PLATE I 

 BLACK GUILLEMOT. Uria grylle 



June \$th, 1896. This nest was under a huge block of rock on one of the 

 Garvelloch Islands off the coast of Mull. The eggs were quite visible from 

 the outside, as appears in the Plate. When I came up the little bird was 

 sitting on the eggs with her back to me ; on my appearance she hurried off 

 into the darkness and flew away from the other side of the rock, having no 

 doubt escaped by the back entrance. 



The eggs were very highly incubated, and under a stone not far off I 

 found two little black downy young ones, which must have been hatched some 

 time. One or two fragments of tiny herrings were lying beneath the stone, 

 and we saw one of the old birds fly into the hole with another fish held 

 crosswise in its bill, soon after we moved from the spot. 



Another nest on the same island was quite inaccessible. It was placed in 

 a vertical crack in the rocks about four inches wide and perhaps eight feet 

 deep ; we could just make out the two eggs in the darkness.
