THE CHARACTERS OF A NEW RACE OF Alcedo semitorquata Swainson FROM THE LOW COUNTRY OF PORTUGUESE EAST AFRICA

Arkell, G. B. F. 1979. Aspects of the feeding and breeding biology of the Giant Kingfisher. Ostrich 50:176-181.

Giant Kingfishers Megaceryle maxima were studied during 1972–1975 on the Eerste and Blaauwklip Rivers near Stellenbosch (33 53s; 18 50E), South Africa. Nest record cards of the Southern African Ornithological Society were examined for dimensions of the nest, nest lining, clutch-size and brood-size. The feeding rate of nestlings was determined from observations at the nest. Two adults, comprising a pair of breeding birds, and a fledgling wert equipped with breast-mounted miniature radio transmitter packages to monitor the birds activity and home range. Cape River Crabs Potamon perlatus apparently were the main prey of the kingfishers. A correlation was found between the activity patterns of kingfishers and of crabs, which peaked in the mornings and evenings.
