Chough. I took a clutch of egj?s this year in Sark on April 30th, they 

 appeared to have been sat on about a week or ten days. The same pair 

 laid again and hatched young. I saw no others breeding in Sark and do 

 not understand why they are not more numerous. I am inclined to 

 think the Jackdaws, which are more plentiful, may drive them away to 

 safer breeding places. 



Common Tern. Breeds in considerable colonies on the Buron Rocks and 

 the Moie de la Bretagne off S^rk. In these stations every nest contained 

 eggs on June 14. On May •25th, I found several nests on the Humps, but 

 only two of them had a single egg each. 



Shag. At the end of April all the eggs I found were hard set, but I took 

 two fresh ones the first week in June, which must have been the second 

 laying.
