Species of bird

The blue tailed bee eater (Merops philippinus) is a near passerine bird in the bee eater family Meropidae. It is widely distributed across South and Southeast Asia where many populations are strongly migratory, and seen seasonally in many parts but breeding colonially in small areas across their range, mostly in river valleys, where they nest by tunneling into loamy sand banks. They are seen mostly in open habitats close to water.

This species, like other bee eaters, is a richly coloured, slender bird. It is predominantly green; its face has a narrow blue patch with a black eye stripe, and a yellow and brown throat; the tail is blue and the beak is black. The three outer toes are united around their bases. It can reach a length of 23–26 cm, including the two elongated central tail feathers which can be just two inches more than the remaining ten feathers. Sexes are alike. This species is usually found near water and like other bee eaters it predominantly eats flying insects, especially bees (as large as the Xylocopa sp. ), wasps and hornets, which are caught in the air by sorties from an open perch. They may also forage in flight over estuaries, backwaters and even over the sea but not far from the coast. This species probably takes bees and dragonflies in roughly equal numbers. The insects that are caught are beaten on the perch to kill and break the exoskeleton. This habit is seen in many other members of the order Coraciiformes. They call mainly in flight with a rolling chirping whistling They also prefer clear mud banks without any vegetation cover. In Sri Lanka, they have been noted to breed in artificial sand dunes created by dredging of sea sand. The nest tunnel can run nearly 2 metres deep. About 5 to 7 near spherical eggs are laid. Both the male and the female take care of the eggs. The parents guard the nest to prevent intraspecific brood parasitism and extra pair copulation. These birds also feed and roost communally. Although males and females appear similar to the human eye, males tend to have longer central tail feather extensions and UV reflectance studies demonstrate that healthy males had darker chestnut throats and brighter green body plumage while females showed brighter blue rumps and yellow chins.

This species has sometimes been considered to be conspecific with the blue cheeked bee eater which is a close sister taxon, the two forming a clade with the Madagascan olive bee eater. In the past the species has been treated variously as M. persicus javanicus, M. superciliosus javanicus, and M. superciliosus philippinus. A species of feather louse, Brueelia superciliosa has been described from hosts of this species in Thailand.

The species has a patchy breeding distribution across India, Myanmar, and parts of Southeast Asia. In India they are known to breed in several of the river valleys including those of the Godavari, Kaveri, Tunga Badra and Krishna rivers. They also nest in the eastern parts of Sri Lanka. (southern Thailand). They are winter visitors in parts of Malaysia and peninsular India. The non breeding ranges of the blue cheeked bee eater and blue tailed overlap in some parts of Gujarat and western peninsular India.

The Blue tailed bee eater is listed as a species of least concern by the International Union for Conservation of Nature.
