PREDATION BY PIED KINGFISHERS AND WHITEBREASTED CORMORANTS ON FISH IN THE KOSI ESTUARY SYSTEM

Summary Jackson, S. 1984. Predation by Pied Kingfishers and Whitebreasted Cormorants on fish in the Kosi estuary system. Ostrich 55:113-132. Identification of otoliths from the regurgitated pellets of Pied Kingfishers Ceryle rudis and Whitebreasted Cormorants Phalacrocorax carbo from the Kosi estuary system provides information on the relative proportions of fish species in the diets of the birds. This information can be related to the feeding habits, distribution and abundance of their prey. It is also an indication of the feeding range of the birds. There is little overlap between both the size classes and the species of fish taken by the two predators. This is because of the difference in size and fishing techniques of C. rudis and P. carbo, and of differences in their feeding ranges. Competition for food between the two populations of birds studied is minimized by these differences.

MENSURAL AND MOULT DATA OF EIGHT SPECIES OF KINGFISHER FROM MOÇ AMBIQUE AND MALAŴI

Summary Hanmer, D. B. 1980. Mensural and moult data of eight species of kingfisher from Mozambique and Malawi. Ostrich 51:129-150. Wing length, weight and moult data are given for the Malachite Kingfisher Alcedo crisrata, Pygmy Kingfisher Ispidina picta, Woodland Kingfisher Halcyon senegalensis, Greyhooded Kingfisher H. leucocephala, Brownhooded Kingfisher H. albiventris, Striped Kingfisher H. chelicuti, Pied Kingfisher Ceryle rudis and Giant Kingfisher C. maxima from Mopeia (Mocambique) and Nchalo (Malaŵi). Plumage characters of immatures are given, with their probable duration, age being determined by skull pneumatization, retrapping, moult and the breeding season, for the first six species. Moulting seasons, immature age at moult, the duration of primary moult, its relation to the breeding season and the sequence of moult in remiges and rectrices are given for A. cristala and I. picta and discussed for the Halcyon kingfishers. Some data are given on habits.
