Notes

  • S3560 - 656: A count of 6,540 in the LCB in 1999 makes the former estimate of B/C seem too low.
  • T2178 - Increasing in Southern Africa (298). Has declined sharply in Madagascar over >30 years due to disruption and predation by man (472, 400).
  • T5341 - 920. Since the mid 1980?s, numbers are locally increasing.
  • T2177 - 920. Since the mid 1980’s, numbers are locally increasing.
  • T6686 - Has increased in the Lake Chad Basin between 1980s and 2008 (Trolliet in list, 2011), but there is insufficient data to draw conclusions for the whole population.
