Senegal Thick-Knees are closely related to Eurasian Stone Curlews, as evidenced by their very similar appearance. The main differences are that Senegal Thick-knees have a slightly longer, stouter bill with more black than the Stone Curlew, no black-bordered white wing-bar, and a slightly plainer outer tail. They are more closely tied to water, preferring similar habitats to Eurasian Stone Curlews but always near rivers, lakes, mangroves or irrigated fields. Senegal Thick-knees are resident in Egypt and also much of central sub-Saharan Africa.
