There is considerable variation in the crown of the males; in some 
it is solid black, while in others it is thinly barred with white. Inas- 
much as these bars are not terminal on the feathers, it is obviously 
not a matter of abrasion when they are absent. Zimmer (Amer. 
Mus. Nov., No. 584, 1932, p. 2) concluded from his study of this 
variation that “males just reaching maturity are more extensively 
white than old birds; at least, the lightest examples at hand from any 
locality usually show some traces of juvenal plumage not yet lost 
in molt...”
