When I started this post I realised that was the second bird in a few posts where the common name has religious overtones - just a coincidence!
These are Apostlebirds (Struthidea cinerea). We were stopped in Katherine in the Northern Territory when I saw a flock of about 20 or 30 of these birds feeding in a small park. I quick dash over the road was in order.
The Apostlebird is common in some place on the eastern side of Australia - but you tend to find lots, or none at all. Katherine must be a 'lots' place. These birds were feeding in an area of grass that went from deep shade to bright sunshine in a few paces, which made photographing groups of them a bit of a challenge! The speed at which they move did not help either!
Apostlebirds are one of a number of species in Australia that breed in groups built around one breeding pair. Most of the other birds in the group are termed 'helpers' and are normally either the offspring of the pair, or closely related kin. Interestingly, some birds that are unrelated to the breeding pair are sometimes found in the group.
