Grant Sherman's surveys of the seabird cliffs on the island include:
"1245 Guillemots on my survey ledges this morning. A lot of birds sitting hunchbacked on the St Philip's Stone sites (presumably sitting on eggs). Not as many on the Jenny's Cove sites - however I did get a photo of this egg. 13 Puffins on the land and 5 on the water at St Philip's Stone. 35 Puffins on the land and at least 10 on the water at Jenny's Cove around 4 or 5 hundred Razorbills but I didn't do a proper count. Some Kittiwakes were collecting grass and turf for nest material. "
