province Zeeland, by Mr. A. Man in ’t Veld.

Reporter Mr. A. L. H. H. Waterbeek. 
Ring 371, marked 28 July 1911, shot in the second 
half of September 1911 at Duivendyke on Schouwen, prov.

between Bergues and Dunkerque, Northern France. Reporter

Ring 386, marked 28 July 1911, shot in the second 
half of September 1911 at Duivendyke on Schouwen, prov. 
Zeeland. Reporter Mr. F. van der Bout. 
Ring 387, marked 28 July 1911, caught 23 October 1911 
in a duck-decoy at Willemsdorp, prov. Zuid-Holland. Re- 
porter Mr. C. J. Schram. 
Ring 418, marked 13 August 1911, shot 4 September 
1911 in the polder Oud Noord-Beveland, prov. Zeeland. 
Reporter Mr. C. van Oeveren. 
Moreover in September and October some mallards have 
been caught and released in the same duck- decoy at Ellemeet 
on Schouwen, where they were marked in July and August. 
These records prove that a good deal of the ducks of a 
decoy remains on the decoy or in its neighbourhood; a 
single specimen seems to migrate early in the autumn, as is 
proved by the bird shot 9 October 1911 in Northern France. 
Larus argentatus, marked at Callantsoog, prov. Noord- 
Holland by Dr. J. J. Blanksma.
