Potoos are some of the most appealing birds in the world. They belong to the nocturnal bird family. You might think that’s an exaggeration, but it’s true. At first look, they may sound scary, but when they tend to rest where they habitually sit, and they will usually never go too far from their stump. Potoos can be white, gray, brown, beige, burgundy or mottled with a mixture of colors that blend in perfectly with tree bark. When they stopped by a tree to rest, they are not moving so they look like a branch of the tree. During the day, the common potoo’s eyes are yellow, but at night, they turn orange. Half of their eyes were closed, but they could still detect the other’s presence. Their small beaks are essential for their survival. And it is one of the creatures found in the Amazon rainforest.
