Paul commented "I have a rooster that gives an alarm call when anything larger
than a
Willie Wagtail flies past."
Researchers at Macquarie University in Sydney are looking at social
interactions of birds (particularly the humble chook). They have
determined that roosters that give alarm calls unnecessarily are trying to
improve their social status. However, hens soon recognise that these
individuals are all talk and soon learn to discount these false alarms.
Any gains that the rooster had made are soon lost.
