The fieldwork season for my black guillemot project started again. Yesterday we went to the island groups to have a look around and try to find some nests. There were already about 40 to 50 birds present but thus far we only found 13 nests. We were pleased to see that two of our nest boxes were occupied! A number of nests only contained 1 egg so far, which likely indicates that the black guillemots are still laying. One nest however contained two guillemot eggs and another, unidentified egg! Our guess is that this egg could be from a goosander or red-breasted merganser, but we do not know yet! Let's see what happens to that one… We will soon go out again to try and find more nests and install our cameras.
