From big think – devious roosters:
Manipulation is a vicious yet not uncommon human trait. Our ability to alter our surroundings in order to take advantage of a situation was recently on display in The Wolf of Wall Street, when Jordan Belfort flips worthless penny stocks and builds an illegal career from the deal. Of course, this is but one example of something occurring around the planet daily: the reorganizing of facts to gain ground over another. Human beings are not the only animal skilled at this. Take the chicken. When spotting an aerial predator such as a hawk, a rooster will sometimes send out a danger call, putting himself in harm’s way. It was assumed that he was doing that to protect the female chickens and his offspring, drawing attention away from them in what appeared to be a chivalrous display of bravery. Well, not quite. A research team at Macquarie University rigged the chickens with special microphones, dubbed Chicken Big Brother 2.0, to watch their barnyard habits. Turns out the male will call out more often when safely protected underneath a bush while another male was exposed. This competitive advantage put his companion in danger, leaving more resources (and ladies) for him.
