Many thanks to Jack McKee for sharing his fantastic pictures of gentoo and macaroni penguins. To fully appreciate the stunning images, please click on each picture to the full-sized version. These pictures clearly show the amazing nests these cold-climate birds build.
Both Gentoo and Macaroni penguins build their nests from smooth pebbles. Once they have chosen a mate and gone through the courtship process, then construction of a nest begins. And construction is a good way to describe it. In the wild a medium size Gentoo nest contains an average of 1700 pebbles. Penguins know how to pick out the very best pebbles or stones and are not above stealing “the perfect pebble” from another nest. Once the nest is complete, eggs will be laid and in a few weeks chicks will be hatching.
