Shearwaters are truly amazing birds, rarely coming to land except to breed. It seems they can even shut down part of their brain when flying allowing them to sleep all the while using the thermals above the waves to glide forever. However, they do feed from the ocean, and as can see below Audubon Shearwaters tend to hang out near sargassum. In the below photo this Audubon's Shearwater was flipping sargassum in the air probably trying to dislodge crabs and other morsels. Or dare I say it.... maybe he/she was playing.
