Green Bee-eater (Merops orientalis) (sometimes Little Green Bee-eater)

The Green Bee-eater (Merops orientalis) (sometimes Little Green Bee-eater) is a near passerine bird in the bee-eater family. It is resident but prone to seasonal movements and is found widely distributed across sub-Saharan Africa from Senegal and The Gambia to Ethiopia, the Nile valley, western Arabia and Asia through India to Vietnam.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.

Like other bee-eaters, this species is a richly coloured, slender bird. It is about 9 inches (16--18 cm) long with about 2 inches made up by the elongated central tail-feathers. The sexes are not visually distinguishable. The green bee-eater also has a long, but sharp and narrow black beak which is perfectly designed for catching flying insects.

This species often hunts from low perches, maybe only a metre or less high. They readily make use of fence wires and electric wires. Before eating its meal, a bee-eater removes the sting by repeatedly hitting the insect on a hard surface.

Like other species in the genus, bee-eaters predominantly eat insects, especially bees, wasps and ants, which are caught in the air by sorties from an open perch. Before swallowing prey, a bee-eater removes stings and breaks the exoskeleton of the prey by repeatedly thrashing it on the perch.They feed on flying insects and can sometimes be nuisance to bee-keepers.

The green bee-eater is also known to sand-bathe more frequently than other bee-eater species and will sometimes bathe in water by dipping into water in flight. Green bee-eaters are usually seen in small groups and often roost communally in large numbers of up to 300 birds.
