Summary. Four pairs of Fiery-necked Nightjars Caprimulgus pectoralis, each with two young, were observed from hatching to fledging at four different localities in Zimbabwe, two pairs of C. p. fervidus in Mashonaland and two pairs of C. p. crepusculans in Manicaland. Development of the young was measured and their behaviour recorded daily, as was adult behaviour. My observations provided corrections and additions to the literature. C. p. pectoralis and C. p. fervidus remove eggshells from the nest area after hatching, but C. p. crepusculans does not. Chicks provide a feeding stimulus by grasping the adult's bill in its own. By not responding until this stimulus, the adult ensures that each chick receives its fair share of food. Chicks do not return to the nest to be fed. They move towards a calling adult, on or off the nest. The ‘wooting’ call is not a warning call, but is used by adults to summon their chicks, which respond immediately by running towards the sound. Rictal bristles appear on day 18, and are only 2 mm long on day 19, providing no protection for the eyes during the first days of flight. On days 18–19, when the middle claw is 3–4 mm long, the inner flange splits to form a comb of four teeth 1 mm deep, the start of the pectinate claw. Primaries emerge centrifugally, as in adult moult pattern, wherein primaries moult descendantly. Adults leave their territories soon after breeding, whereas chicks, which become independent at 19–23 days, remain in their natal areas.
