Researchers investigated reasons why different species of birds begin to sing at different times of the morning. They captured and examined birds of 57 species at different sites around England. They reported that there is a strong relationship between the diameter of a bird's eye and the time it starts singing in the morning: birds with larger eyes tend to start singing earlier.This is an example of:__________.

Final answer:

The relationship between the diameter of a bird's eye and the time it starts singing in the morning is an example of ecological adaptation.

Step-by-step explanation:

The relationship between the diameter of a bird's eye and the time it starts singing in the morning is an example of ecological adaptation. It shows how certain traits, such as larger eyes, can be advantageous for survival and reproduction in a specific environment.

In this case, birds with larger eyes are able to gather more light and have better visibility, which allows them to start singing earlier in the morning. Early morning singing may provide these birds with a competitive advantage in terms of attracting mates and defending territory.

This study provides evidence of how natural selection can shape the behavior and characteristics of different species based on their ecological needs and the selective pressures they face.
