Explanation

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the number of cones and rods in the eyes of night birds. We need to fill in the blank with the correct comparison between cones and rods.

2. **Identifying Rods and Cones**: In the context of vision, rods and cones are two types of photoreceptor cells found in the retina of the eye. Rods are responsible for vision in low light conditions (night vision), while cones are responsible for color vision and function well in bright light.
