This is a scarce, shy bird, difficult to approach. Sometimes called the Great Stone-Curlew, this large wader prefers rocky embankments along rivers. It has declined over much of its range and is currently classified as "Near Threatened." They prey mostly on crabs, but one case of a nearly intact Indian Monitor Lizard (Varanus bengalensis) with a total length of over 8" has been documented being fed to a chick.
