Nocturnal Birds

Many thick-knee species are crepuscular (kri-PUS-kyuh-lur; active at dusk) or nocturnal (active at night). The bold, black-and-white wing and tail markings that characterize thick-knees are easy to see in fading light. Because they are nocturnal, thick-knees also defend their territories using loud calls, rather than the visual postures and displays used by other bird species. Their calls are loud and carry a long distance, and thick-knees have become an important part of the folklore in parts of their range.

Several species of thick-knees are occasionally found in agricultural lands and pastures.
