light, they have been known to stay awake due to that light. It's possible that you got swooped on by a magpie if you're in a busy part of a city, but very unlikely if you're out in a remote area.
Mr Dooley says the one “foolproof” way to make sure you're not swooped is by feeding magpies. “That's the way to a magpie's heart,” he said. “You don't want to give them junk food … fresh meat is the best or even dog biscuits, especially if they're soaked in a bit of water.”
Wear a hat or carry a stick or umbrella above your head. Cyclists should wear a helmet, dismount and walk through the area. Birds may be less likely to swoop if they think you are watching them.
If the bird was familiar with you being in its territory and viewed you as a food source and not a threat, the likelihood of the magpie swooping you would be reduced, Dr Jones said. “Only feed the birds if they are the ones next to where you live,” he said.
Remember, magpies are simply trying to protect their territory. Stay calm, protect your face and walk away quickly. A magpie may become aggressive towards people because it has been harassed in the past. Please do not throw things at magpies or chase them.
Some believe flashing lights scare them off, while others swear a zany wig, sticking eyes to the back of your head or opening an umbrella is the way to go. You could even attach a flag to your bike that is higher than your head.
– Wearing a hat and sunglasses or just holding something like a school bag above your head. – Some magpies only attack bike riders and will swoop on them even if they are outside the defence zone. If you get off your bike and walk, the magpie should leave you alone.
