PhD 2005: Patterns of primary moult in the weavers, Ploceidae [PDF full-thesis 5.2 MB]

 

 

 

 

 

Qualifications and experience

Dieter studied Physics at UCT, obtaining a BSc in 1987 and BSc(Hons) in 1988 (radioactivity in mussels). Dieter started bird-ringing while studying at UCT. Dieter worked at the CSIR in Pretoria from 1990 to 1997 in the radiocarbon dating laboratory. While working he obtained an MSc in Physics (radioactive dating of Kuiseb calcretes in Namibia). He served on the committee of the Northern Transvaal Ornithological Society (now Pretoria Bird Club) during 1996 and 1997. In 1998 Dieter took up the post of Ringing Coordinator with SAFRING. He completed a PhD in 2005 on the primary moult patterns of many southern African weavers - see link above to the thesis.

Research interests

Dieter's interest in birds began with Southern Masked Weavers while he was in high school. His interest has expanded to include all the weaverbirds, on which he is compiling a bibliography. He studied the primary moult patterns of many southern African weavers (see PhD above). An exciting project which anyone can take part in, is PHOWN (Photos of Weaver Nests) - take a photo of a weaver colony, with details of date, species, coordinates, and nest count, to help Dieter study variation in colony sizes of weavers.
