swallows
Because of their wings and the wind speed outside.
Freon can stay in the air for several weeks to several months after a leak occurs, depending on factors such as temperature, humidity, and air circulation.
It depends on the bird or animal laid the eggs. Some may stay good for days, some may stay good for months and some may stay good for years.
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!
Birds are able to stay airborne while seemingly flying in place due to a phenomenon called "dynamic soaring." This involves the bird using the wind patterns and air currents to generate lift and maintain its position in the air without expending much energy. By skillfully maneuvering in these air currents, birds can effectively stay in one spot while in flight.
The albatross can fly for months on end because its wings lock into place and it flies using the air currents being reflected by the water. Usually albatrosses land only to breed.
Air+Lizard= Bird
If it's sealed well and most of the air removed from the package, it can last months.

The buoyant force of air would be greatest for a hot air balloon because it relies on the principle of buoyancy to stay aloft. The heated air inside the balloon is less dense than the surrounding air, creating a greater buoyant force to lift the balloon. A bird and an airplane rely on aerodynamic lift generated by their wings to stay airborne, rather than buoyancy.

The Sooty Terns. They can go 3-10 years without landing.I read it on some places and heard it even on a Discovery Show about the island s in the Pacific about. Sadly couldn't find a scientific or confirmed place about this.
