Description:

Responses of birds to rainfall and seed abundance in the southern Karoo, South Africa.

Summary / Notes:

Resident and nomadic birds, both insectivores and granivores, were counted at 40 sites along a 200-km east–west oval transect in the southern Karoo. Total species richness averaged 30·05±5·31 (S.D.) species per site, with less than half of the species being resident, and nomads and transients making up the remainder. There was a weak correlation between the number of individuals of resident species and rainfall, but no significant correlation between number of individuals of nomadic species and rainfall. The numbers of resident insectivores were significantly correlated with the numbers of arthropods obtained in sweeps. There was no correlation overall between relative seed abundance and numbers and biomass of granivorous nomadic birds, and no correlation between the numbers of resident granivores and the numbers of seeds. The numbers of resident insectivores, resident granivores and nomadic granivores were correlated with the presence and abundance of ephemeral plants at some sites. There was a correlation between the average number of all birds at a site and the proportion of plants that were producing new growth, suggesting that the presence of new growth influences the local abundance of birds. Keywords: semi-arid, granivory, nomadic birds, shrublands.
