Again, magpie attacks.
Got into Mackay just before tropical downpour.   Weather pattern emerging.   Dry mornings, wet afternoons.

  1. Magpies are ubiquitous in urban areas all over Australia, and have become accustomed to people. A small percentage of birds become highly aggressive during breeding season from late August to early October, and will swoop and sometimes attack passersby. The percentage has been difficult to estimate but is significantly less than 9%.[81] Almost all attacking birds (around 99%) are male,[82] and they are generally known to attack pedestrians at around 50 m (150 ft) from their nest, and cyclists at around 100 m (300 ft).[83] Attacks begin as the eggs hatch, increase in frequency and severity as the chicks grow, and tail off as the chicks leave the nest.[84]

    These magpies may engage in an escalating series of behaviours to drive off intruders. Least threatening are alarm calls and distant swoops, where birds fly within several metres from behind and perch nearby. Next in intensity are close swoops, where a magpie will swoop in from behind or the side and audibly "snap" their beaks or even peck or bite at the face, neck, ears or eyes. More rarely, a bird may dive-bomb and strike the intruder's (usually a cyclist's) head with its chest. A magpie may rarely attack by landing on the ground in front of a person and lurching up and landing on the victim's chest and peck at the face and eyes.[85]

    Attaching a long pole with a flag to a bike is an effective deterrent.[92] As of 2008, the use of cable ties on helmets has become common and appears to be effective.[93] Magpies prefer to swoop at the back of the head; therefore, keeping the magpie in sight at all times can discourage the bird. Using a basic disguise to fool the magpie as to where a person is looking (such as painting eyes on a hat, or wearing sunglasses on the back of the head) can also prove effective. In some cases, magpies may become extremely aggressive and attack people's faces; it may become very difficult to deter these birds from swooping. Another popular way to deter these birds is to put two fingers pointing out from the back of the head when walking in close range; this confuses them. Once attacked, shouting aggressively and waving one's arms at the bird should deter a second attack.
