One of Packer’s more sensational experiments took aim at a longstanding mystery. A male lion is the only cat with a mane; some scientists believed its function was to protect an animal’s neck during fights. But because lions are the only social felines, Packer thought manes were more likely a message or a status symbol. He asked a Dutch toy company to craft four plush, life-size lions with light and dark manes of different lengths. He named them Lothario, Fabio, Romeo and Julio (as in Iglesias—this was the late 1990s). He attracted lions to the dolls using calls of scavenging hyenas. When they encountered the dummies, female lions almost invariably attempted to seduce the dark-maned ones, while males avoided them, preferring to attack the blonds, particularly those with shorter manes. (Stuffing still protrudes from the haunches of Fabio, a focal point of Lion House décor.)
Consulting their field data, Packer and his colleagues noticed that many males with short manes had suffered from injury or sickness. By contrast, dark-maned males tended to be older than the others, have higher testosterone levels, heal well after wounding and sire more surviving cubs—all of which made them more desirable mates and formidable foes. A mane, it seems, signals vital information about a male’s fighting ability and health to mates and rivals. Newspapers across the globe picked up the finding. “Manely, lady lions look for dark color,” one headline said. “Blonds have less fun in the lion world,” read another.
