This is the native Noisy Miner Bird photographed at Tidbinbilla but common around the suburbs of Canberra. Unfortunately it is often confused with the introduced and destructive Indian Myna bird.

As you can see there are obvious differences on closer inspection. The introduced bird has a full black head with yellow markings of a different shape and the body colour is different. Basically not all birds with yellow eye patches and yellow beaks in Canberra are the same.
