Behaviour of Kingfishers (Halcyon sancta vagans) was studied at three nests in Canterbury. Courtship feeding was observed. Chicks were fed by both parents, predominantly on lizards, crabs and insects. No difference was found in the proportion of prey sizes fed to chicks of different ages ((2=0.02, p>0.05). Chicks were fed about every 20 min in the first week, the rate increasing to every 10 min in the latter stages of nesting. Kingfishers were aggressive during nesting and attacked a wide variety of species as well as other Kingfishers. Mortality during nesting of adult Kingfishers was heavy in suburban habitats.
