Indian Courser

Identification

This courser is widespread in South Asia and overlaps with some other species such as the similar looking cream-colored courser. This species is however brighter coloured than the cream-coloured courser and has a broader black eye-stripe that begins at the base of the beak. The crown is chestnut and the breast is rufous. The nape has a dark black patch where the long longer feathers forming the white stripe meet. In flight, the rump appears white and the wing tip is not as contrastingly black as in the cream-coloured courser. The sexes are alike.<p>The long legs are whitish and as in other coursers have only three forward pointing toes.<p>The species is closely related to other coursers in the region and are considered to form a superspecies with Cursorius cursor, Cursorius rufus and Cursorius temminckii.

Taxonomy

The Indian courser was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae. He placed it with the plovers in the genus Charadrius and coined the binomial name Charadrius coromandelicus. Gmelin based his description on the "Coromandel plover" that had been described in 1785 by the English ornithologist John Latham in his A General Synopsis of Birds. Latham in turn based his own description on a hand-coloured print that accompanied Comte de Buffon's Histoire Naturelle des Oiseaux . The Indian courser is now placed in the genus Cursorius that was introduced by Latham in 1790. The genus name is from Latin cursor meaning "runner", from currere, "to run". The specific epithet is from the Coromandel Coast of India, the type locality. The species is monotypic: no subspecies are recognised.

Range and habitat

This species occurs in dry stony, scrubby or rocky country but rarely on sandy terrain from the Indus valley east short of Bangladesh and south to the tip of Peninsular India. It sometimes occurs in the dry zone of northern Sri Lanka. The wet forest zones are avoided. In southern India, the drier zone on the east coast, the Coromandel region, where it is not uncommon gives it the species name. It is also found patchily distributed in other parts of the peninsula. Other areas where they are commonly seen include the Deccan plateau and the arid regions of northwestern India in Rajasthan and Gujarat. It is resident in some areas but makes local movements.

Behavior

These birds are usually seen in small flocks. They are usually found where the grass is not taller than them, since the tall grass blocks their view. They feed on insects mainly termites, beetles, crickets and grasshoppers picked up from the ground in stubbly or uncultivated fields. They run in spurts on the ground but take to flight with a hoarse creaky gwaat call. The flight is strong with rapid wing beats. They fly low and begin to run after landing.<p>They breed mainly from March to August. Records exist from mid May in southern India and Sri Lanka and mid April in Darbhanga. They nest in a scrape on bare stony ground laying 2 or 3 speckled and well-camouflaged eggs that are very spherical. The chicks are protectively coloured and on alarm crouch and remain immobile making them extremely difficult to spot. Adults do not call or display when the nest or chicks are approached. The chicks are able to move upon hatching but are initially fed by the parents and begin to forage on their own after a week.
