Yesterday we ringed over 260 common murres and about 60 razorbills in a large colony on an island in the Baltic Sea. It is amazing to see the large numbers of birds on the island. Unfortunately these large colonies are becoming rarer, often do to us... climate change, introduction of invasive alien predators, oil spills, you name it. That is one of the reasons research and monomtoring is needed. We need to know what is happening to seabird colonies in good time so we can at least try and do something about the decrease of species. Luckily the colony we visited seems to be doing just fine, for now...
