Draft 2 Week 10

Birds are monogamous so to choose a mate must be done carefully. Males and females have their own strategies to attract the mate. Males mostly have physical characteristics that are used for displays. In the red-winged blackbird, males will have a bright red color on the wing. However this is not the part that attract females. The color red is correlated with the food the male eats so if the male has a brighter feather, it means he has more territories. The more territory and resources the male has, the more female will be attracted. It is found that males will fight over territories to display how good quality they have.
