Male and female dead ends get acquainted, begin to rub against each other, thus expressing their sympathy. By the end of spring the beaks of dead ends will change color from orange to bright red. This is a clear signal of willingness to start a family.

As a rule, new couples are engaged in settling nests themselves. But in rare cases, they can return to last year's houses or take one of the deserted ones.

Marriages for this species are characteristica lifetime. Dead ends rarely change partners. However, when the mating season is over and the kids are strong enough, the parent couple will part. Each of them will live alone until the next spring, to meet again to equip a new nest.

In most cases, the female brings one egg. Both partners are engaged in hatching, replacing each other. The incubation period is on average 40 days.

A dead father also participates in the upbringing of a chick. Parents alternately hunt, getting food for themselves, a partner and a baby.

Practically from the first days the chicks are taught to swim. It is noteworthy that in the daytime dead ends prefer to hide offspring from natural enemies in the folds of coastal rocks. For lessons on swimming, babies are taken out at night. In such a regime, the life of the children proceeds for the first month and a half. And when this time expires, the parents leave the nest, leaving already able to hunt, fly and swim the offspring alone. Such a seemingly harsh school of life is every young Atlantic impasse.
