Table 2: Estimates of numbers of African Penguin (pairs) breeding in southern Africa in five different periods between 1956 and 2020–
2022 (sources of information are given). Also shown are the most recent values obtained for each site. The decade of observation of the
most recent value is colour-coded and the percentage contribution of values from different decades to the sum of the most recent values is
indicated. Sites having ≥ 5 pairs that qualify as regional IBAs are highlighted in grey, as are ‘super sites’ that hold ≥ 1% of the most recent
population estimate. The locality used in De Hoop Nature Reserve was Witklippunt
