Still Waters Posted July 25, 2013 #1 Share Posted July 25, 2013 Scientists in the US have used eye-tracking cameras to work out exactly what peahens find alluring in a peacock's tail fan. The male birds grow their trains of iridescent feathers during the mating, or lekking, season, fanning them out and rattling them to attract a mate. This team of biologists fitted peahens with eye-trackers to find out what they looked at during this display. http://www.bbc.co.uk...onment-23423074 Link to comment Share on other sites More sharing options...
