What an odd exhibit! Why is the Inca tern there? The hexagonal columns of rock look like the basalt formations seen in certain cliffs, such as the Giant's Causeway in Northern Ireland - but basalt is dark grey, not brick-red
@gentle lemur It is based on cliffs in the Faroes Islands, but I don't know whether they are red... The Inca terns probably replace native terns, which are hard to get in captivity...
