The stone-curlews, also known as dikkops or thick-knees, consist of 10 species within the family Burhinidae, and are found throughout the tropical and temperate parts of the world, with two or more species occurring in some areas of Africa, Asia, and Australia. Despite the group being classified as waders, most species have a preference for arid or semiarid habitats.
Taxonomy
The family Burhinidae was introduced in 1912 for the stone-curlews by Australian ornithologist Gregory Mathews.{{ cite journal | last=Mathews | first=Gregory | author-link=Gregory Mathews | year=1912 | journal=Novitates Zoologicae | title=A reference-list to the birds of Australia | volume=18 | issue=3 | pages=171-455 [225] | url=https://www.biodiversitylibrary.org/page/3109569 }}{{cite book | last=Bock | first=Walter J. | year=1994 | title=History and Nomenclature of Avian Family-Group Names | series=Bulletin of the American Museum of Natural History | volume= 222 | publisher=American Museum of Natural History | place=New York | pages=112–113, 137, 247 | url=http://digitallibrary.amnh.org/handle/2246/830 }} The family contains three genera: Hesperoburhinus, Burhinus and Esacus.{{cite web| editor1-last=Gill | editor1-first=Frank | editor1-link=Frank Gill (ornithologist) | editor2-last=Donsker | editor2-first=David | editor3-last=Rasmussen | editor3-first=Pamela | editor3-link=Pamela Rasmussen | date=January 2021 | title=Buttonquail, thick-knees, sheathbills, plovers, oystercatchers, stilts, painted-snipes, jacanas, Plains-wanderer, seedsnipes | work=IOC World Bird List Version 11.1 | url=https://www.worldbirdnames.org/bow/buttonquail/ | publisher=International Ornithologists' Union | accessdate=29 May 2021 }} The name Burhinus combines the Ancient Greek bous meaning "ox" and rhis, rhinos meaning "nose" (or "bill").{{cite book | last=Jobling | first=James A. | year=2010| title=The Helm Dictionary of Scientific Bird Names | publisher=Christopher Helm | location=London | isbn=978-1-4081-2501-4 | page=81 }}
Molecular phylogenetic studies have shown that the family Burhinidae is sister to a clade containing the sheathbills in the family Chionidae and the Magellanic plover in its own family Pluvianellidae. The stone-curlews are not closely related to the curlews, genus Numenius, that belong to the sandpiper family Scolopacidae.{{Cite journal | last1=Kuhl | first1=H. | last2=Frankl-Vilches | first2=C. | last3=Bakker | first3=A. | last4=Mayr | first4=G. | last5=Nikolaus | first5=G. | last6=Boerno | first6=S.T. | last7=Klages | first7=S. | last8=Timmermann | first8=B. | last9=Gahr | first9=M. | date=2020 | title=An unbiased molecular approach using 3′-UTRs resolves the avian family-level tree of life | journal=Molecular Biology and Evolution | issue=msaa191 | doi=10.1093/molbev/msaa191 | doi-access=free | pmc=7783168 }}
Description
They are medium to large birds with strong black or yellow black bills, large yellow eyes—which give them a reptilian appearance—and cryptic plumage. The names thick-knee and stone-curlew are both in common use. The term stone-curlew owes its origin to the broad similarities with true curlews. Thick-knee refers to the prominent joints in the long yellow or greenish legs and apparently originated with a name coined in 1776 for B. oedicnemus, the Eurasian stone-curlew.
Obviously the heel (ankle) and the knee are confused here.{{cite book |last=Kochan |first=Jack B. |series=Birds |title=Feet & Legs |publisher=Stackpole Books |location=Mechanicsburg |year=1994 |isbn=0-8117-2515-4 }}
Behaviour
They are largely nocturnal, particularly when singing their loud, wailing songs, which are reminiscent of true curlews.{{cite book |editor=Forshaw, Joseph|author= Harrison, Colin J.O.|year=1991|title=Encyclopaedia of Animals: Birds|publisher= Merehurst Press|location=London|pages= 105–106|isbn= 1-85391-186-0}} Their diet consists mainly of insects and other invertebrates. Larger species also take lizards and even small mammals. Most species are sedentary, but the Eurasian stone-curlew is a summer migrant in the temperate European part of its range, wintering in Africa.
Species
The earliest definitive stone-curlew is Genucrassum bransatensis from the Late Oligocene of France.{{Cite journal|author1=Vanesa L. De Pietri |author2=R.
