average lifespan of the magpie is unknown, some individuals have been known to live for up to 30 years. For the magpies, we will guess around a ten year maximum, so roughly eight to one. They build large, domed nests in thorny bushes or high up in tall trees. Magpies usually breed from two years old, although some may breed at one year. And since magpies can live between 25 and 30 years and are territorial, they can develop lifelong friendships with humans. The gathering of raucously calling magpies (up to 40 birds have been observed) may last for 10 to 15 minutes before the birds disperse and fly off silently. Corvids, like magpies, crows and ravens and jays, are long lived birds, some to twenty years. In good conditions magpies can live up to 30 years, while in nature they live no more than 15 years. One of the most notable Black-billed Magpie behaviors is the so-called “funeral”—when one magpie discovers a dead magpie, it begins calling loudly to attract other magpies. The female lays on average six greenish-blue eggs, heavily spotted with brown, in April, and incubates them for 18 to 19 days. This bond can extend to trusting certain people around their offspring. Therefore, before you become attached to your new pet, seriously think about whether you are ready for such a long-term care of a bird or it is better to abandon such a pet.
