Hungry kangaroo knocks on the window of a house in Australia

The video footage shows a hungry kangaroo in Australia knocking on a house window for food. The kangaroo tries to get inside but does not succeed. Australia is home to a fascinating array of animals -- not just kangaroos but also favorites like koalas, wombats and duck-billed platypuses. Most of them are marsupials, carrying their young in pouches on their bodies until they can fend for themselves.
