Noisy Miner

No, they haven't started fracking the paddock, a Noisy Miner is a dicky bird.

These are very common around the paddock as they are a species that has benefited from human development. They like the types of plants humans tend to like and grow. They hang around in organised mobs, terrorising smaller dicky birds and ganging up on bigger dickies.
Don't be looking out for elaborate mating rituals - they're into occasional orgies for reproduction. There is also a very good and hopefully self explanatory reason they are called noisy.
