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. 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.
