Wallpaper Wednesdays: Atlantic Puffins
When it's not breeding season, Atlantic puffins are typically alone. They spend fall and winter diving and foraging underwater or resting on waves in the deep, open ocean, far from land.

Atlantic puffins' breeding season lasts from late spring through summer. Known to form long-term monogamous bonds, they tend to return to the same nest with the same mate year after year. Females lay one egg at a time, and her male partner shares incubation duties. Both parents are also equally involved in caring for their hatchling, called a puffling.
