Study reveals tale of Peacock's fan
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.
Their results are reported in the Journal of Experimental Biology.
