Detailed Solution

The birds that are active during the day have more cones than rods, and birds active during the night have fewer cones than rods in their eyes.
The day birds have more cones and fewer rods. This is because the cones are sensitive to bright light and can sense colours. Night birds can see clearly at night but not during the day. This is because their eyes have a large cornea and pupil, allowing more light to pass through. Night birds have fewer cones than rods in their eyes because cones are sensitive to bright light, and rods are sensitive to dim light. This is why night birds can see in the night, as they have more rods than cones.
