Correction: High Resolution Spatial Mapping of Human Footprint across Antarctica and Its Implications for the Strategic Conservation of Avifauna

Table 3 contains an error in the estimation of the number of global population (pairs) of Chinstrap penguins (Pygoscelis antarctica) within ASPAs. It should read as 5–10%. Please see the corrected Table 3 here.

Table 3. Percentage¹ of the estimated global population of Antarctic bird species found within IBAs also designated as Antarctic Specially Protected Areas (based upon data contained in [3]: Harris et al, 2015).

● Percentage value is within the range indicated

○ Global bird populations (pairs) are not accurately known for all species (see column 4). Where the possible percentage population within ASPAs may be within two percentage ranges, both are indicated with this symbol.

¹ Percentages are likely to be conservative estimates, as data for each species within all ASPAs were not available. This may be particularly true for species with colonies found in remote locations and not subject to regular counts. Values are derived from counts of bird pairs rather than individuals (see [3]: Harris et al., 2015, pg. 4). Smaller numbers or lower concentrations of bird species are also likely to breed within other ASPAs not designated as IBAs.

² Species recorded and possibly breeding within at least one ASPA, but numbers are not available.
