Galapagos Shearwaters take an afternoon sail aboard Peregrine.
We saw hundreds of Olive Ridley Sea Turtles and many times Black terns were aboard for a ride. I only saw boobies on them twice. One day, I counted 27 turtles in less the 10 minutes. I don't know if they were on the way to lay eggs or if they had just done so or what was happening, but we've never encountered so many in one place before. This was off the coast of El Salvador.
