The bush stone-curlew or bush thick-knee, also known as the Iben bird (Burhinus grallarius, obsolete name Burhinus magnirostris) is a large, ground-dwelling bird endemic to Australia. Its favoured habitat is open plains and woodlands, where it stalks slowly at night in search of invertebrates such as insects. Its grey-brown coloration is distinguished by dark streaks, its eyes are large and legs are long. It is capable of flight, but relies on the camouflage of its plumage to evade detection during the day; the bush curlew adopts a rigid posture when it becomes aware of an observer. Both sexes care for two eggs laid on the bare ground, usually sited near bush in a shaded position or next to a fallen branch. Taxonomy The bush stone-curlew was first described by English ornithologist John Latham in 1801 under the binomial name Charadius grallarius. Latham published three names simultaneously; however, the seniority of C. grallarius follows the publication of the names in John Gould's Birds of Australia in 1845. Until a revision determining the priority of names assigned to this species, ornithologists cited the description under the epithet B. magnirostris. Descriptions of subspecies were published by Gregory Mathews in 1912, B. m. rufescens and B. m. broomei describing specimens collected in western Australia and B. m. ramsayi collected in the east at Queensland. These descriptions are recognised as synonymous with B. grallarius. A species of the widely distributed family Burhinidae, also represented in Australia by the beach stone-curlew Esacus magnirostris, it is terrestrial forager of semiarid inland environments related to the shorebirds and waders of the order Charadriiformes. Common names for this species are southern, bush, and scrub stone-curlew, the bush thick-knee, and southern stone plover. A name used by the indigenous peoples of Western Australia, wee-lo, was reported by John Gilbert and published by Gould in 1845. Later authorities included this name as current at the Northwest Cape and Southwest Australia, the similar wee-loo at Pallinup River, and welojabbin, also in the southwest, and windoo at a district in the western interior. Description A species of Burhinus, a genus of large-eyed and long-legged terrestrial foragers known as thick-knees, it is slender in form and a grey and brown colour with distinctive markings. The bird has conspicuous dark streaks over the buff and greyish white feathers of the upperparts and spotted markings on the wings. The plumage at lower side of the bird
