Answer 1

$\Large{\underline{\underline{\bf{Answer:-}}}}$❐

In diurnal birds, 80% of the receptors may be cones (90% in some swifts) whereas nocturnal owls have almost all rods. As with other vertebrates except placental mammals, some of the cones may be double cones. These can amount to 50% of all cones in some species.
