These large conspicuous birds are quite common and often allowed close approach. Not really a magpie or crow, they are actually a type of butcherbird (Artamidae). This species exhibits much geographic variation, with eight races in Australia divided into two main groups. Birds in the west and south are white on the back, while birds in the east, such as this, have black backs. Note also its broad black tail band. They form a hybrid zone where they meet. They were formerly split into separate species and sometimes placed in the genus Cracticus. Canon PowerShot SX60 HS.
