Amusing footage shows an aggressive bird dive-bombing a stray cat after it wandered near its tree.<br /><br />In the video, the bird is seen striking the cat on its back while it slowly retreated away.<br /><br />Onlooker Junjun Onit said that the bird must be territorial so it felt alarmed that the cat invaded its space.<br /><br />He said: "The bird is smart. It is willing to protect its territory with all its might. This is the first time I have seen this kind of bird."<br /><br />The video was recorded in Junjun's neighbourhood in Pasay City, the Philippines on May 29.<br /><br />The bird in the video is a Pied Fantail, locally known as Maria Capra, usually found in the cities.<br /><br />They are extremely territorial and will attack animals, mostly cats and dogs but sometimes people, especially if it has a nest nearby.
