Day Twelve, March 5, Bonus day two — a trip to Islas Contreras, Montijano wind, two elusive whales, and bottlenose dolphins
Our last full day of the expedition was spent surveying the small island group to the east of Islas Secas known as Islas Contreras. On our way there (under a head wind locally known as “Montijano”) we spotted two whales traveling together, keeping a low profile. We slowly approached them as we observed them for a surfacing interval. However, we were unable to relocate them, and because we didn’t get good looks we had to record them as “species unidentified”. Nearly simultaneously, we spotted a small group of bottlenose dolphins in the area that appeared to be of the “oceanic ecotype”. These dolphins were quite large and darker in color than the coastal group.
