Research Projects in Parrot Biology


Environmental Physiology of African Parrots (Stephen Burton: M.Sc student)

The ecophysiology (metabolic rate, thermal biology, and water turnover) of lovebirds from different habitats/environments eg. semi-arid, woodland savanna and forest Several species are available in captivity here, but there would be a need for some field work to record ambient temperatures, and for isotopic dilution studies to determine field rates of metabolism to calibrate the lab studies. State of the art equipment is available and being expanded. (With Prof Downs

 

Vocalisations of African Lovebirds (Dr. S. Taylor, Craig Symes, Prof. Downs)

The work we plan on vocalizations relates to (a) degree of sociality (white eye-ring species versus non-white eye-ring species), (b) systematics, do the more closely-related species have the most similar calls?, and (c) do the calls of species in similarly structured habitats eg. closed forest or semi-arid (open) environments show convergence? (b) and (c) are alternative explanations.  In addition, we will continue investigations of high frequency sound production in parrots, and its function in social communication, which is new, exciting and cutting edge.  (With Dr. Dempster).

 

Parrot Diets, Nutrition and Breeding Success (Luthando Maphasa:  Ph.D student)

We have run some diet experiments on lovebirds over the last two years. Looking at how nutrition (protein and supplements etc., but also age and breeding experience) affects breeding success (eggs laid, hatched; growth rate and fledging of chicks).  There is a lot more scope for further experimentation of academic and commercial importance.  (With David Dennison and Mark Brown).

 

Autecology, Trade and Conservation Biology of the Rosy-faced Lovebird in Namibia and the Lilian's Lovebird in Malawi (Henry Ndithia, M.Sc student; Lawrence Luhanga, M.Sc student)

A detailed field research project is necessary focusing on (a) distribution and abundance, (b) breeding biology, (c) feeding ecology, (d) how changes in c (use of manioc and rice) affect b, (e) potential for formal (legal) trade to benefit impoverished local people.

A similar study is required on the virtually unknown Yellow-headed Parrot in the Yellowwood-Juniper Forest of Ethiopia.

 

Movements of African Parrots using Radiotelemetry (Henry Ndithia, M.Sc student; Stephen Boyes, Ph.D student)

We know little about the movements of parrots in relation to (a) the phenology and availability of food plants, (b) habitat fragmentation, and (c) population structure.  This could be done with one or more species, Cape Parrots, Brown-headed Parrots, Ruppell's Parrots, Brown-necked Parrots or Black-cheeked Lovebirds.  (With Illaria Carranza, and doctoral students).

 

Autecology of the common Meyer's Parrot in South Africa (Stephen Boyes: Ph.D student)

Having studied several rare and endangered species of parrots we need to study a common species with a wide distribution with reference to (a) status, distribution and habitat preferences, (b) feeding and breeding biology, (c) its ecological success re. niche dimensions and (d) comparative biology of other members of its genus.

 

Molecular Systematics of African Parrots (Planned)

Following collaborative research on the Cape Parrot group, and recent published work on lovebirds, the most important focus would be the different forms of the African Grey, which is very important re. controlling trade, ie. source and sink populations; where are the birds laundered? This would attract funds from international groups like Birdlife and WWF (IUCN), and probably WPT, ABC and Loro Parque. The American AFA and their Parrot Society are eager to resolve problems of identification of the three forms of Jardine?s (Red-fronted) Parrot. (With Dr T. Taylor and P. Bloomer).
