Magpies

Magpie nesting season occurs between August and October each year. During this time magpies can swoop to protect their young from perceived threats. This is normal protective behaviour and magpies often target runners or bike riders as these activities appear threatening to them. They will typically respond to perceived threats by flying low and fast overhead and clacking their beaks as they pass. Some birds may even make contact. These occurrences are rare, but have the potential to cause injury.

Although magpies can sometimes cause fear, their behaviour is instinctive and intended to protect their offspring and provide them the best chance of survival. We investigate reports of swooping magpies to assess the bird’s behaviour on site. However, the magpie is a native species protected under the Western Australian Biodiversity Conservation Act 2016, and any actions required are determined on an individual basis.

To help reduce the risk of being swooped during the short breeding season we recommend:

• Avoiding the area if possible or take an alternate route for the weeks that the birds are nesting. Magpies typically defend a 100m radius around their nests.
• Do not act aggressively towards a magpie. Trying to hit or throw things at them will make the situation worse. Magpies have good memories and will swoop someone who has threatened them in the past.
• Dismount bikes and walk through the area. Fast moving bikes appear threatening to a nesting magpie.
• Do not stop if you are swooped upon. You are still in the magpie’s territory so they will continue to swoop until you are clear of the area.
• Wear a hat and sunglasses, or carry an umbrella for head and eye protection.

Southwestern snake-necked turtle monitoring

Many of the City’s wetlands are home to populations of the snake-necked turtle which are under threat from a combination of predators, such as foxes and ravens, vehicle strikes on our roads and a lack of suitable nesting habitat. 

How you can help

We have joined forces with Murdoch University and the South West Metropolitan Alliance to participate in the 'Saving Our Snake-Necked Turtle' project.  The project empowers citizen scientists with the knowledge and the skills to help save the snake-necked turtle by becoming a Turtle Tracker. 

Head to the City’s What’s On calendar to see when the next turtle information and training sessions will be held. 

About Southwestern snake-necked turtles

Scientific name: Chelodina colliei

Conservation status: Listed as 'near threatened' by the International Union for Conservation of Nature (IUCN).

Appearance: 

• Distinctive oblong shaped shell, dark brown to black in colour;
• Pale yellow underside;
• Olive grey skin with dark mottling;
• Streamlined head with a long neck that can grow up to 20cm in length; and
• Webbed feet with four claws.

Size: The shell length is usually up to 30cm and the total length can be up to 50cm.

Habitat: Freshwater wetlands, lakes and rivers, including urban lakes in the Perth metropolitan region and farm dams.

Diet: Adults are underwater apex predators, generalist feeders, and opportunistic carnivores. The diet changes seasonally and consists of a broad range of macro-invertebrates, carrion, frogs and fish. Hatchlings also eat aquatic plants as well as midge and mosquito larvae.

Major threats: Injury by road traffic, predation by foxes and dogs, fencing and barriers restricting migration, illegal fishing by humans, and fragmentation of natural habitat.
