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.
