Many of
us feel a buzz when approached by a charming and attractive stranger,
but not in such a literal sense. When a peacock rattles his opulent train
feathers at a female of the species, it makes a sound at a specific frequency –
causing the crest on her head to vibrate energetically.
Peafowl (Pavo cristatus) are famous
for the spectacular train of feathers worn by males. The feathers are brightly
coloured and have iridescent “eyespots”. Males display them to attract females.
