👉 Cicadas, also known as woodpeckers or warblers, are a type of bird that spends most of their time in trees. They build and feed on insects called "woody" seeds, which are often found in oak trees. Cicadas have a distinctive call that they make to attract mates and warn off potential predators. Their wings are covered with a soft, sticky substance called "hairy" that helps them glide through the air.
