The wings of course. The wing bones the bird has start flapping when the bird accelerates, and usually in the air the bird keeps its wings straight so it may glide swiftly with the wind.
Also it has a developed streamlined body that helps it to avoid air resistance and sail through easily.

∙ 10y agoBirds are equipped with nine respiratory air sacs to supplement their smaller lungs. Birds have a higher metabolic rate, so they need higher amounts of oxygen. The air sacs enable birds to ventilate their lungs by allowing a unidirectional flow of air through the lungs. Put simply, this means that air moving through the bird's lungs has a higher oxygen content, to deliver more oxygen directly to the blood. This then helps to sustain the bird's higher metabolic rate.

What adaptations allow birds to get enough oxygen for flight?
1.For birds to be able to take flight or fly high enough and still obtain enough oxygen, the birds have air sacs. 2.(Air sacs are membranaceous receptacles which communicate with the cavities of the respiratory organs passages, and can through be filled with air.) I really hoped this helped, now remember the answer to the question is number 1. The definition of air sacs is number 2.
What does a bird's lung look like?
Birds have very different lungs than mammals because birds don't have a diaphragm. Air is pulled in by expansion of the rib cage and is drawn first into the lung, which instead of being arranged in blind-ended sacs (alveoli) are arranged into tubes. A second draw pulls the air from the lungs and into air sacs throughout the body cavities where additional oxygen is pulled from the air. The air is then expelled from the air sacs through the pharynx back into the atmosphere.
