Due to the harsh rocky environment, they cannot slide on their bellies like most penguins, so they hop to get from one place to another. What separates rockhopper penguins into subspecies is their location of reproduction and reproductive behaviors. The difference in mating signals found between the subspecies "E. chrysocome" (southern) and "E. moseleyi" (northern) seems to have occurred quickly, thus these behavioral changes are enough to isolate these taxa. Southern Rockhopper penguins are split into two
Featherless bird-riddle Featherless bird-riddle The Featherless bird-riddle is an international riddle type about a snowflake. In the nineteenth century, it attracted considerable scholarly attention because it was seen as a possible reflex of ancient Germanic riddling, arising from magical incantations. But although the language of the riddle is reminiscent of European charms, later work, particularly by Antti Aarne, showed that it occurred widely throughout Europe─particularly central Europe─and that it is therefore an international riddle type. Archer Taylor concluded that 'the equating of a snowflake to a bird and the sun to a maiden without hands is an elementary idea that cannot yield
