Foods of northern pintails, American wigeon and long billed dowitchers were determined by collecting birds from May to August, in 1985-1986 at Selawik National Wildlife Refuge in northwest Alaska. The proportion of invertebrates in the diets of prelaying (n=5), laying (n=11) and post laying (n=16) adult female pintails was not different (range of 27%-33% aggregate percent, dry weight, p>0.05).
