The Eyes Which Guide the Dive
Osprey have amazing vision. Researches have studied their vision when they fish. Osprey have been measured to be anywhere between 5-40 meters above the water before performing a spectacular dive on their pray below. In some parts of the world, Senegal for example, it’s been noted that Ospreys will circle 100-300 meters above the water. The difference? The type of fish they are hunting. Fast-moving surface fish require the Osprey to be closer to the water for a cleaner, more accurate strike. In Senegal where there are schools of sardines and flying fish, Ospreys can spot them from high above thanks to the reflecting scales.
![Did you know?
Puffins mate on the water. The process of finding a mate include bowing, a male courtship display of its plumage with its head low to the ground. Head flicking, generally by sea in a raft, another display to attract the female with their colorful bills. And if successful:
Copulation. At sea, rarely (and usually unsuccessful) on land; male Wing-Flutters, female swims low in water with neck retracted; if receptive, female holds head higher, with rear of body low; pair swim slowly around each other, may Bill together before male mounts for 5–6 s (flapping wings for balance); female keeps head high though body submerged.
