After seeing many blue-footed boobies, noddy terns, finches, and other birds the last bird I saw yesterday was this Galapagos duck swimming in a salt-pan as we walked. We were on our way to one of many amazing deep clefts in the shoreline where salt and a bit of fresh water mix. This island was formed by volcanic activity over the hot spot where the magma comes up, but that was very long ago, and since then earthquakes have caused many rifts and uplifts.
