Meropidae
27 species
The bee-eaters are a group of non-passerine birds in the family Meropidae, containing three genera and twenty-seven 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.
As their name suggests, bee-eaters predominantly eat flying insects, especially bees and wasps, which are caught on the wing from an open perch. The insect's stinger is removed by repeatedly hitting and rubbing the insect on a hard surface. During this process, pressure is applied to the insect's body, thereby discharging most of the venom.
Most bee-eaters are gregarious. They form colonies, nesting in burrows tunnelled into vertical sandy banks, often at the side of a river or in flat ground. As they mostly live in colonies, large numbers of nest holes may be seen together. The eggs are white, with typically five to the clutch. Most species are monogamous, and both parents care for their young, sometimes with assistance from related birds in the colony.
Bee-eaters may be killed by raptors; their nests are raided by rodents and snakes, and they can carry various parasites. Some species are adversely affected by human activity or habitat loss, but none meet the International Union for Conservation of Nature's vulnerability criteria, and all are therefore evaluated as "least concern". Their conspicuous appearance means that they have been mentioned by ancient writers and incorporated into mythology.
The bee-eaters have an Old World distribution, occurring from Europe to Australia. The centre of diversity of the family is Africa, although a number of species also occur in Asia. Single species occur in each of Europe, (the European bee-eater), Australia (the rainbow bee-eater) and Madagascar (the olive bee-eater, also found on mainland Africa). Of the three genera, Merops, which has the majority of the species, occurs across the entirety of the family's distribution. Nyctyornis is restricted to Asia, ranging from India and southern China to the Indonesian islands of Sumatra and Borneo. The genus Meropogon has a single species restricted to Sulawesi in Indonesia.
Bee-eaters are fairly indiscriminate in their choice of habitat. Their requirements are simply an elevated perch from which to watch for prey and a suitable ground substrate in which to dig their breeding burrow. Because their prey is entirely caught on the wing they are not dependent on any vegetation type. A single species, the blue-headed bee-eater, is found inside closed rainforest where it forages close to the ground in poor light in the gaps between large trees. Six other species are also closely associated with rainforest, but occur in edge habitat such as along rivers, in tree-fall gaps, off trees overhanging ravines or on emergent tree crowns above the main canopy.
Species that breed in subtropical or temperate areas of Europe, Asia and Australia are all migratory. The European bee-eaters that breed in southern Europe and Asia migrate to West and southern Africa. Another population of the same species breeds in South Africa and Namibia; these birds move northwards after breeding. In Australia the rainbow bee-eater is migratory in the southern areas of its range, migrating to Indonesia and New Guinea, but occurs year-round in northern Australia. Several species of bee-eater, are intra-African migrants; the white-throated bee-eater, for example, breeds on the southern edge of the Sahara and winters further south in equatorial rainforest. The most unusual migration is that of the southern carmine bee-eater, which has a three-stage migration; after breeding in a band between Angola and Mozambique it moves south to Botswana, Namibia and South Africa before moving north to its main wintering grounds in northern Angola, Congo and Tanzania.
