Study of Birds


The Ornithology Department was established in the early 1970s, with the appointment of Dr Tibor Farkas (1973-1986). The organization of material on display, much of which was exotic in origin, was the primary objective at this time.

Active collection of material began in the mid 1970s, but a lack of resources prevented the addition of new material to the collection between 1979 and 1982.

During Dr Roy Earlé’s term as Head of Department (1983-1990), the main objective was to resurrect active collection, focussing on birds representative of the Free State. The organization of the collection however meant its rationalization to about 500 study skins, as a result of deterioration of many specimens. There are currently more than 5000 skins in the collection.

A skeleton collection, started in 1983, grew rapidly and currently contains more than 2760 specimens. This collection is also widely used by palaeontologists and also for owl diet studies and other identifications. The aim of the Department is to built a representative skin collection and active collecting is still carried out in various parts of the Free State which is a  ongoing project.  Lots Morapedi was appointed as preparator in 1983 and is responsible for the preparation of the skeletal and skin specimens in the collection.

Collection of avian ecto-parasites and avian blood parasites began in 1987. The alcohol collection was started in September 1988. A tissue sample collection was started in 2011. Samples were also donated by visiting researchers from the University of New Mexico, the Natural History Museum of Paris, and the University of California based on Ornithology Department assistance with their field trips in the Free State.

Management of the Departmental collection was the responsibility of Ben Bester (1984-1985), Hester du Toit (1984-1992), Kotie Herholdt (1985-1988), Mariana de Wet (1986-1989), and Dawie de Swardt (1988 to present).

Rick Nuttall was Head of Department from 1991-2003, whereafter Dawie de Swardt was appointed to this position.

Research – past and present

Research in the Department has focused on the taxonomy of the Turdidae, on bird communities of various vegetation types, and on the distribution of species in the Free State Province (Tibor Farkas). Roy Earlé studied the biology of a number of species and groups of birds, including swallows (Hirundinidae), White-browed Sparrow-weaver Plocepasser mahali, Ant-eating Chat Myrmecocichla formicivora, Ground Woodpecker Geocolaptes olivaceus, House Passer domesticus and Cape Sparrow P. melanurus, as well as aerial-feeding bird communities in the forested north-eastern parts of South Africa. In collaboration with other researchers, Roy began to identify and describe avian blood parasites of South African birds. Together with Professor Nick Grobler (University of the Free State), he also produced the first Atlas of Bird Distribution in the Orange Free State, published in 1987.

Although employed as Collections Manager, Kotie Herholdt also carried out research, focusing mainly on the distribution patterns of Ludwig’s Neotis ludwigii and Denham’s Bustard N. denhami, breeding biology of the Ant-eating Chat Myrmecocichla formicivora, and of Little Swifts Apus affinis in urban areas. Dawie de Swardt, as research assistant before appointed as HOD, also assists with Roy Earle’s and Rick Nuttall’s projects in the Free State. Rick Nuttall’s research involves Zosterops (white-eye) systematics, behavioural ecology of estrildid finches (Estrildidae), systematics of various Cisticola species and moult and migration of Barn Swallows Hirundo rustica; the latter also involves collaboration with other swallow researchers, both locally and internationally.

Dawie de Swardt, who is the current HOD of Ornithology Department, studied the behaviour of the Northern Black Korhaan Eupodotis afraoides, the biology, movements and biometrics of Gurney’s Sugarbird Promerops gurneyi and Malachite Sunbirds Nectarinia famosa.  Dawie also completed his Msc degree on Gurneys Sugarbird in 2008 and was invited by the Editors of the Handbook Birds of the World series to write the Promeropidae family text for volume 16 of the series.  Other projects includes the behaviour (and song dialects between different populations) of the poorly-known African Rock Pipit Anthus crenatus and the taxonomical relationships of Karoo Prinia maculosa and Drakensberg Prinias P. hypoxantha in the Free State and adjacent areas. In collaboration with Dr Raurie Bowie (University of California, Berkeley, USA) blood samples for DNA analysis are collected from both ringed birds and collected specimens.

Current project of the Department includes general bird ringing studies and to build a representative collection of study skin material of Free State birds.  Bird ringing studies are also carried out at the Florisbad Research station on the Rufouseared Warblers Malcorus pectoralis and other bird species.  A continuation of the previous Gurney’s Sugarbird project is currently in the Soutpansberg and Haenertsburg areas of Limpopo Province to study this sugarbird species which occur in isolated islands of protea woodland in hilly areas surrounded by plantations and grasslands.  Also in collaboration with the University of Pretoria, blood samples of the sugarbirds were also collected for genetic diversity research projects.

Bird ringing expedition in Lydenburg

Bird ringing expedition to 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.

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.
