Grey Butcherbird killings in Brisbane

["Philip Veerman" <>]

That Magpies are common in almost all cities and I have never heard of this, 
suggests it does hardly happen, if at all. They would probably find it hard for 
two reasons, they don't have a hooked beak and they may have difficulties 
hanging on the side of the cage, as they are a lot heavier. They do sometimes 
chase other small birds but cases of magpie predation on other birds are rare. 
I'd suggest Currawongs as more likely contenders than Magpies. They are all 
closely related and it is all possible.
