Hollow bones improve the survival of birds primarily because they help them obtain more oxygen. The lightweight structure of hollow bones allows birds to be more efficient flyers, which enhances their ability to escape predators and travel long distances in search of food and nesting sites. Additionally, birds have a unique respiratory system that utilizes air sacs, making it easier for them to meet their high oxygen demands during flight.
