Divorce among Atlantic puffins seems to be less of a big deal than it is for many other bird species. Puffin partners don't see each other at all except during breeding season. Though they spend most of the year apart, they somehow manage to find each other again at the beginning of each new season and rekindle their partnership. But that's also a time of competition. Puffins have a divorce rate of about 7 to 9 percent, usually caused when a rival male takes over the nest site and the female along with it.
