DescriptionPavo cristatus Linne.jpg | Pavo cristatus Peafowl are most notable for the male's extravagant display feathers which, despite actually growing from their back, are known as a 'tail' or train. This train is in reality not the tail but the enormously elongated upper tail coverts. The tail itself is brown and short as in the peahen. The colours result from the micro-structure of the feathers and the resulting optical phenomena. The ornate train is believed to be the result of female sexual selection as males raised the feathers into a fan and quiver it as part of courtship display. Many studies have suggested that the quality of train is a honest signal of the condition of males and that peahens select males on the basis of their plumage. More recent studies however, suggest that other cues may be involved in mate selection by peahens. |

JPEG file comment | Indian Peafowl (Pavo cristatus): Peafowl are most notable for the male's extravagant display feathers which, despite actually growing from their back, are known as a 'tail' or train. This train is in reality not the tail but the enormously elongated upper tail coverts. The tail itself is brown and short as in the peahen. The colours result from the micro-structure of the feathers and the resulting optical phenomena. The ornate train is believed to be the result of female sexual selection as males raised the feathers into a fan and quiver it as part of courtship display. Many studies have suggested that the quality of train is a honest signal of the condition of males and that peahens select males on the basis of their plumage. More recent studies however, suggest that other cues may be involved in mate selection by peahens. |
