Concerning the annual appearance in autumn and winter 

 of ducks and geese in the Zeeland waters, the late Mr. T. 

 M. Pike, who has been shooting with the puntgun during 

 more than twenty years on our coast, has given me inte- 

 resting notes. He wrote to me: »The wigeon *) is the most 

 numerous here ; it arrives in small numbers in September, 

 becomes more numerous in October and November. Probably 

 a good number pass through further south, but here retain 

 some 4 or 5 thousand right through the winter. Next 

 comes Anas bosc/ias, not so numerous as penelope, but still 

 to be reckoned by thousands, they become scarcer as the 

 winter draws in, mostly 1 believe, owing to the decoy here 

 at Vrouwepolder, which is the best in Holland and catches 

 chiefly duck 2 ) and teal 3 ), not many wigeon. Teal are numerous 

 in October and November and then disappear, being got 

 by the decoy and some going on south. Pintails 4 ) remain 

 in small number throughout winter, but are most numerous 

 on migration in autumn and again in spring. Shovelers 5 ) are 

 here in some numbers from October to March. I once 

 killed a garganey G ). The gadwall : ) does not occur here, but is 

 found on the East Schelde on the Roggenplaat and is 

 caught in some numbers in the Schouwen decoys. It is 

 more a pond bird, that is does not come to the tide, unless 



1) Mareca penelope. 2) Anas boscfias. 3) Net Hon crecca. 



4) Dafila acuta. 5) Spatula clypeata. 6) Qucrquedula querquedula. 



7) Chaulelasmus strepera.
