About the Great Thick-knee

The great stone-curlew or great thick-knee (Esacus recurvirostris) is a large wader which is a resident breeder in tropical southern Asia from India, Pakistan, Sri Lanka, Bangladesh into South-east Asia. The great stone-curlew was formally described in 1829 by the French naturalist Georges Cuvier and given the binomial name Oedicnemus recurvirostris. The type locality is Nepal. The specific epithet recurvirostris combines Latin recurvis meaning "bent backwards" with -rostris meaning "-billed". The species is now placed in the genus Esacus that was introduced in 1831 to accommodate the great stone-curlew by the French naturalist René Lesson. The species is monotypic: no subspecies are recognised.
