Abstract:Summary Anthony, A. J. & Sherry, B. Y. 1980. Openbill Storks breeding in the southeastern lowveld of Zimbabwe Rhodesia. Ostrich 51:1-6. Openbill Storks Anastomus lamelligerus bred in the Gonarezhou National Park at Tam-boharta pan between January and June 1974 and again in 1975. Two breeding cycles occurred during the 1974 season. The storks nested in a mixed heronry in Acacia albida trees which were at the time rooted in a flooded alluvial pan. In 1974, 65 of 165 nests in the colony belonged to Openbills and in 1975, 78 of 130 nests belonged to Openbills. Successful breeding activity appeared to be associated with excessive rains, resulting in submerged trees in which to nest and abundant snails on which to feed. Clutch size was three to four eggs and hatching was markedly asynchronous. The only food item regurgitated by nestlings was the soft parts of the snail Lanistes ovum which abounded in the swampy areas near the heronry.Summary Anthony, A. J. & Sherry, B. Y. 1980.
