'' Rhinoptilus '' is a genus of coursers, a group of wading birds. There are four species, which breed in Africa and South Asia. They have long legs, short wings and long pointed bills which curve downwards. Although classed as waders, they inhabit deserts and similar arid regions. Like the pratincoles, the coursers are found in warmer parts of the Old World. They hunt insects by sight, pursuing them on foot.〔Hayman, Marchant and Prater (1986) ''Shorebirds'' ISBN 0-395-37903-2〕 Species in the genus have earlier been placed under other genus names including ''Macrotarsius'' (Blyth), ''Chalcopterus'' (Reich.) and ''Hemerodromus'' (Heuglin). Some characteristics of this largely African genus include a bill that is shorter and stouter than in ''Cursorius'', the orbits are feathered and the 2nd and 3rd primaries nearly equal and the longest. The tarsus is long and scutellate, the feet are short and the outer toe is joined by partial webbing.〔Jerdon, T. C. (1864) The Birds of India. Volume 3. p. 628〕 Their 2–3 eggs are laid on the ground. ==Species in taxonomic order== *Double-banded courser ''Rhinoptilus africanus'' *Three-banded courser ''Rhinoptilus cinctus'' *Bronze-winged courser or Violet-tipped courser, ''Rhinoptilus chalcopterus'' *Jerdon's courser ''Rhinoptilus bitorquatus'' 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Rhinoptilus」の詳細全文を読む スポンサード リンク
