Different Beaks, Different Foods
For some birds like hermit hummingbirds, the difference between sexes starts with the beak. Females hermit hummingbirds typically have curved bills while males wield straighter ones. Because the two sexes are better at drinking nectar from flowers that match their respective beak shape, males and females of the same species don’t compete with each other for food resources. Adaptations like these can provide benefits for the whole species.
