'218 BIRDS OF GUERNSEY. 



before, and the egg was one which had been sat 

 on and hatched, and might therefore have been one 

 of the previous jesiv ; and the same, possibly, 

 might have been the case with Col. L'Estrange's 

 two addled eggs. It appears, however, to be rather 

 irregular in its breeding habits, nesting from the 

 end of May to July or August. In Burhou the 

 Storm Petrel bred mostly in holes in the soft black 

 mould, which was also partly occupied by Puffins 

 and Kal)bits, but occasionally under large stones 

 and rocks. We did not lind any breeding on the 

 islands to the north of Herm, but they may do so 

 occasionally, in which case their eggs would 

 probably be mostly placed under large rocks and 

 stones, where the Puffins find safety from the 

 attacks of the various egg-stealers. At other times 

 of year than the breeding-season, the Storm Petrel 

 can only be considered an occasional storm-driven 

 visitant to the Islands. 



It is included in Professor Ansted's list, and 

 marked as occurring in Alderney,. Sark, Jethou, 

 and Herm. 



AYith this bird ends my list of the Birds of 

 Guernsey and the neighbouring Islands. It con- 

 tains notices of only 176 birds, 21 less than 

 Professor Ansted's list, which contains 197 ; but it 

 seems to me very doubtful whether many of these 

 21 species have occurred in the Islands. I can 

 find no other evidence of their having done so
