Only dead or very young ones - they could not easily catch and kill one otherwise.
Magpies are birds that are part of the crow family. The biggest threat to them is bigger birds and humans.
they are blak with white paches and some times they hve a yellow beak :p
The eggs are white and are about 1.2 mm in length. Within a day, larvae (maggots) hatch from the eggs; they live and feed on (usually dead and decaying) organic material, such as garbage or feces. They are pale-whitish, 3-9 mm long, thinner at the mouth end, and have no legs. They live at least one week. At the end of their third instar, the maggots crawl to a dry, cool place and transform into pupae, colored reddish or brown and about 8 mm long. The adult flies then emerge from the pupae. (This whole cycle is known as complete metamorphosis.) The adults live from two weeks to a month in the wild, or longer in benign laboratory conditions. After having emerged from the pupae, the flies cease to grow; small flies are not necessarily young flies, but are instead the result of getting insufficient food during the larval stage.[3]The male mounts the female from behind
Some 36 hours after having emerged from the pupa, the female is receptive for mating. The male mounts her from behind to inject sperm. Copulation takes a few seconds to a couple of minutes.[3] Normally, the female mates only once, storing the sperm to use it repeatedly for laying several sets of eggs.
The simple answer is YES the Australian Magpie is a monogamous bird. Like many bird species they have just the one partner.
By checking out the pointy end of the beak. The less black there is, the older the magpie.
