2011 turned out to be a poor year for fulmars on Eynhallow. Our colony census on 20th May recorded 91 occupied nests but when we returned on the 9th July, only 24 nests were still occupied. Once into the chick rearing period, birds seemed to fare slightly better, but with only 15 fledglings, this still meant that this year’s overall reproductive success was only 16%. Ten of these chicks were ringed by Ewan Edwards during our final visit of the season in mid-August.
