- Birds evolved from reptiles and Archaeopteryx possessed both reptilian and avian features. Key avian traits include feathers, hollow lightweight bones, beaks, endothermy, and amniotic eggs. - Birds have highly specialized organ systems for flight including strong heart and respiratory systems. Their feathers provide insulation and flight abilities. - There are many orders of birds with varied traits like waterfowl that are aquatic, owls with keen vision and hearing, and songbirds that communicate through song.

Birds have several key features that help them survive and thrive. They have wings that allow most birds to fly, lightweight hollow bones, and claws and feet adapted for their environments and diets. Birds also have beaks suited to their food sources - some have crushing beaks, others curved or probing beaks. Their bodies are streamlined for flight and many have specialized leg and foot structures for swimming, wading, or perching.
