Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Haliastur is a genus of medium-sized diurnal birds of prey. It consists of two species of kite which form part of the subfamily Milvinae; some authorities place these species in the genus Milvus, despite clear differences in behaviour, voice and plumage. Birds of prey are birds that hunt for food primarily on the wing, using their keen senses, especially vision. They are defined as birds that primarily hunt vertebrates, including other birds. Their talons and beaks tend to be relatively large, powerful and adapted for tearing and/or piercing flesh. In most cases, the females are considerably larger than the males. The term "raptor" is derived from the Latin word "rapere" (meaning to seize or take by force) and may refer informally to all birds of prey, or specifically to the diurnal group. Because of their overall large size and predatory lifestyle, they face distinct conservation concerns.
