Correct Response: C. A monogamous mating relationship in birds is when a male and female bird form a pair bond for one or more nesting seasons and work together to raise their young. One situation in which this relationship is advantageous is when the young require constant feeding. Male and female sexual dimorphism (A) is when certain traits, such as coloration, are inherited in a male- or female specific pattern within a species. Cryptic coloration (B) helps an organism blend in with its environment and is an advantage for hiding from predators. An example of seasonal migration (D) is birds following a seasonal pattern in moving from one region to another in order to obtain necessary resources, such as food or nesting locations. None of these characteristics are specifically tied to monogamous mating relationships in birds.
