While in South America, you come across what you think are two groups of birds in the same location. They are nearly identical aside from their color. After years of observation, you conclude that the birds eat similar diets and share similar behaviors but do not reproduce with each other. These groups of birds appear to be an example of:

A. two different species on the basis of reproductive behavior
B. two different species because they live in different area:s
C. a single biological species

A. two different species on the basis of reproductive behavior

Explanation:

According to the biological species concept, organisms that mate with each order and successfully produce viable and fertile offspring are said to be of the same species. The biological species concept is based on the reproductive behavior of organisms.

Therefore, going by the information given in the question above, we can say that the two group of birds, that share the same location and are similar in appearance, share the same  behavior and diets, but do not reproduce with each other, are an example of two groups of different species on the basis of reproductive behavior.
