Hundreds of types of birds—of all different colors, shapes, and sizes—call West Virginia and Ohio home. But even among countless kinds of birds, they all share some traits. Flying is the primary source of motion for most types. Birds have feathers, which facilitate flight and provide camouflage and insulation. Birds also have beaks, and they lack teeth. A bird’s skeleton is strong but very lightweight, as their bones are hollow to help with flight. Many types of birds are migratory, which means they will travel to different areas during different seasons of the year. These migrations are typically initiated by changing weather conditions and the length of daylight. They lay hard-shelled eggs from which their babies will hatch. This necessitates nest-building, and most birds will build their nests from sticks, brush, and scraps in sheltered places — including in and around buildings, porches, and garages — to avoid predators. Birds eat many different things, including plants, fruits, nectar, and even carrion and small animals.
