 November 30th and December 1st. 



Black-headed Gull {Larus ridihundus). 



First seen on December 2nd, when three or four flew up the 

 coast in a north-east direction ; there were scores in Mudros 

 Harbour in January. During the previous winter I noticed 

 them first on the Nile, at Cairo, about mid-December; on 

 January 17th, 1916, Alexandria Harbour was full of them. 



Yellow-legged Hereing Gull {Larus cachinnans). 



A few to be seen off Cape Helles throughout the year ; many 

 at Imbros, where I saw a flock of fifty on a lagoon on July 10th ; 

 a few in Mudros Harbour, Lemnos, in January. 



Lesser Black-backed Gull {Larus f us cus) . 



Odd birds off Cape Helles, September 5th to 12th ; a few at 

 Lemnos in January. 



Levantine Shearwater {Puffinus yelkouanus). 



In flocks round Cape Helles— the first birds noticed on arrival 

 and always to be seen afterwards ; invariably in flocks, some- 

 times of a fair size. 



Mediterranean Shearwater {Puffinus kulili). 



One seen off Cape Helles between September 5th and 12th. 

 I saw it commonly in the Mediterranean. 



Eared or Black-necked Grebe {Podicipes nigricollis). 



Two in Mudros Harbour, Lemnos, on January 6th ; I saw 

 them well, and noticed the slightly upcurved bill.
