The eyes have it

“Everyone’s sort of the same height when your looking form a bird’s eyes…”

Marcus Dunstan

Vision is the most important sense for birds. They have been referred to as two eyes with wings, having the greatest visual acuity of any vertebrate species. Birds have a unique pectum oculi structure which allows variation in lens shape, to a degree unknown in mammals. Birds of prey have an increased density of retinal receptors to give acuity, which combines with forward eye placement to give excellent binocular, distance vision. Nocturnal species have a high number of retinal rod receptors to function well in low light. Seabirds have a distinctive red or yellow oil in their eyes to improve vision in hazy conditions. Bird photographers aim to focus on the eyes to give their subjects greater impact and maximum character. #aimfortheeyes #letsmakelemonade
