A great dolphin swimming trip this morning! Our clients swam amongst a feeding frenzy of dolphins, birds and tuna. The Cory's shearwaters and great shearwaters are proficient divers and are great at diving down deep to feed on fish like mackerel and sardines which the dolphins corral into tight bait balls. This feeding association is well established between the dolphins and cagarros (as the Cory's shearwaters are known here in the Azores), and sometimes we are lucky enough to find ourselves right in the middle of it with a mask and snorkel! The incredible diving capacity of these shearwaters was captured by the BBC during the filming of Blue Planet and can look something like this.
