Green Heron

The Green Heron

Scientific name: Butorides virescens

Did You Know?
The green heron is one of the few birds that uses tools. That’s right. When fishing, the green heron sometimes uses bait and lures including insects, feathers and twigs to help nab its meal. This industrious bird drops the bait or lure into the water. If something nibbles at the bait, the green heron quickly extends its neck and uses its long pointy beak to spear its catch.

Is the green heron really green?
Well…its legs are yellowish-orange – and so are its eyes. Its neck and chest are a rusty red. But the green heron does have a green back, a strip of green feathers on its head and a green hue to its wings. Young herons have a white and brown striped neck and chest area. Their backs are brown with white and beige spots.

Would you believe?
Green herons use a couple of fairly common tactics to scare off would be predators. They have the ability to freeze and hold until the predator passes; they can also fly away quickly, squawking loudly. But their most unique defence is their excrement! That’s right. These birds aim their poop at potential predators – and with great accuracy. They often hit predators where it counts – in the eyes! The predator is, in effect, temporarily “blinded” and the green heron gets away!
