Now, I would suspect that there are not too many Perth city folk that have seen an actual butcherbird (which may, or may, be supposed to be written as two words: viz, butcher bird). For those not attuned to decoding between magpies, mudlarks, and butcherbirds it can be a little confusing. A butcherbird is somewhat the same size as a mudlark, but perhaps a little shorter and a little pudgier.
Unlike mudlarks and magpies—which will eat things other than meat if they need too—butcherbirds are pretty much pure carnivores. No veg or cereal for them.
Where I hail from, up on the edge of the wheat growing belt inland from Geraldton, we often saw butcherbirds having a meal tearing apart a small field mouse or a wee lizard in the fork of a tree. But I have rarely spotted a butcherbird in suburbia. Even when I was living in bushy and bird friendly Kalamunda.
