Magpie

Magpie are distinctive with black and white plumage and a long tail., with dark blue iridescent streaks in its wing feathers.

It is a noisy bird, with an annoying chattering.

Magpies seem to be jacks of all trades – scavengers, predators and pest-destroyers.  Despite their beauty they are not well-loved birds.

Non-breeding magpie will gather together in flocks.

They are omnivores and scavengers.

Magpies usually breed from two years old although some may breed at one year.

Breeding magpies hold a territory of about five hectares (12 acres) all year round.

Because nest sites are limited, between 25 to 60 per cent of magpies in an area do not breed.  Non-breeding birds often form flocks with a home range of up to 20 hectares (about 50 acres) and may pair up within the flock.

They build large, domed nests in thorny bushes or high up in tall trees.

The female lays on average six greenish-blue eggs, heavily spotted with brown, in April, and incubates them for 18 to 19 days.  During this time the male feeds her on the nest. Incubation starts in the middle of the laying period, so the earliest eggs hatch first.

Both parents feed the young.  If the food supply is poor, the stronger, older nestlings will get all of it.  This helps to ensure that at least some of them survive.

They fledge after 26 to 30 days, and are fed by the parents for a further four weeks after leaving the nest. 

The young birds stay in the parents’ territory until September or October, when they form loose flocks, feeding and roosting together.

During the winter, flocks may join to form large winter roosts. Some breeding birds may also join these roosts.  

The months following fledging are a dangerous time for young magpies, with a high percentage failing to make it through the first year.

If young birds survive to breed, their average life expectancy is around 3 years. S ome live much longer than this, with the oldest recorded being more than 21 years old.
