As so often happens when attempting to manipulate waterfowl habitat, 

 especially in the Southeast, all igatorweed control provided mixed 

 blessings. Valuable waterfowl food plants, such as Cyperus spp. and 

 annual spikerush, increased temporarily. It appeared, however, that 

 over a period of several years the benefits of all igatorweed control 

 to waterfowl were outweighed by increased abundance of maidencane. (G.S.)

The food contents of 326 gizzards from 15 species of waterfowl 

 collected on Currituck Sound between 1947 and 1952 were analyzed in 

 detail by the aggregate percentage method. The collection period was 

 a time of generally low and fluctuating waterfowl populations on the 

 Sound. Percent frequency and percent volume results are presented 

 for 122 diving ducks (six species), 75 ruddy ducks, 97 dabbling ducks 

 (six species), 17 Canada geese, and 15 coots, both in groups and by 

 species. Plant foods composed 97 percent of the total. 



Potamogeton , Ruppia , and Najas were the overwhelmingly important 

 foods for all groups, totaling about 80 percent by volume for the 

 entire sample (72 percent identified and probably most of the 11 percent 

 unidentified vegetative material). Nevertheless, the 7 commonest 

 species--canvasback, redhead, ruddy duck, American widgeon, black duck, 

 pintail, and green-winged teal--each showed distinctive individual 

 differences in types and percentages of foods taken. Vallisneria , 

 now present in the Sound in good supply, did not appear in any of the 

 gizzards examined and \/ery possibly was relatively rare or spotty in 

 the Sound during the 1947-1952 period. (A. A.)
