These birds are very common around my yard. They eat a varied diet including nectar, insects and fruits. Sometimes they are called the Banana Bird. Their most striking feature is the large bare skin patch around the eye which in mature birds is a lovely bright blue color. In young birds it is greenish colored. I have cropped one of the photos to show this eye patch.
They are noisy and aggressive birds - both to other smaller birds and to anything else that they see as invading their territory. They leave my dog alone as she is not a bit scared of them but they have the cat terrified. If they manage to catch the cat out in the open then a whole group of them will fly around scolding and swooping and trying to peck her. Usually at this point the dog delights in rescuing the cat and seeing off the birds!
