The First Ever Chimp Fashion Trend: Sticking Blades of Grass In the Ear

A group of chimps at the Chimfunshi Wildlife Orphanage Trust sanctuary in Zambia have a new fashion statement: sticking a blade of grass in one ear.

Chimps are highly intelligent and are known to use grass to fish for termites, but after extensive study, scientists have concluded that there is no discernible purpose for what they’re calling the “grass-in-ear behavior”.

It all started back in 2010 when an older female named Julie started sporting a long blade of grass from her ear. Julie was a sort of role model for the other 11 chimps in her group, and they paid close attention to her strange new behavior.

After repeatedly observing the behavior for a while, other chimps in the group began to join. Although Julie has since passed away, seven of the 11 chimps from her group still sport blades of grass from their ears today.

Edward van Leeuwen is a primate expert at the Max Planck Institute in the Netherlands who led a study to examine the odd behavior. Him and his colleagues spent a year observing four groups of chimps at the Chimfunshi orphanage.

Despite the fact that all four groups lived in the same grassy environment, only Julie’s group exhibited the “grass-in-ear behavior”. After extensive observation, van Leeuwen concluded that there were no genetic or ecological purposes for the behavior- it had simply become part of the group’s culture.

“The chimps would pick a piece of grass, sometimes fiddle around with it as to make the piece more to their liking, and not until then try and stick it in their ear with one hand… Most of the time, the chimps let the grass hanging out of their ear during subsequent behavior like grooming and playing, sometimes for quite prolonged times. As you can imagine, this looks pretty funny,”

says van Leeuwen. He also pointed out that the behavior isn’t much different then the fads that emerge amongst humans, comparing it to, “wearing earrings or certain kinds of hats.”
