The bronze-winged courser or violet-tipped courser (Rhinoptilus chalcopterus) is a species of bird in the family Glareolidae. It is found throughout Sub-Saharan Africa. Large courser with dark brown upperparts and a white belly. In flight, shows a dark upperwing and a black-and-white underwing. Found in savannah and woodland, including miombo and Guinea savanna. A nocturnal species, it spends the day roosting under a thick bush. Calls at night with a haunting, slurred “chee-yaaaa-oo.” This is the courser that is most similar to a lapwing, but its shape is different: taller and with longer legs, and the details of the head and breast pattern don’t match those of any lapwing.
