It was formerly regarded as a subspecies of the Masked Booby but the Nazca Booby is now recognized as a separate species. The Nazca Booby co-occurs with the Masked Booby on Clipperton Island, where they may rarely hybridize.

The male Nazcas then wait for the females to show and perform the sky point too. In females however, this action will indicate that they want to be impressed by the males.

Once the two sides have agreed, males begin to offer gifts to the females. These gifts will be ignored at first, just as if the female would be saying: ‘I do not know you well enough yet’, however, soon she will accept the gift. As soon as that happens, it is only a matter of time for them to mate.

Mating does not last as long as courtship, it happens extremely quickly. The dance itself has the purpose of creating a little depression in the ground where the eggs will eventually be laid.
