The rufous-bellied heron (Ardeola rufiventris) is a species of heron in the genus Ardeola , the pond herons, of the family Ardeidae. It is found in southern Africa.
The rufous-bellied heron was formally described in 1850 by the Swedish zoologist Carl Jakob Sundevall from specimens collected along the Mooi River near Potchefstroom in South Africa. Sundevall coined the binomial name Ardea rufiventris. [2] [3] The specific epithet rufiventris combines Latin rufus meaning "ruddy" or "rufous" with venter, ventris meaning "belly". [4] The rufous-bellied heron is now placed in the genus Ardeola that was introduced in 1822 by the German naturalist Friedrich Boie. The species is monotypic: no subspecies are recognised. [5]
This is a small dark species of heron with a dark grey head, back and breast contrasting with a rufous belly, wings and tail. When seen in flight the bright yellow legs and feet contrast with the dark feathers of the underside of the body. Juveniles are paler and browner, darkening as they mature. [6]
It is found in eastern, central and southern sub-Saharan Africa widespread although absent from the arid south-west and is found in Angola, Botswana, Burundi, Democratic Republic of the Congo, Eswatini, Kenya, Lesotho, Malawi, Mali, Mozambique, Namibia, Rwanda, South Africa, Tanzania, Uganda, Zambia, and Zimbabwe.
It is found in seasonally flooded grasslands, marshes, flood-plains and inland deltas (e.g. the Okavango Delta), shallow water along riverbanks and lake shores, stands of papyrus, reedbeds and paddies.
This is a skulking species which when hiding assumes a bittern-like posture but with its bill in a horizontal rather than vertical position. It usually prefers to hunt on the landward side of well vegetated wetlands and in the shallow water. It is a largely sedentary species, which may make partial migratory movements to follow rainy season inundations of flood-plains.
Breeding occurs during the rainy season, or when flooding is at a peak where this occurs early in the dry season. It nests colonially in mixed colonies, typically in small groups of 6-30 pairs, although at Lake Bangwelu in Zambia, groups of 60-80 pairs have been recorded. Rufous-bellied herons feed during the day but will sometimes forage at night, normally they hunt alone or in small flocks of no more than five individuals, although aggregations of over 120 have been recorded. It prefers to roost in trees. [7] The nest is a small platform of vegetation positioned low in reeds, trees or shrubs that are normally positioned over standing water. In mixed-species colonies rufous-bellied herons normally nest around the edges. [1]
The diet consists mainly of small fish such as tilapia and barbus, amphibians, crustaceans, aquatic insects and other aquatic invertebrates.
The little grebe, also known as dabchick, is a member of the grebe family of water birds. The genus name is from Ancient Greek takhus "fast" and bapto "to sink under". The specific ruficollis is from Latin rufus "red" and Modern Latin -collis, "-necked", itself derived from Latin collum "neck".
The glossy ibis is a water bird in the order Pelecaniformes and the ibis and spoonbill family Threskiornithidae. The scientific name derives from Ancient Greek plegados and Latin, falcis, both meaning "sickle" and referring to the distinctive shape of the bill.
The grey heron is a long-legged wading bird of the heron family, Ardeidae, native throughout temperate Europe and Asia, and also parts of Africa. It is resident in much of its range, but some populations from the more northern parts migrate southwards in autumn. A bird of wetland areas, it can be seen around lakes, rivers, ponds, marshes and on the sea coast. It feeds mostly on aquatic creatures which it catches after standing stationary beside or in the water, or stalking its prey through the shallows.
The purple heron is a wide-ranging heron species. It breeds in Africa, central and southern Europe, and southern and eastern Palearctic. The Western Palearctic populations migrate between breeding and wintering habitats whereas the African and tropical-Asian populations are primarily sedentary, except for occasional dispersive movements.
The little egret is a species of small heron in the family Ardeidae. It is a white bird with a slender black beak, long black legs and, in the western race, yellow feet. As an aquatic bird, it feeds in shallow water and on land, consuming a variety of small creatures. It breeds colonially, often with other species of water birds, making a platform nest of sticks in a tree, bush or reed bed. A clutch of three to five bluish-green eggs is laid and incubated by both parents for about three weeks. The young fledge at about six weeks of age.
The ferruginous duck, also known as ferruginous pochard, common white-eye or white-eyed pochard, is a medium-sized diving duck from Eurosiberia. The scientific name is derived from Greek aithuia an unidentified seabird mentioned by authors including Hesychius and Aristotle, and nyrok, the Russian name for a duck.
The Eurasian spoonbill, or common spoonbill, is a wading bird of the ibis and spoonbill family Threskiornithidae. The genus name Platalea is from Latin and means "broad", referring to the distinctive shape of the bill, and leucorodia is from Ancient Greek leukerodios "spoonbill", itself derived from leukos, "white" and erodios "heron". In England it was traditionally known as the "shovelard", a name later used for the Northern Shoveller.
The squacco heron is a small heron, 44–47 cm long, of which the body is 20–23 cm (8–9 in), with 80–92 cm wingspan. It is of Old World origins, breeding in southern Europe and the Greater Middle East.
The pink-backed pelican is a bird of the pelican family. It is a resident breeder in the swamps and shallow lakes of Africa and southern Arabia; it has also apparently been extirpated from Madagascar.
The black-headed heron is a wading bird of the heron family Ardeidae, common throughout much of sub-Saharan Africa and Madagascar. It is mainly resident, but some west African birds move further north in the rainy season.
The black heron, also known as the black egret, is an African heron. It is well known for its habit of using its wings to form a canopy when fishing.
Nycticorax is a genus of night herons. The name Nycticorax means "night raven" and derives from the Ancient Greek νύκτος, nuktos "night" and κοραξ, korax, "raven". It refers to the largely nocturnal feeding habits of this group of birds, and the croaking crow-like call of the best known species, the black-crowned night heron.
The night herons are medium-sized herons, 58–65 cm, in the genera Nycticorax, Nyctanassa, and Gorsachius. The genus name Nycticorax derives from the Greek for "night raven" and refers to the largely nocturnal feeding habits of this group of birds, and the croaking crow-like, almost like a barking sound, call of the best known species, the black-crowned night heron.
The nankeen night heron is a heron that belongs to the genus Nycticorax and the family Ardeidae. Due to its distinctive reddish-brown colour, it is also commonly referred to as the rufous night heron. It is primarily nocturnal and is observed in a broad range of habitats, including forests, meadows, shores, reefs, marshes, grasslands, and swamps. The species is 55 to 65 cm in length, with rich cinnamon upperparts and white underparts. The nankeen night heron has a stable population size, and is classified as a species of least concern by the International Union for Conservation of Nature (IUCN).
The slaty egret is a small, dark egret found in southern Africa. It is one of the species to which the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA) applies. It is classified as Vulnerable, the biggest threat being habitat loss.
The African marsh harrier is a bird of prey belonging to the harrier genus Circus. It is largely resident in wetland habitats in southern, central and eastern Africa from South Africa north to South Sudan.
Pond herons (Ardeola) are herons, typically 40–50 cm (16–20 in) long with an 80–100 cm (30–40 in) wingspan. Most breed in the tropical Old World, but the migratory squacco heron occurs in southern Europe and the Middle East and winters in Africa. The scientific name comes from Latin ardeola, a small heron (ardea).
The rufous-breasted sparrowhawk, also known as the rufous-chested sparrowhawk and as the red-breasted sparrowhawk, is a species of bird of prey in the family Accipitridae. It is found in Angola, Democratic Republic of the Congo, Eritrea, Eswatini, Ethiopia, Kenya, Lesotho, Malawi, Mozambique, Rwanda, South Africa, South Sudan, Tanzania, Uganda, Zambia, and Zimbabwe.
The rock pratincole is a species of bird in the family Glareolidae.
The eastern cattle egret is a species of heron found in the tropics, subtropics and warm temperate zones. Most taxonomic authorities lump this species and the western cattle egret together as subspecies of the cattle egret, but some separate them. Despite the similarities in plumage to the egrets of the genus Egretta, it is more closely related to the herons of Ardea. It is native to southern and eastern Asia, and Australasia.
