Cf. Crested Argus.<\/em><\/strong>\u00a0 The two arguses overlap in Malaysia\u2019s Taman Negara National Park and could be mistaken for one another if not seen well\u2014especially the females, which are similar in overall size, shape, and color.<\/p>

Males of the two species share approximately the same size and shape, although Crested\u2019s tail is longer and broader and its wing-feathers are less elongated than Great\u2019s.\u00a0 In overall coloration, Crested appears paler, grayer, and more noticeably spotted, while Great appears darker, browner, and more uniform.\u00a0 Their heads are more obviously different, as Crested\u2019s is feathered and has a broad, blackish mask framed by a white eyebrow and throat, whereas Great\u2019s is mostly bare and blue.<\/p>

Females are less conspicuously different.\u00a0 Both are warm-brown overall, with rusty tones on the neck and breast.\u00a0 However, the female Crested has widely spaced rows of dark-bordered white spots on its wings and tail, whereas female Great appears more uniform on the wings and tail.\u00a0 The heads of the females differ in the same way as the males\u2019 heads except that in both species that female\u2019s head coloration is less distinct than the male\u2019s.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
