To attract and keep mates, penguins are very particular about which twigs and stones they use to construct nests. This can lead to swiping choice items from other penguins, making guarding nests nearly as important as building them. Materials are plentiful at Shedd, and yet this natural foraging behavior persists. | Shedd Aquarium | Facebook
