Figures 5.1a-m. Relative abundance (ranked) of bird species at our 13 stations

For all diagrams: species wih equal scores are presented in taxonomical sequence.

§ Mistnetting for two full days (upper diagram): A graphic presentation onf the data from Table 5.7 (but numbers mistnetted per station has been standadised to “per hundred”). We have chosen to show a diagram also for Kimhandu-6 (1540 m) despite that we mistnetted only for 13.5 hours.

§ One-hectare plots (lower diagram): A graphic presentation of the data from Table 5.9.

§ Comparability of upper and lower diagrams: For a given station the “rank” of the species in order of commonness can be compared between the upper and the lower diagrams with come caution. Certain problem of methodology and data presentation are discussed in Appendix 5.12.

Abbreviations and terms:

Th. Globally Threatened

Nt: Globally Near-threatened

xx: Of restricted range but not Threatened or Near-threatened

NF: Non-forest species

AF: Aerial feeding (forest) species

Step size: Defined as the reciprocal value of the number of plots made (example: 25 plots give a step size of 25 %)
