Notes

  • S8683 - Numbers in IWC are well below the minimum of the range, whilst past estimates have taken account of count maxima in both Eastern and Southern Africa, whereas this is a trans-equatorial migrant.
  • T6667 - Past increases in Southern Africa due to dams. Limited trend information across the range.
