Why birds of a feather lek together
Date:2/29/2012

ow males in each lek get all the girls. So why do other yellow males help? The new study finds that the yellow males within leks are more closely related than males between leks. This suggests the possibility that even less successful relatives may profit from lekking with their Don Juan-like cousins.

"We think that these yellow males that help out their relatives are benefiting by passing on their family genes indirectly," says Uy. "It's a bit controversial, but it adds evidence of what is called kin selectionselection driven by kinshippushing some of the dynamics of lekking, as well affecting the interactions between two species when they re-establish contact."
