Wildlife & Animals on Instagram: "Flying fox bats are the largest bats in the world, known for their fox-like faces and impressive wingspans. Instead of using echolocation like many smaller bats, they rely on their keen eyesight and sense of smell to navigate. When they gather in large colonies, they often make loud, repetitive barking sounds to communicate, defend their space, or alert others. These “barks” can echo through the trees, making their roosts surprisingly noisy. Video credit goes to
