The fairy tern is a similar size to a hooded plover - so tiny, it would sit comfortably in the palm of your hand. They lay just two eggs, onto the beach sand. See these remarkable images from Tasmanian-based bird ecologist Dr Eric Woehler.

The dramatic-looking rockhopper penguin is characterised by its red eyes, upright yellow head feathers along a supercilium stripe and a crest of black feathers on top. They are separated into three sub-species, photographer here by ecologist Dr Eric Woehler (OAM) and located around the Antarctic and sub-Antarctic zones.

The Scandinavian mountain range, the Scandes, runs through the border between Sweden and Norway. It covers most of Norway and stretches into the north-west regions of Sweden. These mountainous areas form some of Sweden's most remarkable wilderness.
