Merops apiaster

The European bee-eater (Merops apiaster) is a near passerine bird in the bee-eater family, Meropidae. It breeds in southern Europe and in parts of north Africa and western Asia. It is strongly migratory, wintering in tropical Africa. This species occurs as a spring overshoot north of its range, with occasional breeding in northwest Europe. The European bee-eater was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his Systema Naturae under its current binomial name Merops apiaster. The genus name Merops is Ancient Greek for 'bee-eater', and apiaster is Latin, also meaning 'bee-eater', from apis, 'bee'. This species, like other bee-eaters, is a richly coloured, slender bird. It has brown and yellow upper parts, whilst the wings are green and the beak is black. It can reach a length of 27–29 cm (10.6–11.4 in), including the two elongated central tail feathers. Sexes are alike. Female tends to have greener rather than gold feathers on shoulders. Non-breeding plumage is much duller and with a blue-green back and no elongated central tail feathers. Juvenile resembles a non-breeding adult, but with less variation in the feather colours. Adults begin to moult in June or July and complete the process by August or September. There is a further moult into breeding plumage in winter in Africa. These bee-eaters are gregarious—nesting colonially in sandy banks, preferably near river shores, usually at the beginning of May. They make a relatively long tunnel, in which they lay five to eight spherical white eggs around the beginning of June. Both male and female care for the eggs, which they brood for about three weeks. They also feed and roost communally. During courtship, the male feeds large items to the female while eating the small ones himself. Most males are monogamous, but occasional bigamy has been encountered. Their typical call is a distinctive, mellow, liquid and burry prreee or prruup. European bee-eaters have attempted to nest in Britain on at least 5 occasions: This bird breeds in open country in warmer climates. As the name suggests, bee-eaters predominantly eat insects, especially bees, wasps, and hornets. They catch insects in flight, in sorties from an open perch. Before eating a bee, the European bee-eater removes the sting by repeatedly hitting the insect on a hard surface. It can eat around 250 bees a day. The most important prey item in their diet is Hymenoptera, mostly Apis mellifera. A study in Spain found that these comprise 69.4% to 82% of the European bee-eaters' diet. Their impact on bee populations, however, is small. They eat less than 1% of the worker bees in areas where they live.
