Grote griel Esacus recurvirostris

An odd-looking wader with a dark mask, staring pale eyes, and a large heavy bill. Flashing black-and-white wingtips, revealed in flight, recall those of lapwings. Found on the banks of flowing rivers and lakes with rocky or sandy shores. Usually seen standing still on shore, though can be quite shy, often flushing even at a distance. No similar species in its range and habitat; Beach Thick-Knee is similar, but is found on coastal beaches, mudflats, and exposed reefs. Gives clear, high-pitched “tleeeeLIK!”, often repeated when alarmed.
