| Abstract | Abstract Copulation patterns in the osprey, based on an exceptionally complete data set, are described. Ospreys copulated frequently, on average 160 times per cluth (range: 88–338), but only 39% of copulations resulted in cloacal contact. Pairs averaged 59 successful copulations per clutch, starting 14 days before, and peaking in the few days before the start of egg laying. Copulation occurred most often in the early morning, at the same time as egg laying. Female ospreys spent almost all their time (more than 95%) at the nest and were fed there by the male. There was no association between courtship feeding and copulation, and hence no evidence that females traded copulations for food. Males maximized the time they spent at the nest with the female just prior to and during egg laying. Extra-pair courtship and copulation occurred and the results support the idea that in species with substantial paternal investment males should also invest heavily in paternity assurance. Male ospreys protect their paternity by frequent copulation and by maximizing their time with the female when she is most fertile. |
