It is about the size of a chicken with blue/grey coloured feathers and an orange belly and legs.
There is a white ring on the back of its neck and a white fleck on its tail.
It has a black beak and yellow feet and very small eyes.
It caught and killed a sparrow, plucked it and moved it elsewhere to eat it, and is now cleaning itself.
Can you help with finding what type it is?
