The Senegal thick-knee (''Burhinus senegalensis'') is a stone-curlew, a group of waders in the family Burhinidae. It is a resident breeder in Africa between the Sahara and the equator, and in the Nile valley. Senegal thick-knees are medium-large waders with strong black and yellow black bills, large yellow eyes — which give them a reptilian appearance — and cryptic plumage. The scientific name refers to the prominent joints in the long yellow or greenish legs. They are similar but slightly smaller than the Eurasian stone-curlew, which winters in Africa. The long dark bill, single black bar on the folded wing, and darker cheek stripe are distinctions from the European species. Senegal thick-knee is striking in flight, with a broad white wing bar. This species has a preference for dry open habitats with some bare ground, preferably near water. It lays two blotchy light brown eggs on a ground scrape. It is most active at dawn and dusk. The song is a loud ''pi-pi-pi-pi-pi-pi-pi''. Food is insects, crustaceans and other invertebrates. It will also take other small prey. ==References== 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「Senegal thick-knee」の詳細全文を読む スポンサード リンク
