Swans choose their mate at a young age, when they are only a couple of years old. There is a complex courtship display when swans face each other, during which they dip and turn their heads or spread and raise their wings. They also “kiss bills,” which forms the famous heart shape with their necks. Many swans are monogamous and mate for life, but some pairs are not. If the swan couple has trouble reproducing, they “divorce” and find new partners. ( Source)

These famous blue-footed birds do a dance when it’s time to mate. The male blue-footed booby shows off his webbed feet to a potential female partner. The more pigmented his feet are, the better his chances are at mating with her. The vivid color indicates his ability to acquire food, so the brighter the better. He displays his feet in an elaborate high-stepping walk. His dance also includes a wing display and an upwards beak tilt, which the female hopefully reciprocates. Once she chooses a mate, the two form a monogamous pair and reproduce. ( Source)
