Antarctic prion

Left the SE tip of South Georgia last night and headed SW to Elephant Island, almost reversing Shackleton's famous route. We will spent 2 days at sea. Winds slight but a rainy day with poor visibility , so didn't see as much as previous days. A school about 50 fin whales and this little fella, an Antarctic Prion I'm reliably informed.  There's lots of them constantly flitting around the boat.
