The European bee-eater (Merops apiaster) is a near passerine bird in the bee-eater family Meropidae. The genus name Merops is Ancient Greek for "bee-eater", and apiaster is Latin, also meaning "bee-eater", from apis, "bee". 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.
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.
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.
A study found that European bee-eaters "convert food to body weight more efficiently if they are fed a mixture of bees and dragonflies than if they eat only bees or only dragonflies."
