Two of the five births in Area 1 surprised us in that they did not from dolphins that had yet been identified as adult females. On October 1st Batman and Button, two dolphins that had previously been categorized as sub-adults, showed up with recently born calves in tow. This is exciting for a couple reasons: we can now identify their gender (for a dolphin, showing up with a baby is a dead give-away in this respect) and, with the possible exception of Darwina in 2006, these are the first births in our study area that we can be certain are first calves for these mothers. Statistically first time births are less likely to survive the first year, but to date, Robin and Zipper appear to be doing fine. As calving season in this Area extends into the first months of winter, there may yet be more surprises from the sub-adults of Area 1.
