Data from: Phylogeography, population structure, and species delimitation in rockhopper penguins (Eudyptes chrysocome and Eudyptes moseleyi)
Rockhopper penguins are delimited as two species, the northern rockhopper (Eudyptes moseleyi) and the southern rockhopper (E. chrysocome), with the latter comprising two subspecies, the western rockhopper (E. c. chrysocome) and the eastern rockhopper (E. c. filholi). We conducted a phylogeographic s...
