The penguins approached the stones and took care in choosing one they liked. Once they had a pebble securely in tow, the penguin took off, waddling or swimming over to their chosen mate and delivering the decorated treasure.

According to oceana.org, male penguins find the smoothest pebble to give to a female as a gift. If she likes the offering, she'll place it in the nest, showing that the two are working to build together. The penguin couple then continue building their nest in preparation for the eggs.

The Detroit Zoo is home to The Polk Penguin Conservation Center, a 33,000-square-foot facility with a 326,000-gallon, 25-foot-deep aquatic area where visitors can watch as the penguins explore their habitat.
