Predator vs. Prey: Green Heron vs. Bluegill

The struggle to survive isn't always a fair fight. Here's what separates nature's winners from its losers.

Stretchy Neck

More than half a green heron’s length comes from its oversized neck. In a flash, a heron can outstretch its neck to grab or stab a fish using its spear-like beak.

Sleek Blue Streak

A bluegill’s skinny body is built to slice swiftly through water and weave around vegetation.

Green herons use bait — such as insects, feathers, or twigs — to lure jittery fish into striking range.

Super Sight

A bluegill can see objects smaller than dust specks from 17 inches away. Spotting something as large as a heron isn’t a problem.

Swim Goggles

Herons have a transparent third eyelid, called a nictitating membrane, that protects their eyes underwater. Grasshopper Bluegill

And the winner is...

This one’s a tossup. Green herons only catch about half the fish they go after. But if the bluegill takes the bait, it’s likely to become sushi.
