During the course of two years of bird population counts at Sandvis (previously also known as Sandwich Harbour) from July 1970 to June 1972 it was possible to compile a systematic list of the species. In addition, confirmed sightings made by visitors to the area since 1968 have been included as well as revious records by rozesky and Dixon over a eriod 1959-1970. To date the number of species recorded is 113 and represents an exceptionaIly wide taxonomic variety when the isolated nature of the area is taken into account.
Fourty-two adult elephant (22 males and 20 females) were captured in the Etosha National Park with etorphine (M99 Reckitt). The utilization of a helicopter resulted in the capture of 41 elephant in 7 days. The mean immobilization time was 14 min 56 seconds. The capture operation was successful and only one death was recorded.
The successful application of the plastic boma technique for the capture of more than 80 eland, Taurotragus oryx oryx (PaIIas, 17661, with the aid of a light, fixed-wing aircraft and a helicopter is descriptionbed. No animals succumbed to capture myopathy despite herding over long distances. Following a 3 month captivity period in the bomas, during which 21 calves were born, the eland were successfully transported 250 km by road in communal crates. Adult bulls had to be transported separately and were sedated with haloperidol (R1,625 - Serenace).
Between 1970 and 1972 forty three black rhinoceroses Diceros bicornis Linn., were darted from a helicopter and transferred to the Etosha National Park, where they have become well established and now constitute a viable population. Using an etorphine/azaperone combination, a mean immobilisation time of 8 min 22 s was obtained. A multi-lift system fitted to the transport vehicle facilitated the loading of rhinos in difficult terrain.
