We compared the bioacoustic structure of the alarm calls of five species of African lovebirds, genus Agapornis (A. roseicollis, A. lilianae, A. nigrigenis, A. personatus and A. fischeri). The calls were analysed for interspecific and gender differenc

An electrophoretic allozyme study of the fiscal shrike Lanius collaris, a widely distributed sub-Saharan passerine, was undertaken to investigate altitudinal variation in genetic structure within this species. It is a sedentary bird with limited disp

Aspects of the foraging behaviour along an altitudinal gradient of four subpopulations Durban, Merrivale, Estcourt and Harrismith) of colour-banded Common Fiscals (Lanius collaris) were analysed in summer and winter in South Africa. The shrike subpop
