Tern Hunting of Fish
Terns are a group of bird species that hunt fish close to the water surface.Fish have adaptations to avoid being eaten,including cryptic coloration (most fish are dark along the back,even if they are silvery on the sides),habitually swimming at depths below those at which they are in danger from above,and taking evasive action if they see a bird diving toward them.Terns have their own cryptic coloration,most having white or light grey underparts so that they are difficult to see from below the surface,and they dive vertically toward the fish at the highest possible speeds.
