Why leks?
Jack Bradbury says that for groups that use lekking for reproductive means do this because
no other method is as good. It sometimes happen because females will often travel many miles to feed, so if the men are crafty and wait in the trees where she'll get her food, they stand to get a better chance of mating. On the other hand, so males will group in areas where there is absolutely no gain for the females, the females then have to actively search for a mate.
3 theories have been proposed as to why lekking occurs:
1. Female hotspots – males gather where females tend to travel
2. Male hotshots – ugly males that are less likely to get a mate on their own hang around good looking males in the chance of getting noticed.
3. Female preference – the males cluster because the ladies like to be able to have a bigger choice of who they want to mate with.
These 3 theories are all seen in practice in the real world, it all depends on how the population has evolved to which theory fits best.
