EYES FOR HUNTING

Black-crowned Night-Heron

Reddish Egret

Excellent sight and eye placement are vital for these birds to find food. Eye placement on the sides of the head allows for better peripheral vision but makes for poor binocular sight. However, with eyes slightly forward on the head, the vision from each eye overlaps, providing decent sight in front and fairly good depth perception. Thus, the birds can capture tiny fish or pick up corn kernels or other morsels directly ahead of the bill.
