Male bee hummingbirds evolved to be much smaller than females, possibly because their diminutive size allows them to make faster and more elaborate courtship flights
at the University of California, Riverside, investigated evolutionary explanations.
The findings suggest discerning females may be driving the evolution of males’ flight athletics, and their diminutive size along with it. If females are preferentially choosing tiny aerial aces, it’s not yet clear what parts of the displays are most important to them. “We really don’t know if females are watching the males for how quickly they fly or if they’re just paying attention to the speed of the wings,” says Wilcox.
