Behaviour of Rufous-cheeked Nightjar Caprimulgus rufigena, a summer visitor to southern Africa, was studied in Zimbabwe during two breeding seasons, using radiotracking to follow individuals and locate nests. Males defend territories by regular singing at potential nest sites. Females and other males are attracted to these sites; intruding males are challenged vocally on the ground and during aerial chases; females test possible nest spots, while the resident male watches, sings and/ or follows and displays. No nest is prepared; the eggs, usually two, are laid directly onto the ground. Egg losses are high but replacement clutches are sometimes laid. Females incubate by day, males at night; both may feed or roost outside the territory. Flying insects are caught in short flights from the ground.
