Night birds like owl have large number of rod and only a few cones. As on the other hand day light birds like kite, eagle etc have more cones and rods.
No, night birds have less cones than rods because cones sense bright light but these birds need rods to sense dim light in the night.
No it have the cones or rod cells as we have but its size is two times bigger than us, that's why owls can see clearly in dark but not in light.
No, those are mostly the functions of the rod cells. Cones are more for vision during the day, when you can see colours :)
The retina has two kinds of light sensitive cells, called photoreceptors, the rod and the cone cells. Rod cells are sensitive to absolute light levels (not color vision) while cone cells are used for color vision.
The cells responsible for the color vision in mammals are called as cones. I have been remembering the same by color vision by cones. That C and C. The brightness is perceived by rod cells. This is how you dispel the confusion. There are cones and rods to perceive the vision.
rods or rod cells
Rods, which perceive black and white and gray, and cones, which perceive color.

The eye .In there eye there is rod cells and cone cells. Rod cells detect color and Cone cells detect black and white. The cone cells let you see in the dark.
cones for color,rod are for black and white

There are two types of photoreceptors in the retina, cone cells and rod cells. There are 92 million rod cells in a retina. Rod cells function in less intense light and are important for peripheral vision and night vision.
The main difference between rod cells and cone cells is that the rod cell is responsible for detecting the dim lights only with black and white, and the cone cell is responsible for detecting the bright lights with colors. Also in retina, there are more rod cells than the cone cells. thirdly, defect in rods causes night blindness and defect in cones causes color blindness.

rod cells are to intensity of light as con cells are to colour.
Very light sensitiveHave more pigment than cones, so can detect lesslightSlow response to light

rods or rod cells
cone cells help you see colors while rod cells helps you see in dim light
