Cattle Egrets, buffaloes and a raptor in Kaziranga National Park, Assam.
The cattle egret (Bubulcus ibis) is a cosmopolitan species of heron (family Ardeidae) found in the tropics, subtropics and warm temperate zones. It is the only member of the monotypic genus Bubulcus, although some authorities regard its two subspecies as full species, the western cattle egret and the eastern cattle egret. Despite the similarities in plumage to the egrets of the genus Egretta, it is more closely related to the herons of Ardea. Originally native to parts of Asia, Africa and Europe, it has undergone a rapid expansion in its distribution and successfully colonised much of the rest of the world.
It is a white bird adorned with buff plumes in the breeding season. It nests in colonies, usually near bodies of water and often with other wading birds. The nest is a platform of sticks in trees or shrubs. Cattle egrets exploit drier and open habitats more than other heron species. Their feeding habitats include seasonally inundated grasslands, pastures, farmlands, wetlands and rice paddies. They often accompany cattle or other large mammals, catching insect and small vertebrate prey disturbed by these animals. Some populations of the cattle egret are migratory and others show post-breeding dispersal.
The water buffalo or domestic Asian water buffalo (Bubalus bubalis) is a large bovid found on the Indian subcontinent to Vietnam and Peninsular Malaysia, in Sri Lanka, in the Philippines, and in Borneo.
The wild water buffalo (Bubalus arnee) native to Southeast Asia is considered a different species but most likely represents the ancestor of the domestic water buffalo.
Two extant types of water buffalo are recognized based on morphological and behavioural criteria -- the river buffalo of the Indian subcontinent and further west to the Balkans, Egypt and Italy, and the swamp buffalo, found from Assam in the west through Southeast Asia to the Yangtze valley of China in the east. The origins of the domestic water buffalo types are debated, although results of a phylogenetic study indicate that the swamp type may have originated in China and domesticated about 4,000 years ago, while the river type may have originated from India and was domesticated about 5,000 years ago.
Birds of prey, also known as raptors, hunt and feed on other animals. The term "raptor" is derived from the Latin word rapere (meaning to seize or take by force). These birds are characterized by keen vision that allows them to detect prey during flight and powerful talons and beaks. In most cases, the females are larger than the males. Because of their predatory nature, they face distinct conservation concerns.
Many species of birds may be considered partly or exclusively predatory. However, in ornithology, the term "bird of prey" applies only to birds of the families listed below. Taken literally, the term "bird of prey" has a wide meaning that includes many birds that hunt and feed on animals and also birds that eat very small insects. In ornithology, the definition for "bird of prey" has a narrower meaning: birds that have very good eyesight for finding food, strong feet for holding food, and a strong curved beak for tearing flesh. Most birds of prey also have strong curved talons for catching or killing prey. An example of this difference in definition, the narrower definition excludes storks and gulls, which can eat quite large fish, partly because these birds catch and kill prey entirely with their beaks, and similarly bird-eating skuas, fish-eating penguins, and vertebrate-eating kookaburras are excluded. Birds of prey generally prey on vertebrates, which are usually quite large relative to the size of the bird. Most also eat carrion, at least occasionally, and vultures and condors eat carrion as their main food source.
