Had a fairly uneventful passage down from Las Palmas, with very few birds seen- just a handful of distant Cory's, a single tern sp. and what looked like a very distant immature gannet. Had a couple of Wilson's storm- petrels following the ship this afternoon though, which really brightened my mood. They hung around and put on a show for about 5 minutes before drifting off over the waves and out of view. I rattled off a few record shots before realising that I had completely forgotten how difficult it is to get shots of storm petrels with their unpredictable dancing flight- quickly changing angles and depth of field- no matter really as it is just great to see these lovely birds.
