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.
What else can I help you with?
How many air sacs do birds have?
Birds typically have nine air sacs: two cervical air sacs, two anterior thoracic air sacs, two posterior thoracic air sacs, two abdominal air sacs, and one interclavicular air sac. These air sacs help birds efficiently exchange gases during respiration and aid in maintaining their lightweight body structure for flight.
How do the air sacs in birds make them lighter?
I believe that air sacs on a bird are like floaties on a human. {If I am wrong please correct me.}
Are air sacs organs?
Yes they are and they are found in the lungs of birds.
What are birds lungs called?

What animal has four or five air sacs attached to each lung?

What is the purpose of air sacs in birds?
The purpose of the air sacs in a bird is to help digest food into the gizzard, and to help it breathe, and stay in the air longer and more smoothly. Hope this helps!
What is the function of a birds air sacs?
Can obtain more oxygen from each breath of air
How does a bird breath?
Birds breathe with lungs, in and out through beak and nostrils - pretty much like we do. Some have a sort of secondary system as well, with air sacs and even their hollow bones playing a role - but most it with lungs.
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.
Breathing mechanism in birds?
Inhaled air passes through the primary bronchus, and most enters the posterior air sacs as well as the lungs. During this passage, air that was in the posterior air sacs moves through the lungs air capillaries so that exchange takes place. During exhalation, the air in the posterior air sacs passes through the lung en route to the external environment. Again exchange goes on during exhalation.
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.
What characteristics is unique to birds?
Presence of five pairs of air sacs , syrinx , feathers and feathered wings , bill or beak are unique characters of birds .
