Australian Magpie is a medium-sized black and white passerine bird native to Australia and southern New Guinea. A member of the Cracticidae, it is closely related to the butcherbirds. The adult magpie is a fairly solid, sturdy bird ranging from 37 to 43 cm (14.5–17 in) in length with a 65–85 cm (26–33 in) wingspan, and weighing 220–350 g (8–12 oz). Its robust wedge-shaped bill is bluish-white bordered with black, with a small hook at the tip. The black legs are long and strong. The plumage is pure glossy black and white; both sexes of all subspecies have black heads, wings and underparts with white shoulders.
The magpie is generally sedentary and territorial throughout its range, living in groups occupying a territory, or in flocks or fringe groups. A group may occupy and defend the same territory for many years. Much energy is spent defending a territory from intruders, particularly other magpies, and different behaviours are seen with different opponents.
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%. Almost all attacking birds (around 99%) are male, 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). Attacks begin as the eggs hatch, increase in frequency and severity as the chicks grow, and tail off as the chicks leave the nest.
I only made an ID as the iPhone app was not showing a scientific name for you female Magpie.
