11 January 2017
Dawie de Swardt (Ornithology Department) and Jan Andries Neethling (Arachnology Department) attended the 13th Kimberley Biodiversity Research Symposium at the Mcgregor Museum in Kimberley. This symposium is presented annually by the McGregor Museum, Northern Cape Department of Environment and Nature Conservation, SANParks (Kimberley) and the South African Environmental Observation Network (SAEON). Dawie gave a presentation on his research on African Rock Pipits: African Rock Pipits from work done at Tswalu kalahari Reserve and Grobleshoop area.

Bird ringing expedition in Lydenburg

11 January 2017
In February Dawie de Swardt undertook a bird-ringing trip to Lydenburg as part of his annual visit to the study site of the Gurney Sugarbird project. This year he was joined by a group of bird ringers from BirdLife Northern Gauteng, Pretoria, who were interested in the project. They assisted in capturing and ringing sugarbirds and other species and obtaining recapture data. During this visit 19 sugarbirds were captured and blood and feather samples taken. Bird ringing was also carried out in the nearby Gustav Klingbiel Nature Reserve outside Lydenburg where more than 200 birds were captured. Dawie also presented a talk and a bird-ringing demonstration to members of the Escarpment Bird Club at Paardeplaats, Lydenburg. His presentation, Gurney's Sugarbirds in the Lydenburg area – three decades of dedicated research,gave an overview of this long term project.

Training opportunities

14 December 2016
Mmatjie Mashao, technical assistant in ornithology at the Durban Natural Science Museum, visited the Museum during November 2016 to be trained by Dawie de Swardt (ornithologist) and Lots Morapedi (preparator) in preparing study skins as well as curation techniques for the storage of study skin, skeleton and tissue sample collections.

Senior Museum Scientist and Head of Department

Dawid H. de Swardt MSc dawie@nasmus.co.za

Dawie joined the Ornithology Department in 1988 assisting Dr. Roy Earlé with his research on South African Cliff Swallows, as well as other swallow and swift species. Dawie was also involved in a long-term project on Gurney’s Sugarbirds in eastern Mpumalanga and it was not long before a study was also undertaken to investigate the movements of Malachite Sunbirds in the Free State. Other research projects include a behavioural study on the Northern Black Korhaan, behaviour and vocalization of the African Rock Pipit and assisting Rick Nuttall with his projects on cisticolas, white-eyes and estrildid finches. Currently a project on the Karoo- and Drakensberg prinias in the Free State and adjacent areas is undertaken, concentrating on areas of possible overlap. Dawie has a National Diploma in Nature Conservation (1987) and National High Diploma (Foresty): Conservation from Saasveld, George (now Nelson Mandela Metropolitan Univeristy, George Campus, Saasveld) (1995). His thesis on Gurney’s Sugarbirds “Aspects of the behaviour and ecology of Gurney’s Sugarbird Promerops gurneyi Verreaux, 1871 in Protea woodland, South Africa” earned him an MSc (1998). Bird ringing also forms an integral part of research projects and more than 13 000 birds have been ringed since 1987. Dawie has also been involved in the first bird atlas project (1988 -1992) and currently in the SABAP2 project. He is also responsible for collection and curation of the bird collection, representing mostly Free State birds.

Zingisile Mbo - Intern Ornithology Department

Zingisile recently joined the Ornithology Department as an intern from 1 July 2023. His duties include assisting Dawie de Swardt and Lotz Morapedi, and Michael Bates and Oladayo Idris in the Ornithology and Animal and plant Systematics Departments respectively, with skin and skeleton preparation, maintenance of specimens in the collection room and herbarium and image capturing of specimens.

Preparator

Lotz Morapedi

Lotz is, since 1983, a General Assistant in the Ornithology Department. He is mainly responsible for the preparation of research specimens that involves the preparation of bird specimens as study skins as well as skeletal specimens and the subsequent curation of it. He also assists with research projects such as bird ringing and collecting.

• General bird collecting to expand the Ornithological collections and bird ringing as part of the Department's curation and reserach activities.
• Study on Gurney's Sugarbird Promerops gurneyi isolated island populations in Limpopo Province and adjacent areas and their genetics based on blood sampling from birds.
• Ad hoc project on Secretarybird breeding activities and nest monitoring in the Bloemfontein area. In collaboration with BirdLife South Africa to fit sattelite transmitters to nestlings if available.
