We're up and about before breakfast this morning, exploring a visitor site on Floreana Island called Punta Cormorant. We land on an olivine sand beach and walk along a trail to a beach of incredibly fine, white, coralline sand. This is a favourite nesting site of green sea turtles and we see many turtles in the water this morning, including one female surrounded by attentive males! Along the trail we skirt a large salt pond that is occasionally home to flamingoes and pintails. After breakfast we reposition our ship to the nearby islet of Champion. Here there is a small population of the elusive Floreana mockingbird, now extinct from the mainland due to cats and other introduced species. We circumnavigate Champion in our pangas and we manage to spot some mockingbirds! This is a good result considering there are only about 40 pairs on the islet. After lunch we lift anchor again and visit Post Office Bay. Here there is a barrel, still used for an old mail swap tradition going back to whaling days. The idea is to take these by hand and deliver them when we get back - no stamp needed. We sort through the post cards and letters already in the barrel to find any addresses that are near our homes. We find a few cards to deliver (but interestingly no postcards from our guests last month are still here ..... perhaps they are already on the way home to the UK!). We pop our own cards in the barrel and hope these may get delivered soon. Time will tell.
