摘要:

The Willow Warbler is unusual in that adults undergo primary moult twice a year, a post-nuptial moult immediately before migration southwards and a moult in the winter quarters. This paper analyses primary moult data from Finland, two localities in Britain, Uganda and Southern Africa. The parameters of moult (mean starting date, synchronisation and duration) at each locality are estimated using the techniques of Underhill & Zucchini (1988 Ibis 130: 358–372). The results from each locality are compared.

摘要:

Habitat subdivision and resource partitioning of the birds of the evergreen high forest of the southern Cape were investigated. Most species utilise a wide stratal range with insectivores predominating in the lower strata and mixed-feeders and frugivores in the upper strata. Members of the respective foraging guilds used a different stratum or were separated by differences in morphology or mass, suggesting different sized prey and limited competition.

摘要:

Effects of forest plant species composition and physiognomy on bird and invertebrate communities were investigated in three discrete, relatively undisturbed forest types along a dry-wet soil moisture gradient. Discriminant function analysis produced a 100% floristic and a 78% vegetation structural discrimination between the three forest types. However, the bird communities of these different forest types were similar in species composition, and had lower densities than those encountered in superficially similar forests. Although an 81% discrimination between forest types was attained through analysis of ground surface invertebrates, measures of litter and aerial invertebrates were also of limited use as discriminators. Historical and biogeographic factors, as well as low nutritional levels in the soil and vegetation may be the causes of low bird and invertebrate density and diversity. It is concluded that floristics and vegetation structure have a minor influence on bird, and possibly on invertebrate community structure in the Knysna Forest.
