"Bent, U. S. Nat. Mus. Bull. 162, 1932, 87, states that in this "plumage the sexes 

 are much alike, except that in the young male the crissum, lower belly, and flanks are 

 black, and the center of the breast is suffused with brown, whereas in the young 

 female these parts are white; these characters are conspicuous in flight. . . ." The 

 material studied in the present connection does not bear this out ; I cannot help but 

 conclude that Bent was misled by birds in an advanced stage of the postjuvenal molt. 

 The true juvenal plumage is worn for a short time only before feathers of the first 

 winter (adult) plumage begin to appear, first on the breast, then on the abdomen.
