Green Bee-Eater Early morning..

The green bee-eater (Merops orientalis) (sometimes little green bee-eater) is a near passerine bird in the bee-eater family.

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. Migration is not known but they make seasonal movements in response to rainfall. These birds are somewhat sluggish in the mornings and may be found huddled next to each other on wires sometimes with their bills tucked in their backs well after sunrise. They sand-bathe more frequently than other bee-eater species and will sometimes bathe in water by dipping into water in flight. They are usually seen in small groups and often roost communally in large numbers (200-300). The birds move excitedly at the roost site and call loudly, often explosively dispersing before settling back to the roost tree. The little green bee-eater is also becoming common in urban and sub-urban neighborhoods, and has been observed perching on television antennae, only to launch into a brief, zig-zag flight formation to catch an insect, then return to the same perch and consume the meal. This behaviour is generally observed between the hours of 7:00 and 8:00am, and after 4:00pm.

The breeding season is from March to June. Unlike many bee-eaters, these are often solitary nesters, making a tunnel in a sandy bank. The breeding pairs are often joined by helpers. They nest in hollows in vertical mud banks. The nest tunnel that they construct can run as much as 5 feet long and the 3-5 eggs are laid on the bare ground in the cavity at the end of the tunnel. The eggs are very spherical and glossy white.Clutch size varies with rainfall and insect food density. Both sexes incubate. The eggs hatch asynchronously with an incubation period of about 14 days and the chicks grow fledge in 3 to 4 weeks and in the fledging stage show a reduction in body weight.

A study suggested that green bee-eaters may be capable of interpreting the behaviour of human observers. They showed an ability to predict whether a human at a particular location would be capable of spotting the nest entrance and then behaved appropriately to avoid giving away the nest location. The ability to look at a situation from another’s point of view was previously believed to be possessed only by primates.

Riverside habitats were found to support high populations in southern India (157 birds per square kilometre) dropping off too 101 per km² in agricultural areas and 43-58 per square km near human habitations.

They feed on flying insects and can sometimes be nuisance to bee-keepers. The preferred prey was mostly beetles followed by hymenopterans. Orthopterans appear to be avoided. They are sometimes known to take crabs.Like most other birds they regurgitate the hard parts of their prey as pellets.

An endoparasitic nematode (Torquatoides balanocephala) sometimes infects their gizzard.A protozoal parasite in their blood, Haemoproteus manwelli, has been described from India.
