The white-fronted bee-eater (Merops bullockoides) is a species of bee-eater widely distributed in sub-equatorial Africa.
The species has a distinctive white forehead, a square tail, and a bright red patch on its throat. It nests in small colonies, digging holes in cliffs or earthen banks, and can usually be seen in low trees, waiting to hunt passing insects by making quick hawking flights or gliding down before hovering briefly to catch the prey.
This species, like other bee-eaters, is a richly coloured, slender bird, but with a distinctive black mask, white forehead, square tail and a bright red throat. The size is 23 cm (9 in.). The upperparts are green, with cinnamon underparts. The call is a deep squeak. [2]
White-fronted bee-eaters are found in the vast savannah regions of sub-equatorial Africa. The habitat commonly consists of open country, often near gullies, where bees, their prey, live.
White-fronted bee-eaters nest in colonies averaging 200 individuals, digging, roosting, and nesting holes in cliffs or banks of earth. A population of bee-eaters may range across many square kilometres of savannah, but will come to the same colony to roost, socialize, and to breed. White-fronted bee-eaters have one of the most complex family-based social systems found in birds.
Colonies comprise socially monogamous, extended family groups with overlapping generations, known as "clans", which exhibit cooperative breeding. Non-breeding individuals become helpers to relatives and assist to raise their brood. In white-fronted bee-eaters, this helping behavior is particularly well developed, with helpers assisting in half of all nesting attempts. [3] These helpers may contribute to all aspects of the reproductive attempt, from digging the roosting or nesting chamber, to allofeeding the female, incubating and feeding the young; and have a large effect on increasing the number of young produced. [4]
Only 50% of non-breeders in a colony typically become helpers, and whether or not an individual becomes a helper and to whom it provides aid is heavily dependent on the degree of kinship involved. Non-breeders are most likely to become helpers when breeding pairs are genetically close relatives. When faced with a choice of potential recipient nests, helpers preferentially help the breeding pair to whom they are most closely related, suggesting that this behaviour may serve to increase the helper's inclusive fitness.
Female white-fronted bee-eaters leaving their nesting burrows must avoid pursuit by unmated males who may force them to the ground and rape them. Furthermore, their unwelcome attentions are preferentially against females who are laying eggs and who thus might lay the eggs of their rapist rather than their mate. [5]
Their diet is made up primarily of bees, but they also take other flying insects depending on the season and availability of prey. Two hunting methods have been observed. They either make quick hawking flights from lower branches of shrubs and trees, or glide slowly down from their perch and hover briefly to catch insects.
The bee-eaters are a group of birds in the family Meropidae, containing three genera and thirty species. Most species are found in Africa and Asia, with a few in southern Europe, Australia, and New Guinea. They are characterised by richly coloured plumage, slender bodies, and usually elongated central tail feathers. All have long down-turned bills and medium to long wings, which may be pointed or round. Male and female plumages are usually similar.
The swallows, martins, and saw-wings, or Hirundinidae, are a family of passerine songbirds found around the world on all continents, including occasionally in Antarctica. Highly adapted to aerial feeding, they have a distinctive appearance. The term "swallow" is used colloquially in Europe as a synonym for the barn swallow. Around 90 species of Hirundinidae are known, divided into 19 genera, with the greatest diversity found in Africa, which is also thought to be where they evolved as hole-nesters. They also occur on a number of oceanic islands. A number of European and North American species are long-distance migrants; by contrast, the West and South African swallows are nonmigratory.
The European bee-eater is a near passerine bird in the bee-eater family, Meropidae. It breeds in southern and central Europe, northern and southern Africa, and western Asia. Except for the resident southern African population, the species is strongly migratory, wintering in tropical Africa. This species occurs as a spring overshoot north of its usual range, with occasional breeding in northern Europe.
The blue-cheeked bee-eater is a near passerine bird in the bee-eater family, Meropidae. The genus name Merops is Ancient Greek for "bee-eater", and persicus is Latin for "Persian".
The blue-tailed bee-eater is a near passerine bird in the bee-eater family Meropidae. It is widely distributed across South and Southeast Asia where many populations are strongly migratory, and seen seasonally in many parts but breeding colonially in small areas across their range, mostly in river valleys, where they nest by tunneling into loamy sand banks. They are seen mostly in open habitats close to water.
The little bee-eater is a bird species in the bee-eater family, Meropidae. They are found in Sub-Saharan Africa. They should not be confused with the little green bee-eater. Migration is limited to seasonal movements depending on rainfall patterns.
The Asian green bee-eater, also known as little green bee-eater, and green bee-eater in Sri Lanka, is a near passerine bird in the bee-eater family. It is resident but prone to seasonal movements and is found widely distributed across Asia from coastal southern Iran east through the Indian subcontinent to Vietnam. Populations in Africa and the Arabian Peninsula that were formerly assigned to this species are now considered distinct species: the African green bee-eater and the Arabian green bee-eater. They are mainly insect eaters and they are found in grassland, thin scrub and forest often quite far from water. Several regional plumage variations are known and several subspecies have been named.
The swallow-tailed bee-eater is a near passerine bird in the bee-eater family, Meropidae.
Forster's tern is a tern in the family Laridae. The genus name Sterna is derived from Old English "stearn", "tern", and forsteri commemorates the naturalist Johann Reinhold Forster.
The chestnut-headed bee-eater, or bay-headed bee-eater, is a near passerine bird in the bee-eater family Meropidae. It is a resident breeder in the Indian subcontinent and adjoining regions, ranging from India east to Southeast Asia.
The white-throated bee-eater is a near passerine bird in the bee-eater family, Meropidae. It breeds in semi-desert along the southern edge of the Sahara, Africa. The white-throated bee-eater is migratory, wintering in a completely different habitat in the equatorial rain forests of Africa from southern Senegal to Uganda.
The river martins form a distinctive subfamily Pseudochelidoninae within the swallow and martin bird family Hirundinidae. The two species are the African river martin Pseudochelidon eurystomina, found in the Congo and Gabon, and the white-eyed river martin Pseudochelidon sirintarae, known only from one site in Thailand. These are medium-sized, largely black swallows that have a light buoyant flight and feed on insects caught in the air. They appear to be more terrestrial than other swallows, frequently walking rather than perching, and the white-eyed may be crepuscular. The African species excavates nest holes in sandy ridges in rivers, while the breeding locations and habits of the Asian bird are unknown.
The rainbow bee-eater is a near passerine bird in the bee-eater family Meropidae.
The northern carmine bee-eater is a brightly-coloured bird in the bee-eater family, Meropidae. It is found across northern tropical Africa, from Senegal eastwards to Somalia, Ethiopia and Kenya. It was formerly considered to be conspecific with the southern carmine bee-eater which has a carmine coloured throat rather than the blue throat of the northern species.
The southern carmine bee-eater is a species of bee-eater found across sub-equatorial Africa. It was formerly considered conspecific with the closely related northern carmine bee-eater, with the combined species then known as carmine bee-eater.
A bird colony is a large congregation of individuals of one or more species of bird that nest or roost in proximity at a particular location. Many kinds of birds are known to congregate in groups of varying size; a congregation of nesting birds is called a breeding colony. Colonial nesting birds include seabirds such as auks and albatrosses; wetland species such as herons; and a few passerines such as weaverbirds, certain blackbirds, and some swallows. A group of birds congregating for rest is called a communal roost. Evidence of colonial nesting has been found in non-neornithine birds (Enantiornithes), in sediments from the Late Cretaceous (Maastrichtian) of Romania.
The rosy bee-eater is a species of bird in the family Meropidae. It is found in Angola, Benin, Burkina Faso, Republic of the Congo, Democratic Republic of the Congo, Ivory Coast, Equatorial Guinea, Gabon, Ghana, Nigeria, and Togo.
The blue-breasted bee-eater is a central African species of bird. It is a member of the family Meropidae. Meropids are all visually similar and have a diet specialized in Hymenopterans.
The Fiji woodswallow is a species of woodswallow in the family Artamidae. It is endemic to most of the islands of Fiji, although it is absent from Kadavu Archipelago and the Lau Archipelago. The species was once considered a race of the white-breasted woodswallow, which breeds from Australia, New Caledonia and Vanuatu through to Borneo and the Philippines. Some authors retain it in that species.
The Ethiopian bee-eater is a species of bird in the family Meropidae. It is found in Ethiopia and Sudan. It was formerly considered a subspecies of the blue-breasted bee-eater.
