Portrait of a Lava gull on Genovesa ('Tower'). The lava gull is one of the world's rarest gulls. There are only 450-600 pairs on earth. But - they are all found in the Galapagos, so on these islands, it is not uncommon! Unfortunately most of the specimens are found in the three ports which are not included in the national park, so, even though the species seems to be multiplying, it is considered 'vulnerable'.
