The Apostlebird (Struthidea cinerea), also known as the Grey Jumper, is a quick-moving, gray or black bird about 33 centimetres long. It is a native to Australia where it roams woodlands, eating insects and seeds at, or near, ground level. Apostlebirds always seem to travel in groups of about 12; for this reason they were named after the Biblical apostles - the twelve chief followers of Jesus Christ.
