black ; and the longest innermost secondaries are black with a broad white 

 shaft-line. Bill black; legs and feet light brown; irides yellow. The 

 female differs from the male in having a much smaller crest, which is 

 almost uniform brown ; the head, neck, and upper breast are greyish brown; 

 the underparts are similar in colour to those of the male, but the flanks 

 are not vermiculated. The upper parts below the neck closely resemble 

 those of the male, but are somewhat browner. Young in first plumage 

 closely resemble females, but are much browner. Males of the year are 

 intermediate between adult males and adult females. Young in down 

 are brown above, with tufts of white on the wings and on the sides of 

 the rump, and the underparts are nearly white.
